U-Seal, 1.37X1.75X5/16

U-Seal, 1.37X1.75X5/16

The DRTU18-1.37-31 U-Seal is a high-pressure 92A urethane rod seal built for hydraulic applications that demand tight sealing, strong wear resistance, and reliable extrusion control. Rated up to 6,000 PSI and 3 ft/sec, it’s designed to perform under serious load while maintaining stability in the groove—because the seal should handle the pressure, not you.
