AN Female to AN Male with 1/8" NPT Port Adapter

Every build eventually needs one more sensor, and drilling the tank is the wrong answer.

Gauges, senders, and reference feeds all want a port the system never planned for. The Finish Line Factory AN Female to AN Male with 1/8" NPT Port Adapter adds one inline: a female AN swivel to male AN pass-through in 3AN, 4AN, 6AN, 8AN, 10AN, 12AN, 16AN, CNC machined from high-quality 6061 aluminum, with a 1/8" NPT side port. Tap the line for pressure, temperature, or a feed without touching the tank or rail.

Benefits

• A sensor port appears mid-line in one fitting swap
• The NPT port aims where the sender and its wiring can actually live
• Flare joints seat with the same solid stop as any AN connection
• No drilling, welding, or bung installation to get a reading

Features

• CNC machined 6061 aluminum
• Female AN swivel one end, male AN the other, sizes 3AN, 4AN, 6AN, 8AN, 10AN, 12AN, 16AN
• 1/8" NPT female side port for sensors and feeds
• Straight-through main flow path
• 37 degree flare sealing on the AN connections; tapered thread sealing at the port
• Sold as a single fitting

The Details

Inline port fittings put the measurement where it means something: fuel pressure read at the rail inlet, oil temperature in the actual flow, a clean tap for a boost or vacuum feed. Seals metal to metal on the 37 degree AN flare, no sealant, no tape, ever. The 1/8" NPT port, by contrast, is a tapered joint and wants sealant on the sender threads, applied off the lead thread so nothing sheds into the system. Plug the port with an NPT plug if the sensor comes later; the fitting still earns its place as plumbing. Back the body with a wrench while torquing hose ends and again while torquing the sender, because the port thread should never react assembly loads.
