The REDHORSE PERFORMANCE 16AN Flare Plug in black is a single-piece aluminum fitting that seals an unused -16 AN flare port on a fuel, oil, or coolant system. It's built for fabricators, engine builders, and anyone running a custom plumbing setup who needs to cap off a -16 AN female connection cleanly. This is the largest plug in the 806 series, sized for -16 AN (AN-16) hardware, and it ships one per package. The black anodized finish keeps it consistent with matched fitting sets, so a blocked-off port doesn't stand out against the rest of the run.
Redhorse machines the 806 series from aluminum on CNC equipment, then hand-polishes and anodizes each piece. The black finish on the 806-16-2 resists corrosion and holds up against fuel and oil exposure. The plug seats against the 37-degree flare cone standard used across AN plumbing, so it threads into any -16 AN female fitting or hose end and seals on the flare face rather than relying on tape or sealant. The aluminum body keeps weight down compared to steel hardware in the same size, which matters when you're closing out multiple ports across a system. For matched builds, the same finish carries across Redhorse caps, unions, and adapters in the rest of our fittings, hoses and valves selection.
Reach for this plug when you're blocking a -16 AN port on a fuel cell, surge tank, or oil system during a build or a layout change. It pairs naturally with a matching 16 flare cap when you need to seal a male end as well, and with the rest of our 16 union fittings for completing a -16 line run. If you're working in smaller sizes elsewhere on the same project, we stock the same 806 series plugs down through the common AN ranges. Order the size you need and keep your plumbing consistent end to end.
It seals an unused -16 AN female flare port on a fuel, oil, or coolant system. The plug threads into the female fitting and seats against the 37-degree flare cone, blocking the port without tape or thread sealant. Use it when you need to close off a line you're not running.
The REDHORSE PERFORMANCE 806-16-2 ships one plug per package. If you're closing out several -16 AN ports, you'll need to order the quantity that matches your build.
It's machined from aluminum on CNC equipment, then hand polished and anodized black. The aluminum body keeps weight low compared to steel hardware in the same size, and the anodized finish resists corrosion from fuel and oil exposure.
Yes. The plug uses the 37-degree AN flare standard, so it threads into any -16 AN female fitting or hose end and seals on the flare face. That makes it compatible across standard AN plumbing components in the -16 size.
