Diaphragms for Parker Vacumtaics

Latex diaphragms with the red pellet installed. For use in Parker Vacumatic fountain pens. Available in 3 sizes: Debutant, Standard and Oversize.
***Note: All 51 vacs use the Debutant (DEB)  size.

Remember to cut total length of Vac diaphragms down to 1 1/16" before installing, or they won't work too well.

We also sell talc to aid in diaphragm installation.  Our D15 Pellet Pusher helps push the diaphragm's ball into the pellet retainer.  The balls that come inside all of our Pentooling's diaphragms are available for sale, too. 

Additional sizing notes from Dale: A debutant diaphragm is the most commonly used. All plastic filling units as well as all 51s use a deb diaphragm. A standard (sometimes called medium) diaphragm goes in Maxima pens. Only oversize Vacs with a Lockdown unit uses an Oversize diaphragm.
