seal's rated up to 6,000 PSI -- that cover most standard hydraulic cylinder work or is that more of a ceiling you'd rarely hit in normal shop use?
Question by: Steve R on Oct 8, 2025, 6:53 PM
For most hydraulic cylinder applications you'd run into on industrial or mobile equipment, pressures stay well under 6,000 PSI, so this seal has plenty of headroom. That upper rating is genuinely useful in high-pressure circuits, but even in moderate-duty systems running 1,500 to 3,000 PSI, the urethane construction holds up well against extrusion and wear during pressure cycling. The beveled lip keeps good film contact on the rod or piston surface across that whole range, not just at the high end.

got a small gland, is this u-seal the deep style or the regular one?
Question by: Frank M on Dec 10, 2025, 2:37 PM
Height is 0.25 inch with a 0.125 inch cross section, so it falls into the deep type group where the height is greater than the cross section.

What kinda pressure can this lil' fella handle?
Question by: Pete P on Dec 13, 2025, 3:50 PM
This U-seal is rated to handle pressures from 0 up to 6,000 PSI, making it suitable for demanding hydraulic applications.
