Tuning piston seal HW30(S) self-lubricating

Self-lubricating piston seal, a further development of the world-leading green piston seal from V-Mach, proven thousands of times over. This seal is manufactured in an identical shape with a concave top surface from 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 significant advantage over rigid seals. The guide ring ensures the piston sits perfectly centered in the system. The seal is slightly harder than the injection-molded original from Weihrauch, while the sealing lip is slightly softer.
