Description

The BECA 482 profile is a double acting composite wiper seal composed of a filled PTFE friction ring and a pre-tightened rubber O'Ring.

Advantages

Low friction coefficient; no stick-slip effect
Wide temperature range and excellent chemical resistance, depending on the materials selected
Excellent abrasion and wear resistance
Very good wiping effect against external pollutions
