BECA 150

BECA 150 - 152 - 154

Description

The BECA 150 profile is a single acting composite rod seal composed of a filled PTFE friction ring and a pre-tightened rubber O'Ring. It follows the rod diameters, in line with the standards MIL-G-5514F and AS4716.

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
