AirJoe Tuning piston seal short stroke

AirJoe tuning piston seal 26 mm short stroke

Self-lubricating piston seal in high design for Weihrauch HW77/97

Thanks to the 10 mm higher design, no additional adapter is required to shorten the piston stroke in your HW77/97. Short stroke leads to a shorter shot development time and thus increases precision. In addition, the hold sensitivity is increased, popular with HFT shooters.
Concave shaped top made of a high quality elastomer with solid lubricant.

Thanks to the flexible sealing lip, the seal adapts precisely to the inner wall of the system, a clear advantage over rigid seals. The piston sits perfectly centrally thanks to the guide ring. The seal is slightly harder than the injection-molded original from Weihrauch.

The piston seal is designed for the models HW77 and 97

The shortened stroke can change the performance of your bouncer. We recommend using our Teflon Jonas discs for fine tuning.
