U-Seal, 1-1/2"X1-7/8"X1/4"

The DRTU18-1.50-25 rod seal is a high-pressure urethane sealing solution designed for hydraulic applications where you need tight sealing, strong wear resistance, and dependable performance under serious load. Made from 92A urethane, it’s built to handle up to 6,000 PSI and rod speeds up to 3 ft/sec, with a wide operating temperature range from -65°F to +230°F. In other words: it’s the kind of seal that shows up, does the job, and doesn’t ask for applause.

Ideal For

• Hydraulic cylinders needing a urethane rod seal with strong wear resistance
• Systems operating up to 6,000 PSI
• Applications with rod speeds up to 3 ft/sec
• Equipment exposed to wide temperature swings (-65°F to +230°F)
• Builds where controlling extrusion gap matters—because “seal squish-out” is not a maintenance strategy
