Description

The BECA 535 profile is a double acting composite piston seal composed of a pre-tightened rubber square ring and a trapezoidal polyurethane or TPC (Hytrel) friction ring, depending on the type of application.

Advantages

Optimal sealing in static and dynamic applications
Excellent abrasion and wear resistance
The square ring does not twist under pressure
