Centering ring assemblies are a critical part of any ISO sealing solution. Centering rings come in both 304 stainless steel and aluminum for 1 x 10-8 Torr high vacuum applications. Centering rings align the two mating flanges during the seal assembly and clamping process as well as providing structural support for the  elastomer sealing ring. 

Within our centering ring offering, IES offers a complete range of O-ring elastomers.

For a detailed look at differences in common elastomers, view the thermal properties of nitrile, silicone, fluoroelastomers, and perfluoroelastomers on page 2.

Thousands of O-rings are in stock and can ship same-day. Shop our website for all O-rings.
