Tube to Female AN Adapter

Where the hardline ends, the AN system begins, and this is the fitting at the border.

Hardline runs still need to meet hoses, pumps, and rails. The Finish Line Factory Tube to Female AN Adapter is the border crossing: a flared-tube connection for 1/2 Tube, 1/4 Tube, 3/4 Tube, 3/8 Tube, 5/16 Tube, 5/8 Tube tube on one side, a female AN swivel in 4AN, 6AN, 8AN, 10AN, 12AN on the other. CNC machined from lightweight 6061 aluminum, anodized black, with high-quality sealing for volatile fuels. Tube to AN, one fitting.

Benefits

• The hardline run terminates in a normal, serviceable AN connection
• Tube flares draw into the seat evenly with the matching nut and sleeve
• The swivel nut lands on a male flare without rotating the tube run
• The mixed hardline-and-hose system reads as one designed circuit

The Details

The tube side seals on the tube's own flare, drawn in by its nut over its sleeve, so flare quality decides the joint: even, uncracked, fully formed. The AN side seals dry on the 37 degree cone as always. A female swivel here lets the fitting mate to a fixed male flare, pump outlet, or rail fitting without twisting the finished hardline, which cannot twist. Best practice puts a short hose section between hardline and anything that moves, letting the tube do distance and the hose do motion. Back the fitting while torquing either side so the two joints never fight each other.
