Nitrile 90 Back-Up Rings BS425 To BS475

£2.0431£18.7696

Back-up rings should generally be used for dynamic applications over 100 bar, and static applications around 950 bar. Each application can vary, therefore it is essential to use this as a general guideline only

Traditionally PTFE has been used but in recent years, contoured elastomer rings have been developed and are now widely used. Eastern Seals supplies a wide range of back-up ring profiles and materials to complement each seal type and to suit every application. We hold large stocks of Contoured rings in both Nitrile and Viton®.
