Question by: Clint W on Mar 22, 2026, 9:12 PM

trying to match up a u-seal i pulled out. are the sizes on this one 0.938 OD and 0.6875 ID with a 0.125 height?

Answer by: Customer Support on Mar 24, 2026, 6:45 PM

The key dimensions on this seal are 0.938 inch outside diameter, 0.6875 inch inside diameter, and 0.125 inch height (cross section). If those match what you measured, you are looking at the same size.
