Tuning piston seal green HW50

The 1000-times proven and world-leading V-Mach piston seal has been reissued in close cooperation with the English tuner Lyndon Lewington from ARC Tuning.

Thanks to its flexible sealing lip, the seal adapts precisely to the inner wall of the system, a clear advantage over rigid seals. The piston sits perfectly centered in the system by means of the guide ring. The seal is slightly harder than the molded original from Weihrauch, the sealing lip is slightly softer.

• replaces the Weihrauch seal
