O-ring 79,77x5,33 FPM80 BROWN

This O-ring with dimensions 79.77 × 5.33 mm is made of fluorocarbon rubber (FPM/FKM) with a hardness of 80 Shore A. The cross-section profile is circular — standard for O-ring seals — ensuring uniform contact pressure against the sealing surfaces. The brown colour is characteristic of FPM material and has no effect on functional properties. The seal complies with DIN 3771.

Fluorocarbon rubber (FPM/FKM) offers resistance to mineral oils, fuels, hydraulic fluids, acids and oxidising substances. The material maintains its sealing properties across a wide temperature range. It is used in both static and dynamic sealing applications in hydraulic, pneumatic, automotive and chemical industries.
