BECA 151 - 153 - 155
Description
The BECA 151 - 153 - 155 profiles are double acting composite rod seals composed of a virgin or filled PTFE friction ring and pre-tightened rubber O'Ring.
Advantages
Optimal sealing in static and dynamic applications
Low friction coefficient; no stick-slip effect
Excellent abrasion resistance
Wide temperature range and excellent chemical resistance, depending on the material selected for the O'Ring
