Style 1400 Glass-Filled PTFE Piston Seal, 2.25 Inch Bore Diameter, 1.86 Inch Groove Diameter, Inch Groove Width

Description & Features

Designed for hydraulic cylinders operating at pressures up to 5,000 PSI, the Style 1400 Glass-Filled PTFE Piston Seal combines a 15% glass-filled PTFE sealing element with a rubber energizer to maintain consistent contact and sealing force across a wide range of conditions. The glass fill improves wear resistance and dimensional stability compared to unfilled PTFE, making this seal well-suited for demanding reciprocating piston applications.

This seal fits a 2.25-inch bore diameter with a piston diameter of 2.246 inches and a groove diameter of 1.858 inches. The operating temperature range spans -40°F to 220°F, supporting use in both cold-start and elevated-temperature hydraulic systems. Manufactured by Hercules Sealing Products under catalog number C1DH47.
