Our stainless steel flame arrestors are heavy duty in construction and are hand polished to a mirror like finish (we even polish the button head bolts that are used in their assembly). The arrestors feature course stainless steel mesh for optimum air flow and fit Holley Dominator carburetors. They come complete with two 5/8" breather tubes and meet all U.S. Coast Guard requirements. 10” diameter and 3” tall.
