The Vibrant Performance 10716 is a -16AN 45 degree union adapter that joins two female AN flare ends, making it the fitting you reach for when a plumbing run needs to change direction at a fixed angle. This is the 45 coupler -16AN female to female piece used in custom fuel, oil, and coolant routing on modified street cars and dedicated race builds. It threads directly to male AN hose ends and hard-line fittings, so it drops into an existing -16AN system without adapters. Fabricators building turbo, LS swap, and high-flow fuel setups use these unions to keep clean angles where space is tight. Browse the full adapter lineup for related sizes.
Vibrant Performance machines the 10716 from 6061 aluminum alloy and finishes it in black anodize, per manufacturer specifications. The 6061 alloy holds thread integrity under the pressures seen in fuel and oil systems while keeping weight low, and the anodized coating resists corrosion from pump fuel, ethanol blends, and synthetic oils. Both ends carry female -16AN flare threads with the standard 37 degree seat, so they seal metal-to-metal against male hose ends without sealant or thread tape. The fixed 45 degree bend lets you route a -16AN line around an obstruction without forcing the hose into a tight radius. It carries a one year limited warranty. Pair it with -16AN hose ends and 16-size unions to complete a run.
Reach for the 10716 when a -16AN feed or return line has to turn 45 degrees between two components such as a fuel pump, surge tank, oil cooler, or filter housing. Because both ports are female, it mates directly to two male AN hose ends, letting you build a midline angle without a swivel or a second adapter. -16AN is a large-bore size built for high-volume fuel and oil flow, so this fitting belongs in serious systems rather than light-duty plumbing. See our full fittings, hoses and valves selection and matching swivel fittings to finish the build.
It joins two female -16AN flare ends at a fixed 45 degree angle. Each port threads onto a male AN hose end or hard-line fitting, so it creates a directional change in the middle of a -16AN line without needing extra adapters.
No. The 10716 uses the standard 37 degree AN flare seat, which seals metal-to-metal against the cone of a male AN fitting. Sealant or PTFE tape on AN flare threads can interfere with the seal and should not be used here.
Vibrant Performance machines it from 6061 aluminum alloy with a black anodized finish. The alloy handles the pressure of fuel and oil systems while staying light, and the anodizing resists corrosion from pump fuel, ethanol blends, and synthetic oils.
-16AN is a large-bore size used for high-volume fuel and oil flow, common on forced-induction and high-horsepower builds that move a lot of fluid. For lighter-duty plumbing, smaller AN sizes are usually the better match.
Yes. Both ports are female -16AN flare, making it a 45 degree female-to-female union. It mates to two male AN hose ends rather than to other female fittings.
