Our take on the AlloyWorks ORB O Ring Boss Adapter AN Fitting with 1/8 NPT on End Black

This is a one-piece adapter that joins a -6AN O-ring boss port to a 1/8 NPT thread, machined from T6061 billet aluminum with a hard-anodized black finish. The ORB end seals with an O-ring against a port face, while the 1/8 NPT end takes pressure gauges, sensors or small fittings. It suits fuel, oil and coolant plumbing on modified cars where a gauge or sensor needs a clean AN-based takeoff. Against generic brass or cast adapters it offers lighter weight and better corrosion resistance, but it is a single-purpose part, not a swivel or a hose end.

Questions and answers

What does this adapter connect?
It joins a -6AN O-ring boss port to a 1/8 NPT female or male thread, depending on the variant. That makes it a common way to mount a pressure gauge or sensor on an AN line.
Will it fit my -6AN hose end?
The AN side is -6AN, so it mates with standard -6AN hose ends and adapters. The ORB end needs a matching port with an O-ring seat.
Is it safe for fuel and oil?
Yes. Billet aluminum with a hard-anodized finish is widely used for fuel, oil and coolant plumbing. Check the O-ring material matches your fluid, especially with ethanol fuels.
Does it come with an O-ring?
The listing does not state that an O-ring is included. Buy a fuel-compatible O-ring for the ORB side if yours does not come with one.
Can I use it for a pressure gauge?
Yes, a 1/8 NPT gauge or sensor threads straight in. Use thread sealant on the NPT side only, never on the O-ring side.
How tight should I torque it?
Snug the ORB end against its O-ring seat without over-tightening, since aluminum threads strip more easily than steel. Follow your gauge or sensor maker's torque spec for the NPT side.
