AN ORB to female 1/8" NPT adapter fitting engineered by Radium Engineering for fuel system and sensor applications. This precision-machined adapter converts AN ORB (O-Ring Boss) ports to female 1/8" NPT threads, allowing installation of sensors, gauges, or other NPT-threaded components.
Ideal for installing sensors or gauges in fuel rails, surge tanks, fuel pressure regulators, and other automotive applications. Perfect for motorsport, track, or high-performance street builds where sensor or gauge installation is required in AN ORB ports.
Important Notes: NPT (National Pipe Thread) fittings seal by the intentional interference created by the tapered threads meshing together. Always use a small amount of PTFE paste or tape on NPT threads and tighten to finger tight, then add another 1.5 to 3 turns until tight.
