Engineered for demanding hydraulic piston applications, this T-Seal delivers reliable bi-directional sealing in dynamic environments where standard O-rings fall short. The T-shaped cross-section — combined with anti-extrusion back-up rings — eliminates the spiral failure and extrusion common in high-pressure reciprocating cylinders, giving your system the leak-free performance it demands.
Key Benefits
Bi-directional sealing eliminates the need for dual-seal configurations
Integrated back-up ring grooves prevent extrusion at elevated pressures
Excellent resistance to petroleum-based hydraulic fluids, oils, and fuels
Low friction profile reduces stick-slip and extends cylinder service life
Dimensionally stable across a wide temperature range
