Question by: Ronnie T on Dec 25, 2025, 8:28 PM
i’ve got a groove that takes a -224 o-ring, is this the same dash size?
Answer by: Customer Support on Dec 27, 2025, 8:39 AM
Match it up by dash size and this one is a -224 (SKU A-224). It is a 70 durometer Buna-N ring with a nominal 1-3/4 inch ID and 2 inch OD, and the actual measured sizes are 1.734 inch ID and 2.012 inch OD.
