TPE 55D Piston Seal 2.500" ID X 2.106" OD X 0.115" HT

Get a dependable hydraulic seal that installs quickly and performs without leakage. This 1704 series piston seal is built for consistent sealing in hydraulic cylinders where downtime is not an option. The compact square cap design helps prevent hydroplaning and maintains sealing contact across a wide range of pressures.

Made from TPE HT2022 (Hytrel) at 55 Durometer D in black, this seal delivers strong mechanical strength, excellent wear resistance, and very low compression set. The result is longer service life, fewer replacements, and more reliable equipment performance.

Operating temperature: -65° to +275°F (-54° to +135°C)
