U-Seal, 2"X2-3/8"X5/16"

U-Seal, 2"X2-3/8"X5/16"

The DRTU18-2.00-31 U-Seal (2" x 2-3/8" x 5/16") is a high-performance hydraulic rod seal engineered for long life and reliable sealing in dynamic applications. Designed with a secondary internal lip, this seal helps reduce leakage while preventing air and contaminants from entering the cylinder. Manufactured from 92A urethane, it offers excellent durability, stability, and wear resistance while maintaining low friction for smooth rod movement. Built for demanding hydraulic systems, it performs reliably under high pressure and a wide temperature range.
