Reckon this'll hold up in a hydraulic system pushing close to that 6,000 PSI max?
Question by: Clint H on Sep 14, 2025, 4:45 PM
This U-seal is rated to handle pressures from 0 up to 6,000 PSI, so it should work for your system if it's close to that maximum.
Answer by: Customer Support on Sep 16, 2025, 7:38 AM
seal's rated up to 6,000 PSI, that hold true running continuous hydraulic pressure or just peak spikes?
Question by: Wade M on Feb 4, 2026, 8:22 AM
Urethane handles that pressure range across continuous operation, not just momentary spikes. The 0 to 6,000 PSI rating reflects what the material and geometry are built to sustain under load. The beveled lip design plays into this too, since it maintains film across the sealing surface rather than breaking down under sustained pressure. For most hydraulic cylinder applications running steady system pressure, this seal holds up through the full range.

got a gland that takes a 2.50" ID seal, is this one the right size if my bore is 3.50"?
Question by: Ricky B on Jul 28, 2025, 8:49 AM
Fit comes down to the seal’s measured sizes. This U-seal has a 2.50 inch inner diameter, 3.50 inch outer diameter, and 0.50 inch height, so it matches a setup calling for those exact dimensions.
