got a cylinder that takes a u-seal, how do i tell if this one matches up
Question by: Connie R on Apr 27, 2025, 6:43 PM
Fit comes down to the three dimensions: 3.000 inch OD, 2.375 inch ID, and 0.3125 inch height or cross section. If your existing seal or your groove calls for those same numbers, this is the matching size style where height and cross section are equal.
Answer by: Customer Support on Apr 29, 2025, 6:08 AM
Got a 3-inch bore cylinder that needs a new rod seal – this U-seal rated for that kind of pressure, or is it more of a light-duty part?
Question by: Cheryl G on Jan 29, 2026, 2:43 PM
Rated up to 6,000 PSI, it holds its own in heavy-duty hydraulic work without any issues. The 3.00 inch OD and 2.375 inch ID are the key fit dimensions, so as long as your cylinder bore and rod match those numbers, you're in good shape for demanding reciprocating applications.
