Got a hydraulic cylinder here with a 3.25 bore and need a u-seal that'll hold up past 3,000 PSI. this one gonna cut it?
Question by: Troy E on Mar 28, 2026, 4:45 PM
For a 3.25 inch bore, the inner diameter on this seal matches up right. Pressure-wise, it's rated to handle anywhere from 0 all the way up to 6,000 PSI, so 3,000 PSI sits well within its working range. The polyurethane construction is built for demanding hydraulic service, and the beveled lip design helps it maintain a consistent seal under load. Just confirm your groove dimensions line up with the 3.75 inch OD and 0.38 inch height before you button it up.
