SpeedFactory Racing -16 AN Black Anodized Hose End Fittings

SpeedFactory -16AN Black Anodized Hose End Fittings

Dash 16 is coolant territory. If you're plumbing a race radiator, a coolant reroute, or a water pump housing delete, this is the line size that job runs on, and these are SpeedFactory's black anodized aluminum hose ends for it. Sold individually in straight and 45 degree.

What It Is and Why It Works

These are machined aluminum hose ends with a black anodized finish and a swivel design, which is the part that matters when you're actually building lines. A swivel lets the fitting rotate on the hose end as you tighten it, so you can clock the AN nut to your port without twisting the hose or fighting the assembly into position. On a stiff -16 line that's the difference between a clean install and a hose that's under load before the engine even runs.

Anodizing does two jobs here beyond looking right: it hardens the surface so the wrench flats survive assembly, and it slows corrosion on aluminum that's going to live in an engine bay with coolant running through it.

Available Options

Fitment

Universal. These thread to any -16AN port and assemble onto -16AN hose, so what determines your order is the plumbing layout, not the car. On Honda builds, -16 typically shows up in cooling: race radiator inlet and outlet, coolant rerouting, and water pump housing deletes that use a -16AN ORB water inlet.

Fuel systems generally live at -6, -8, or -10, so if you're plumbing fuel, you're looking at the wrong size on this page.

What to Know Before You Buy

Count before you order. Every hose needs a fitting on both ends, so a single line is two fittings, and a radiator inlet and outlet is four. These are sold individually and it's easy to underbuy. If you're doing an entire radiator setup from scratch, check SpeedFactory's -16AN hose and fitting kits first, since a complete kit usually costs less than sourcing every piece separately.

Match your hose to your fittings. AN hose ends are built around a specific hose construction, so buy the hose and the ends as a set rather than mixing brands and hoping the barb and ferrule geometry lines up. Reach out if you're unsure what pairs with these.

Use AN wrenches, not adjustables. Anodized aluminum flats mar the first time a crescent wrench slips, and a chewed-up fitting on a coolant line is one you'll end up replacing. Cut the hose square, deburr it, and use assembly lube when you thread the nut on; aluminum threads gall quickly if you force them dry.
