seal's rated up to 6,000 PSI, that gonna hold up running a hydraulic cylinder pretty much all day on a press?
Question by: Bonnie R on Nov 11, 2025, 11:05 AM
Polyurethane handles sustained pressure well, and 6,000 PSI is the rated upper limit for this seal. The beveled lip design helps maintain a consistent fluid film rather than letting pressure blow past the sealing surface, which matters a lot on equipment that runs for long stretches. That said, keeping your system within the rated range and making sure the bore and rod dimensions match the 0.875 inch OD and 0.625 inch ID is what's really going to determine how long it holds up in continuous-duty use.

i got a groove that measures right at 5/8 on the shaft and 7/8 on the bore, is this u-seal the right size
Question by: Ray C on Jun 17, 2025, 1:25 PM
The key dimensions on this seal are 0.625 inch ID and 0.875 inch OD, with a 0.125 inch height and 0.125 inch cross section. If your shaft is 5/8 inch and your bore is 7/8 inch, those numbers line up with the seal’s listed ID and OD.
