The T-seal comes in both piston (TPO) and rod (TRO) styles, and can be installed in standard O-ring grooves. The T-seal is a double acting seal. The Back-up rings and sturdy base help prevent extrusion and spiralling up to 5,000 PSI. Standard T-seals are composed of a Nitrile sealing element and two Nylon Back-up rings. A popular combination for added chemical resistance is our Viton® and PEEK T-seal.
T-Seals are also used in piston caps and pulser poppet tips and fit OEM design specs.
