Product Questions & Answers

got a cylinder that takes a u-cup, are these dimensions 0.75 ID and 1.13 OD with about a 3/16 height?
Question by: Shane H on Sep 20, 2025, 12:02 PM
The seal is sized at 0.75 inch ID and 1.125 inch OD, with a height of 0.1875 inch, which is right around 3/16 inch.

Got a cylinder rod that's 3/4 inch. Will this seal fit up right, or am I looking at the wrong size?
Question by: Janice P on May 31, 2025, 3:20 PM
For a rod seal application, the 0.75 inch inner diameter is what seats against the rod, so a 3/4 inch rod is exactly what this seal is sized for. The outer diameter runs 1.125 inches, so your gland bore needs to match that. Height comes in at 0.1875 inches. As long as those gland dimensions line up, you're in good shape.

Reckon this'd be alright for a hydraulic jack I'm fixin' up?
Question by: Dwayne F on Nov 22, 2025, 3:48 PM
This U-seal should work in systems pushing up to 6,000 PSI and where the temperature stays between -65°F and 220°F.
