AirJoe Tuning piston seal short stroke

AirJoe tuning piston seal 26 mm short stroke

Self-lubricating piston seal in a tall design for Weihrauch HW77/97, ​​made of a high-quality elastomer with solid lubricant . Thanks to the 10 mm raised design with a concave top, no additional adapter is required to shorten the piston stroke in your HW77/97. The short stroke results in a shorter shot development time and thus increases precision. It also increases hold sensitivity .

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

The piston seal is specifically designed for the HW77/97 and 85/95/98 models. The stroke of the HW50/57/99 is too short for short stroke.

The shortened stroke can affect the performance of your bouncer. We recommend using our Teflon Jonas washers for fine-tuning.
