U-Seal, 1-3/4"X2-1/8"X5/16"

U-Seal, 1-3/4"X2-1/8"X5/16"

This U-Seal is a high-pressure 92A urethane sealing solution sized 1-3/4" x 2-1/8" x 5/16", engineered to perform in demanding hydraulic applications up to 6,000 PSI. With a wide -65° to +230°F operating range and controlled extrusion characteristics, it’s built to keep things sealed tight when conditions (and pressure) refuse to behave.
