Mating Rings/Seals

Mating rings, as their name implies, contact the opposing seal face to form the Primary Interface of the sealing assembly. Unlike the seal with its floating, spring-loaded face, the mating ring is a simple, mostly monolithic ring with a precision lapped flat face. The mating ring is normally sealed in its position by a secondary seal, typically an elastomer. Ettem catalogue Mating Rings are available in metric as well as imperial size range from 25mm (1″) to 100mm (4″) and are offered in standard or special materials. Pressure and temperature limits of mating rings typically equal or exceed the seal’s and therefore are not specified.
