Got a piece of equipment that calls for a 4-1/2 inch ID o-ring in the 3/32 nominal width. This the right fit?
Question by: Carl B on Dec 30, 2025, 1:15 PM
For a nominal 4-1/2 inch ID with a 3/32 nominal width, yes, this is the one. Actual dimensions come in at 4.487 inches on the inside diameter and 4.693 on the outside, with an actual width of 0.103 inches. Buna-N at 70 durometer is the material, so it'll hold up well in hydraulic systems exposed to oils and fuels. Dash size is -157 if you need to cross-reference it on your end.
