Sheaffer PFM Front Seal

Moulded from durable silicone rubber this item is accurately dimensioned from the original Sheaffer PFM specification, this seal replicates the action found in the original new pen

Do not confuse this seal with alternatives which resemble tap washers. I make these for owners who respect the original design of their pens

Please see the cross section view which clearly demonstrates the thinner angled inner section which allows a slight movement during use whilst retaining a good seal

The colour is black (shown in blue for clarity only)
