Description

The BECA 002/7 profile is a 7-part chevron seal and is composed of 3 textile-reinforced rubber seals and 2 rubber rings. 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
