got an old o-ring marked A-137, is this the same size or am i fixin to order the wrong one

Match it up by the cross references. SKU 568-137 lists alternate part numbers A-137, C1CD94, MI-08740376, and MINO-00407X90376, so it is the same O-ring size when you are replacing one of those numbers.

got a piece of equipment that takes a 2-1/4 outside diameter o-ring with a 3/32 width, this the right one?

Question by: Brent H on Feb 22, 2026, 4:18 PM

those numbers line up. The actual outside diameter on this one measures 2.26 inches and the actual width comes in at 0.10 inches, which is right in line with a 3/32 nominal width. The actual inside diameter is 2.05 inches, with a nominal inside diameter of 2-1/16. If your equipment calls out those nominal dimensions, this ring should fit right in.
