Question by: Steve T on Sep 2, 2025, 3:17 PM

trying to swap out a worn seal, are these measurements OD 1.50, ID 1.00, height 0.25 the ones i need to match?

Answer by: Customer Support on Sep 4, 2025, 6:34 AM

Match all three dimensions: 1.50 inch outer diameter, 1.00 inch inner diameter, and 0.25 inch height. On this U-seal the height and cross section are the same at 0.25 inch, so that 0.25 measurement matters just as much as the ID and OD.
