U-Seal, 1.25"X1.62"X5/16"

U-Seal, 1.25"X1.62"X5/16"

The DRTU18-1.25-31 U-Seal is a high-performance rod seal designed for demanding hydraulic applications where pressure, temperature range, and wear resistance matter. Made from 92A urethane, this U-seal handles up to 6,000 PSI and operates across a wide -65°F to +230°F range, making it a tough, dependable choice for keeping fluid where it belongs—inside the cylinder, not decorating your shop floor.
