got a 1-1/4 inch ORFS fitting that needs a new o-ring, this the right size to grab?

Question by: Hugh M on Mar 10, 2026, 1:52 PM

For a 1.25 inch O-Ring Face Seal fitting, the dimensions here line up correctly. The inside diameter runs 1.176 inches and the outside diameter is 1.316 inches, with a width of 0.07 inches. That matches the standard cross-section for a 1-1/4 inch ORFS application, so you'd be in good shape ordering this one as a replacement.
