T-seals offer an excellent sealing solution for static or reciprocating dynamic applications. T-seals can be designed to retro fit into existing O-ring grooves (both piston and rod orientations) or optimized for specific application requirements.
T-seals comprise of an elastomer T-shaped cross section and two backup rings made from an engineering grade plastic, often PTFE or PEEK.
The use of the backup rings allows the T-seal to be used in high pressure applications whilst still maintaining high sealing efficiency at low pressures. The design of the T-seal uses the system pressure to actively energize the backup rings, ensuring efficient extrusion resistance in single and bi-directional pressure applications, both in static and dynamic conditions.
Installation procedures for T-seals are often simplified over other seal designs due to their symmetrical geometry.
As an alternative to T-seals, PPE also manufactures spring seals (sometimes referred to as all-in-one T-seals).
