QUALITY & EXPERTISE FOR YOUR SEALING NEEDS



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
