Replacement 25mm OD Piston Seal / Washer for Weihrauch made Air Rifles. If your Piston seal is split or worn, then the compression chamber will lose pressure past the piston, lowering the power and accuracy of the Rifle. It is recommended to change the Piston Seal / Washer either when reduced power is noticed, or if the spring is replaced.

Parachute style seal that tapers the full thickness of the seal, Molydenium grease can be used, but PTFE is recommended to reduce Dieseling and prolong the life of the seal.
