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

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

The DRTU18-1.75-37 U-Seal is a high-performance rod seal built for demanding hydraulic applications where high pressure, wide temperature range, and wear resistance are critical. Made from 92A urethane, this U-seal is rated for up to 6,000 PSI and 3 ft/sec speeds, helping keep hydraulic fluid where it belongs—inside the cylinder, not providing “free lubrication” to everything around it.
