Description

The BECA 002/5 profile is a 5-part chevron seal. This sealing system is composed of 2 textile-reinforced rubber seals and 1 rubber ring. Its geometry means that it is encapsulated between a head nut and a locking ring.

Advantages

Strong sealing, tolerant to surface roughness defects (impacts on the rod, carbon deposits, etc.)
The tightness can be adjusted depending on the application
Excellent resistance to pressure
