U-Seal, 2-1/4"X2-3/4"X3/8"

U-Seal, 2-1/4"X2-3/4"X3/8"

The DRTU25-2.25-37 U-Seal is a 92A urethane U-seal sized for 2-1/4" rod applications, built to handle demanding hydraulic sealing with pressure capability up to 6,000 PSI and temperatures from -65°F to +230°F. With a 3 ft/sec speed rating and defined extrusion-gap limits by pressure, it’s a serious seal for serious work—because leaks are only acceptable when you’re telling tall tales.
