Piston and Rod T-seals

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. The standard design will fit into an O-ring gland and can be machined or net moulded.

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.

We produce customizable T-seals from a variety of materials to meet almost any gland size. 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 use of backup rings allows T-seals to be used in high-pressure applications while maintaining high sealing efficiency at low pressure. 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.

Due to the symmetrical geometry of T-seals, the installation procedure is usually simpler than other seal designs.
