BECA 003

Hydraulic seals / Piston seals

BECA 003

Description

The BECA 003 profile is a 3-part chevron seal in which the central part, which is made of textile-reinforced NBR, is encapsulated between a POM head nut and a TPE locking ring.

Advantages

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