The Style 2700 Polyurethane Piston Seal is engineered for high-performance hydraulic applications, providing reliable sealing in systems with a bore diameter of 3.50 inches and a groove diameter of 2.94 inches. Constructed from a durable glass/PTFE filled polyurethane with a rubber energizer, this seal offers excellent resistance to wear and extrusion under extreme conditions.
Designed to withstand pressures up to 5,000 PSI, this piston seal operates effectively across a temperature range of -40°F to 220°F, making it suitable for demanding industrial environments. Its precise dimensions, including a seal cross-section of 0.087 inches and a seal height of 0.269 inches, ensure a secure fit and optimal performance. The seal's tolerances and material composition contribute to its robustness and longevity in high-pressure applications.
