BECA 161 - 163 - 165
BECA 161 - 163 - 165
Description
The BECA 161-163-165 profiles are double acting composite rod seals composed of a pre-tightened rubber O'Ring and a custom-made polyurethane friction ring.
Advantages
Optimal sealing in static and dynamic applications
Excellent abrasion and wear resistance
