T Seal

T Seals are three-piece seals with an elastomeric lip and hard plastic anti-extrusion rings, it is proved to be of long-time service.

T Seals provide excellent sealing solutions for static or reciprocating dynamic applications. They can be designed to be modified into existing O-ring grooves (piston and connecting rod directions) or optimized for specific application requirements.

T Seals are manufactured by machining or moulding made of different HNBR or FKM-types as sealing material and a backup ring made of PEEK.

The design of the T Seal uses the system pressure to actively energize the backup ring to ensure effective resistance to extrusion in unidirectional and bidirectional pressure applications under static and dynamic conditions.

JST STA series T Seal is for piston. STB series T Seal is for rod.
