The dimensions has an inner diameter of 70 mm, an outer diameter of 80 mm and a height of 2 mm.

About the sealing profile BAC401

BAC401 back-up rings are sealing elements that are generally used behind the o-ring in order to ensure system security and minimize extrusion gaps in many applications.

About the material POM

Polyacetal (POM) (Polyoxymethylene) materials are used as back-up rings or guidening element materials in hydraulic and pneumatic systems. There are two types of POM, filled with or without fibreglass, depending on their use. Despite working temperatures ranging from -40°C to +140°C, real dimensions can not remain stable in excess of 100°C. It can be used safely with mineral oils and HFA, HFB type oils. Types with added fibreglass provide longer lasting contact pressure resistance.
