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

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

The DRTU25-1.75-37 U-Seal is a high-performance urethane U-cup seal built for demanding hydraulic applications where pressure and temperature swings are part of the job. Made from 92A urethane, it’s rated up to 6,000 PSI and operates from -65°F to +230°F, with a 1-3/4" ID, 2-1/4" OD, and 3/8" height for precise fit in the proper gland—because seals only get one job, and they should do it without drama.
