What kinda pressure can this seal handle before it gives out?
Question by: Larry H on Nov 7, 2025, 8:43 AM
Rated to handle pressures from 0 up to 6,000 PSI, this U-seal should hold up well in most hydraulic applications within that range.

Got a cylinder bore of 5 inch and need a u-seal to fit it, this the right size?
Question by: Keith B on May 8, 2025, 9:34 AM
For a 5.00 inch bore, the ID on this seal matches up exactly. The OD comes out to 5.50 inches with a 0.25 inch cross section, so it sits in a standard gland groove cut for those dimensions. Polyurethane holds up well in hydraulic cylinders where you need consistent sealing pressure without a lot of maintenance fuss.

trying to replace a u-seal i pulled out, are these dimensions 5.00 id and 5.50 od with a 1/4 tall cross section?
Question by: Pete W on Jul 5, 2025, 6:39 AM
Fit comes down to the three size callouts. This urethane U-seal is 5.00 inch ID, 5.50 inch OD, and 0.25 inch height with a 0.25 inch cross section.
