What's the operating temp on this seal? Gotta make sure it can handle the heat where I'm using it.
Question by: Hank R on Feb 2, 2026, 6:19 AM
This polyurethane U-seal can handle temperatures from -65°F up to 220°F, so it should work in a pretty wide range of environments.
Answer by: Customer Support on Feb 3, 2026, 8:12 AM
Seal's rated up to 6,000 PSI, that enough headroom for a standard hydraulic cylinder runnin' reciprocating duty all day?
Question by: Jean M on Oct 20, 2025, 6:05 PM
For most hydraulic cylinder applications running reciprocating strokes, that pressure rating holds up fine. The seal handles 0 to 6,000 PSI, which covers the operating range of a wide range of standard industrial cylinders. The beveled lip design also helps it maintain consistent film breaking under dynamic conditions, so it's not just rated for pressure on paper, the geometry supports actual moving-seal performance.

trying to replace a u-seal i pulled out, do these measurements mean it’s 1.50 OD, about 0.19 ID, and roughly 0.16 tall?
Question by: Rusty E on Sep 10, 2025, 9:53 PM
Fit comes down to matching the seal dimensions. This U-seal is 1.50 inch OD, 0.188 inch ID, and 0.1563 inch height, so it lines up with the 1.50, 0.19, 0.16 sizing you mentioned.
