Got a 2-inch rod on a hydraulic cylinder and need a U-seal that'll hold up to some real pressure. This one rated high enough for that kind of work?
Question by: Ray P on Dec 31, 2025, 10:24 AM
For a 2-inch rod application, the ID on this seal is exactly 2.00 inches, and the OD comes in at 2.375 inches, so the fit lines up with standard bore and rod dimensions in that range. Pressure-wise, it's rated up to 6,000 PSI, which covers most demanding reciprocating cylinder work without any issue. The urethane construction handles both fluid containment and wear resistance well in dynamic environments, so it holds up where cheaper materials tend to fail early.

What kind of pressure can this handle without blowing out?
Question by: Kirk W on Apr 6, 2026, 9:46 AM
This U-seal is rated to handle pressures up to 6,000 PSI, so it should hold up well in demanding hydraulic applications.

got a cylinder groove set up for a 2 inch rod. is this u-seal the right size or am i lookin at the wrong one
Question by: Cindy M on Apr 9, 2025, 6:17 PM
Fit comes down to the seal dimensions. This urethane U-seal is 2.00 inch ID, 2.375 inch OD, with a 0.1875 inch height and cross section in the SQB style. If your setup calls for a 2.00 inch ID U-seal and has room for a 2.375 inch OD, it matches those sizes.
