Pen Sacs & Restoration Supplies
Replacement sacs (bladders) for restoring vintage fountain pens. Our latex rubber sacs are made using the same latex formula and on the same equipment used by the White Rubber Company, which supplied most of the major pen manufacturers with sacs from 1919 to 1985.
Vacumatic Diaphragms Replacements for the Parker Vacumatic filling systems. Use the Deb size for the Lockdown Slender, “51s”, all Speedline & plastic plunger models except Maxima & Senior Maxima. Each diaphragm does include a pellet that secures the diaphragm into the cup of the filler unit.
For information on sac sizes and what pens they fit, please refer to our Sac Size Guide.
