Product Questions & Answers

Got a cylinder rod that's 5.50 inches across, this u-seal rated to handle serious pressure, or is it more of a light-duty thing?
Question by: Melvin S on Jul 12, 2025, 8:31 AM
For high-pressure work, this seal holds up well. It's rated from 0 all the way to 6,000 PSI, so it's built for demanding hydraulic systems, not just light service. The urethane construction gives it good durability under load, and the beveled lip helps it maintain a clean seal rather than just sitting against the bore passively. As long as your groove matches the 6.00 inch OD, 5.50 inch ID, and 0.56 inch height, you're working with a seal that can handle real industrial conditions.
