Backup ring

For backup rings (T1, T2, T3, etc.), we have Sakura seals in stock for immediate delivery along with O-rings.

The backup ring specified in JIS B2401-4 (formerly JIS B2407 backup ring for O-rings) is an auxiliary material used for O-rings in high-pressure and dynamic applications. At Sakura Seal, we can also manufacture special dimensions beyond those specified by JIS and other standards, so please feel free to contact us.
