To help with the refitting of the vacumatic sac (also called a vacumatic diaphragm) into the unit use the PELLET PUSHER
to ensure a secure fit. When fitting the vacumatic sac into the vacumatic unit FRENCH CHALK
is used. When fitting the unit back into the barrel SILICON GREASE
can be used to ensure a smooth and snag free fitting.
Available in 3 sizes.
Small. Fits the Deb and Sub Deb. Vacumatic Fountain Pens.
Medium. Fits the Standard and Major Vacumatic Fountain Pens.
Large. Fits the Oversize and maxima Vacumatic Fountain Pens.
IMPORTANT. The new diaphragm should be cut to a maximum length of 30mm to ensure it does not foul the breather tube when the plunger is depressed.
