Piston Seal, 1.750X0.109

Piston Seal, 1.750X0.109

The PS1500-28 Piston Seal is a high-performance polyurethane piston seal assembly engineered for hydraulic applications up to 5,000 PSI. Molded from tough 60 Shore D durometer polyurethane, this seal features a .002" molybdenum-filled outer band to help reduce friction and improve wear resistance. Designed to stretch easily over the piston and recover quickly, it eliminates the “cold flow” characteristics common with PTFE seals—delivering dependable sealing performance under pressure.
