The Vibrant Performance -8AN Male to M14x1.5 Female Flare Adapter mates a standard -8AN hose end to an M14x1.5 metric port, giving engine builders a clean way to tie AN-spec plumbing into factory or aftermarket components that use metric threads. It's a common need on diesel fuel systems, oil cooler lines, and coolant routing where the OEM port is metric but the rest of the build runs AN. This adapter handles that crossover without a stack of intermediate pieces. If you're sorting through adapter fittings for a custom plumbing job, this is the piece that bridges those two thread standards.
The -8AN side uses a 37-degree flare seat, which seals against the matching cone on a -8AN hose end without thread sealant or tape — the metal-to-metal flare does the work. The M14x1.5 female end threads onto a male metric stud or fitting, matching the 14mm diameter and 1.5mm pitch found on a wide range of import and diesel engine ports. Overall length runs about 1 inch per manufacturer specifications, keeping the connection compact in tight engine-bay routing. Carry it on a -8AN hose run and you keep the full flow of the line, since the bore is sized to the -8 standard rather than choked down at the transition. Pair it with the right braided hose and hose ends for a complete assembly.
Reach for this adapter when a build calls for -8AN hose but the component port is M14x1.5 — turbo oil feeds and returns, fuel pressure regulator ports, and oil cooler sandwich plates are typical spots. It saves you from running a banjo bolt or a reducer chain where a single fitting will do. Keep a couple on the bench if you build with metric-port hardware regularly. When you're ready to finish the run, browse our full fittings, hoses, and valves selection along with matching -8 straight hose ends to complete the line.
It joins a -8AN male flare fitting on one end to an M14x1.5 female metric thread on the other. That lets you connect AN-spec hose ends to engine components built with 14mm by 1.5mm pitch metric ports, common on diesel and import fuel, oil, and coolant systems.
No. The -8AN end uses a 37-degree flare that seals metal-to-metal against the matching cone on a -8AN hose end. The seal comes from the flare seat itself, not the threads, so no tape or liquid sealant is required on that connection.
The female end matches an M14x1.5 male thread — 14mm outer diameter with a 1.5mm thread pitch. Confirm your component port uses that exact size and pitch before ordering, since metric ports come in several diameters and pitches that look similar.
Any standard -8AN hose end with a 37-degree flare will mate to this adapter. Match it to a -8 braided or PTFE hose assembly sized for your fuel, oil, or coolant application for a full-flow connection.
