A hex hose finisher for AN6 hose with a 16.0 mm internal diameter, and the size most people need first. AN6 is the default for fuel, oil and coolant plumbing on the majority of builds, so this is the finisher that turns up most often in a parts list. It clamps the hose securely onto its spigot with an even, all-round grip and hides the cut braid inside a hex body that looks like the machined hose ends used elsewhere in the system. Buy against the measured outside diameter of your hose over the braid rather than assuming it from the AN number, as constructions vary between hose types.
