A hex hose finisher for AN14 hose with a 28.58 mm internal diameter. AN14 is used where flow volume is the priority, on big intercooler, breather and coolant runs, and hose that size relies on a properly distributed clamp load to stay on its spigot. A finisher spreads that load around the full circumference instead of pinching it in one place the way a worm-drive clamp does, which is better for the hose as well as better looking. The hex body then covers the cut braid completely. Order against the measured outside diameter of your hose over the braid, and check the finisher can be reached with a tool once the hose is in its final position.
