A hex hose finisher for AN4 hose with a 12.8 mm internal diameter, the smallest size in our finisher range. Small-bore braided hose frays readily once cut, and a finisher both stops that and clamps the hose securely onto its spigot. On gauge lines, small breather runs and light fuel plumbing it turns an otherwise scruffy termination into something that looks deliberate and matches the machined fittings used elsewhere. Because the parts are small, take care to seat the hose fully onto the spigot before clamping so the grip is on hose, not on air. Order against the measured outside diameter of your hose over the braid.
