Description

The BECA 150 - 152 - 154 profiles are single acting composite rod seals composed of a filled PTFE friction ring and pre-tightened rubber O'Ring. They can be assembled in grooves according to standard ISO 7425/2. Option of connecting the seal to a back-up ring.

Advantages

Optimal sealing in static and dynamic applications
Low friction coefficient; no stick-slip effect
Excellent abrasion and extrusion resistance
Wide temperature range and excellent chemical resistance, depending on the material selected for the O'Ring
