Description

The BECA 170 profile is a double acting composite rod seal composed of a filled PTFE friction ring and a pre-tightened rubber O'Ring. It meets the standards MIL-G-5514F and AS4716.

Advantages

Suitable for a reduced size
Low friction coefficient; no stick-slip effect
Excellent extrusion and wear resistance
Wide temperature range and excellent chemical resistance, depending on the material selected for the O'Ring
