We offer only a limited selection of parts. The main reason is simple: most vintage pen parts aren't interchangeable. They exhibit a maddening range of variations, and often as not even a correct original part must be hand-fitted. In most cases, it takes as much time to figure out what a do-it-yourself pen repairer actually needs as it would take to do the job ourselves, so please don't take it amiss when we ask you not to inquire about pen parts other than those listed.
Please make certain that the part you are ordering is the one you need -- returns of parts will not be accepted unless defective or not as described. This also applies to renewable components, such as sacs and seals, as well as pencil lead, erasers, and the like.
Unless otherwise noted, all parts are factory-made originals (this does not apply to sacs and seals, where factory originals would be age-hardened and unusable). If unused, they will be labelled "NOS" (new old stock); otherwise, condition will be used but sound. As noted above, some hand-fitting of parts may be required, and nibs (even new old stock) may need some tweaking in order to give the exact ink flow and "feel" on paper that you prefer. Prices listed below do NOT include shipping and insurance; if you wish to buy more than one of an item, quantities can be adjusted within the shopping cart before checkout.

These 5-inch nib smoothing disks aren't cheap, but they are the best! The industrial diamond coating resists being scraped off the extra-tough mylar backing -- one can even run the edges of these disks between a nib's tines to smooth the inside edges of the tipping material. Can be used wet or dry, will outlast other polishing media many times over -- one disk should easily be good for smoothing dozens of nibs.
Available with particle size of either 0.1 micron (ultrafine, for smoothest finish work; dark green) or 1.5 micron (very fine, offers faster deburring; light green). $12 per disk.
NOTE: These are much finer than mylar-backed abrasives sold for hobby use, while the grit size is far more closely controlled. This chart gives rough equivalencies between difference abrasives scales, listing abrasives of up to 0.5 micron as equivalent to 100,000 mesh (our finer grade is, of course, five times finer yet).
Cleanout bulbs are essential for pen restoration and maintenance: use them to flush out accumulated ink deposits and sediments from sections, feeds, and nibs, or to clean out dried ink from Parker 61 capillary reservoir units. Similar bulbs were furnished by Waterman for routine cleaning of their eyedropper-filling pens at the beginning of the 20th century. Cheaper, less risky, and often more effective than an ultrasonic cleaner! These sturdy, thick-walled rubber bulbs will last for years. The large bulbs will fit the section nipples of most pens, as well as Parker 51 and 61 nib openings. The small bulbs will fit slender pens and miniatures, such as Eversharp Bantams and Peter Pans. We also now have extra-large bulbs (not shown) with the same opening size as the large bulbs, but twice the capacity. $4 each.
Test tube brushes are another must-have. This set includes one large, one small: the first is a good general purpose brush for caps and most barrels; the second is ideal for the narrow barrels of eyedropper-fillers, and for cleaning out sections after feed removal. Two brushes, one price: $6
If you've worked on vintage piston-fillers, safeties, pump-fillers, or plunger-fillers, you know that replacement seals are almost never available ready-made -- you have to cut them yourself, using tools like these. This seal-cutting set consists of six punches that will cut disks in cork or rubber from about 4 to 9 mm in diameter. This nicely covers the range required for the great majority of fountain pens. Note that most experts cut their seals slightly oversize, bringing them down to final dimensions with sandpaper while spinning them in a drill or lathe. May require sharpening for best results -- just twist them against a whetstone or file. Six punch set, $20
Do you have an eyedropper-filling pen in the box, complete with eyedropper? Chances are, the eyedropper's bulb has long since hardened and shattered. These latex bulbs make accurate replacements, at only $0.60 each.
Thick 1.1 mm lead for older mechanical pencils (interchangeable with leads nominally designated as .046", 1.18 mm, and 1.2 mm), as well as .9 mm (.036") lead in various grades and colors. These are fresh production from Autopoint. Each tube contains 12 leads, each 1 3/8" long (3.5 cm). Black lead is $2 per tube; colored lead is $2.50.
M (1.05 mm) was one of the other lead sizes most commonly used in 19th-century mechanical pencils, and now virtually impossible to find. Our true 1.0 mm lead will fit M nozzles, albeit a bit loosely. A thin coat of shellac will bring the lead right up to 1.05 mm, or it can be rubbed with beeswax to hold it in place. Another approach is to give the nozzle tip a slight squeeze for a snug fit. Note that current-production pencil lead sold as 1.0mm is actually 0.9mm.
Five 6 cm pieces for $5
Esterbrook screw-in Renew-Point fountain pen nib units are listed here
Newly-manufactured precision stainless steel breather tubes for Aerometric 51. Our manufacture, made to original Parker dimensions. Replacements for the original sterling silver breather tubes, which are commonly found broken or badly corroded. Properly sized and located side vent hole is crucial for proper functioning. Available in both standard and Demi lengths -- please specify how many of each are required. If not specified, standard size tubes will be sent.
$10 each, 3 for $24, 10 for $65, 50 for $250.
(Parker 51 Aerometric repair notes here)
Our custom made all-metal adapters permit use of ballpoint refills taken from BIC stick pens in Parker fiber tip pens, including slender models such as the 35 and 45. Fiber tip refills were discontinued long ago, and these are the only adaptors currently on the market. Full instructions here. $30 each.
Hood for Vac-filling and standard Aerometric full-size 51, without recess for O-ring (will not fit late 61-style 51 Mark III pens with coarse threads): black, NOS, $20 each
Dark blue (not shown; for Vac-filling 51s, more greenish than the Aerometric blue), NOS, $30 each
Clips for late production 51 Aerometrics (38 mm long, 12 ribs; will fit earlier pens, but clip length may not exactly match the original) c. 1960, NOS, gold filled or chrome plated, $35 each.
Desk base holder fixture, black with gold plated trim, Parker "halo" imprint, holder with ball end to fit "Magnetix" magnetic bases, will accommodate a number of Parker desk pens of the 1950s-80s (21, 45, 51); NOS: $30 each
Desk base holder fixture, black with gold plated trim, Parker "halo" imprint, swivel holder, fits a number of Parker desk pens of the 1950s-80s (21, 45, 51); restore a desk set or make your own. NOS: $30 each
Replacement barrels for 1930s Pelikan 100 piston-fillers, newly-made in USA from transparent acrylic (NOT Pelikan production). Finish machined, can be polished internally and externally for additional transparency. Barrel sleeve (binde) fit is deliberately designed to be on the loose side, so as to minimize risk of splitting a vintage binde.
Barrels can be used with or without barrel sleeves, but note that there will be a slight step where the barrel abuts the filler unit if no sleeve is mounted. Make your own customized demonstrator!
$50 each. Colorless clear is only color available (green, blue, and red are now sold out).
Replacement flat coil springs for Sheaffer Snorkel pens. The originals are prone to rust, especially if there is any leakage into the barrel interior from a failed sac or point seal. Even if the rust is removed, there is almost always residual pitting, and a Snorkel mechanism will not retract and extend smoothly if the spring is at all rough. Not original Sheaffer production, but newly manufactured to original specifications, 3 for $18 or 100 for $300
Skyline pencil clip assembly, NOS, $10 each
6813: Waterman lever box assembly for later production 58: original new old stock, fits 22 mm long, 3.2 mm wide barrel slot, nickel plated.
9500: Waterman lever box assembly: original new old stock, 21 mm long, fits 16 mm long, 2.2 mm wide barrel slot, gold plated.
9501: Waterman lever box assembly: original new old stock, 23 mm long, fits 16 mm long, 3 mm wide barrel slot, gold plated.
These traditional latex rubber sacs are all fresh production from the Pen Sac Company (the inheritors of the old White Rubber Company's ink sac operation). A sac of size "n" will slide freely into a hole n/64ths of an inch in diameter. Unless otherwise noted, all sacs are straight (i.e., not necked or tapered). Sacs are sold by the bag, $12 for five sacs, or an assortment of twelve in the most useful sizes (our choice) for $24.
NOTE: While latex rubber sacs can last for years under normal conditions, the use of certain inks can lead to rapid failure. Read more about ink selection for vintage pens here, and about sac materials and installation here.
100% silicone sacs will outlast conventional latex sacs several times over, and are unaffected by the most reactive inks. As far as we know, these are the only genuine silicone sacs currently on the market (note the longitudinal seam lines: real silicone sacs have to be injection molded). Latex sacs can release sulfur compounds as they age, which discolor plastics such as celluloid. To preserve original color, 100% silicone sacs are the best choice. Other sacs advertised as "silicone" are actually PVC (vinyl) -- a material not compatible with celluloid: over time, PVC leaches a plasticizer which is known to attack celluloid). More on choosing sac materials and their various pros and cons here. These sacs are shorter than their latex equivalents (14 and 15 sacs are ~70 mm long; 17 sacs, ~85 mm; 18½ sacs, ~80 mm). Sacs are sold by the bag, $10 for a bag of five sacs, or $20 for a bag of twelve assorted (three of each size). Bags of 25 sacs are $40; bags of 100 sacs are $100. The bag of 100 assorted sacs includes 25 of each size for $120.
NOTE: Silicone is more permeable than latex, so greater attention to maintaining the nib elevated may be necessary when a silicone-sacked pen is not in use.
The PVC ("Pli-Glass") sacs that Parker used for their 51 Aerometrics are famously durable. Nonetheless, they do stain and darken, and eventually they will give out. We can now offer reproduction sacs made of the same material and as durable as the originals. Please note that these may stain when used with highly pigmented inks, and that they are not recommended for use in pens made of celluloid or cellulose acetate.
5 sacs for $10, 50 for $75, 100 for $100.

Certain pens require special ink sacs, which we offer at $8 for a bag of three. Vacumatic sacs (Parker originally called them "diaphragms") come in three sizes. Confusingly, most Vac-filling pens -- including most Parker Vacumatics, all Vac-filling Duofolds, and all Vac-filling 51s -- use "small" Vac sacs. Full-sized lockdown-filler Vacumatics use medium Vac sacs. Oversized Vacumatics (including some but not all Maximas) use large Vac sacs, which we will be selling soon.
Waterman Ink-Vue pens use another special sac. Standard and Deluxe Ink-Vue pens use standard-sized Ink-Vue sacs, while the little Lady Patricia Ink-Vue uses a smaller sac. Note that the late 5116 Ink-Vue with its one-piece barrel uses a completely different sac, that is not currently manufactured.
NOTE: To order 100 of items sold in bags of 20, set the quantity in the cart at 5, then click Recalculate.
O-ring seals for Parker 51 Aerometric pens with a recess in the hood (shell). Seals against the clutch ring -- do not install if there is no seal recess in the hood! Newly manufactured to original specifications.
$5 for 5 or $25 for 50
O-rings for Sheaffer pneumatic-fillers (these fit inside the end of the barrel, making an airtight seal with the plunger), newly manufactured to original specifications, now in long-lasting ethylene-propylene*: 20 for $10 or 100 for $25
NOTE: small rings fit Snorkels and most Touchdowns, including Imperials; large rings fit PFMs, 1949 Touchdowns (the fat first-year model), and Touchdown Tuckaways. (installation instructions here)
Point seals for Snorkel and PFM (these fit inside the nib/section assembly, sealing around the extending filler tube). Custom-made to our specifications in long-lasting ethylene-propylene*. These seals are of critical importance, for when old seals leak they may allow ink to be sucked into the pen's interior, causing the spring to rust and freeze up the mechanism: 20 for $16 or 100 for $50
* Ethylene-propylene seals should last at least twice as long as those made of ordinary rubber, which are vulnerable to oxidization, and especially the effects of ozone. Use only with pure silicone grease, keep away from petroleum-based lubricants.
Replacement ink sacs for Snorkel, Touchdown, and PFM repair are listed above. Correct sizes are as follows: #14, for Snorkels; #15, for slender Touchdowns, including Imperials; #17 or #17½, for Touchdown Tuckaways, PFMs, and fat-barreled first-year (1949) Touchdowns. Note that a half-size difference is only 1/128 inch (0.2 mm) -- not much more than the typical range of dimensional variation for dip-molded sacs.
(more on sac selection for pneumatic-fillers here)
Repair kits for Sheaffer pneumatic-fillers, $10 each. Snorkel and PFM kits each include three sacs, three point seals, and three barrel-plunger seals; Touchdown kit comprises a total of four sacs and four barrel-plunger seals, two each of each of the two sizes used. Sac lengths may differ from those shown in the illustrations above. Touchdown repair instructions may be found here; Snorkel and PFM instructions, here.
These kits are also available with silicone sacs at no additional cost (pros and cons of silicone sacs explained here).
General-purpose piston-filler seal replacement kit. Assortment includes 40 O-ring seals, 10 in each of four different graduated sizes. Easily installed replacements for traditional cork seals, use singly or in pairs, or in combination with greased felt washers. Will fit a wide variety of vintage European piston-fillers -- we have used these on pens by Aurora, Kaweco, Montblanc, Osmia, Pelikan, Soennecken, and others. $25/kit
(NOTE: This is the same assortment offered for Conklin Nozac repair below)
Piston seals for Pelikan 100 and 100N. Use in pairs as replacement for original cork seals -- will not fit pistons originally made to use synthetic seals.
Better sealing, more durable, lower friction than cork. Easy to install, use with silicone grease for smooth action. Shown above installed in one of our transparent acrylic replacement barrels (at left) and in an original celluloid barrel (at right).
Piston seals for Pelikan 100N, 400, 120, and 140 family pens. Secure snap-fit replacements for original synthetic seals, new manufacture, shown below mounted on Pelikan piston-filling mechanisms (not included). These seals are modeled on an original Pelikan piston seal design of the early 1950s. They come in two sizes: the clear and black seals are designed for precise sealing in barrels with a 9.0 mm inner diameter; the green seals are optimized for diameters of 9.1 to 9.2 mm.
In general, the larger green seals fit earlier production Pelikan 100N series pens with celluloid barrels, while the smaller clear and black seals fit late-production 100N pens with acrylic barrels as well as the 120/140/400 series pens. Unfortunately, there is much inconsistency in Pelikan barrel size, so we recommend that you order a mix of sizes -- let us know how much of each color to send.
Piston seals for Conklin Nozacs (use in pairs). Kit includes 40 O-ring seals, 10 in each of four different graduated sizes. Sizes A and B will fit most standard-sized (5000-word) Nozacs, use C or D for oversize pens (7000-word). O-rings stretch over the piston head, seal tighter with less friction than any other seals we've tried. No more time-consuming gluing together of split cork! May also be used for a wide range of other piston-fillers. $25/kit
(installation instructions here)
Packing seals for Waterman safety pens (use two or three to replace the original cork shaft seal). Will fit pens up to #5-size (Waterman 45). Newly-manufactured in fluorocarbon rubber** for maximum durability and chemical resistance.
20 for $15 (installation instructions here)
Packing gaskets for plunger-fillers (used to replace original innards of Sheaffer or Eversharp packing units). Newly-manufactured in fluorocarbon rubber** for maximum durability and chemical resistance.
20 for $12 or 100 for $25 (installation instructions here)
** Fluorocarbon seals are extremely durable, resisting wear & weathering far better than standard synthetic rubber seals (estimated lifespan in industrial settings is up to 20 years, versus 2 to 5 years for the standard synthetic rubber, butadiene).
Long-necked applicator, perfect for applying solvent cement in plunger-filler repair -- also a superior filler for eyedropper-filling pens (the long, thin tube reaches further into the barrel, filling it more neatly):
$0.50 each, ten for $2.50
Sheet stock for plunger-filler piston washer seals, top-grade synthetic rubber, correct stiffness and thickness for optimal filling and long service. This is not an off-the-shelf product: the nonstandard thickness is the same as that of original Sheaffer plunger-filler piston seals, works equally well for contemporary Eversharp and Conklin plunger-fillers.
$6 for a 3" x 3" sheet (7.5 x 7.5 cm), three sheets for $15.
High grade industrial felt, 1/16" (1.6 mm) thick; 95% wool, tough and dense, used in packing units and in some piston seals, layered with rubber washers, the felt serving to absorb and retain the silicone grease that seals and lubricates the seal assembly. Not to be confused with fabric and craft store felt, which is thin and flimsy and insufficiently absorbent.
$4 for a 4" x 6" (10 x 15 cm) sheet.
Special thin-wall Teflon™ tubing will not corrode, low-friction surfaces resist ink residue buildup. Approximately .074" OD, cut to length and taper end to make replacement breather tubes for Vac-filling Parker 51s and later 51s with plastic breather tubes, Parker Vacumatics, Eversharp Skylines, and many other pens.
5 feet for $5, or 50 feet for $30.
NOTE: for Parker 51 Aerometrics that use a long thin metal tube, replacements are listed here.
