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

This is a -6AN O-ring boss (ORB) adapter with a 1/8 NPT port on the end, machined from 6061 billet aluminum and hard-anodized black. It lets you tap a pressure gauge or sensor into an ORB port without adding a separate tee, which is its main advantage over a plain AN-to-NPT adapter. The one-piece body and reusable O-ring seal suit fuel, oil and coolant lines on custom builds. It is aimed at fabricators and racers plumbing gauges or senders, not at stock replacement work.

Pros
  • One-piece 6061 billet body resists cracking at the threads
  • Hard-anodized finish holds up to fuel and oil
  • O-ring boss seal is reusable and reseals after removal
  • Compact length fits tight engine bays
  • 1/8 NPT end takes common gauges and senders
  • High flow capacity suits fuel and oil lines
Cons
  • Aluminum threads strip more easily than steel if over-torqued
  • 1/8 NPT is small; not for high-flow sensor ports
  • Anodized coating can scratch during installation
  • O-ring is not always included or spares are hard to find
  • No published torque spec, so you torque by feel

Questions and answers

Will this fit a -6AN hose end?
Yes. The ORB side is -6AN, so it mates with standard -6AN hose ends and ORB ports. The other end is 1/8 NPT for a gauge or sender.
Can I use it for a fuel pressure gauge?
Yes. The 1/8 NPT port takes common fuel pressure gauges and senders. Keep the port small and check that your gauge's thread matches 1/8 NPT.
Is it safe for brake lines?
Aluminum ORB fittings are usually used for fuel, oil and coolant. For brake systems, steel fittings are the safer choice because of pressure and thread strength.
What is included?
The adapter itself. Check whether an O-ring is included before installing, and source a spare if your port needs one.
How tight should I torque it?
No torque spec is published. Tighten the ORB side snug against the O-ring and the NPT side with thread sealant, avoiding over-torque on the aluminum threads.
Does it work with a pressure sensor?
Yes, if the sensor has a 1/8 NPT thread. The compact body keeps the sensor close to the port, which helps in tight engine bays.
