This REDHORSE PERFORMANCE 8AN male to 3/8 pipe thread male adapter routes a fuel, oil, or coolant line around tight engine bay obstructions with a built-in 45-degree bend. It connects an 8AN flare line to a 3/8-inch tapered pipe port, making it a common bridge between aftermarket plumbing and stock or modified components. Builders working on fuel rails, oil cooler loops, and breather setups reach for adapters like this when a straight fitting won't clear a valve cover or frame rail. You'll find the full range of AN adapters in our catalog alongside this part.
The 45-degree angle is the defining feature here. It lets a hose end exit the port at a controlled angle instead of forcing a sharp bend in the line itself, which protects flow and reduces strain on braided hose. The 8AN side uses the standard 37-degree flare seat that every AN fitting shares, so it mates cleanly to AN hose ends and unions without thread sealant. The 3/8-inch pipe thread side seats into a tapered female port and should be installed with a thread sealant rated for fuel. Machined from aluminum and finished in blue anodize, the body resists corrosion and shrugs off the underhood environment. Carries MPN 823-08-06-1 and UPC 810465013770 for exact reordering.
Reach for this adapter when you're plumbing an 8AN line into a 3/8-inch pipe port and need the line to turn without kinking. It suits fuel system builds, oil cooler and remote filter setups, and any custom loop where clearance is tight. Pair it with matching 8AN straight hose ends and braided line for a complete run, or browse our full fittings, hoses, and valves selection to spec the rest of the system. If you need a different angle or port size, the REDHORSE PERFORMANCE line covers most common combinations.
It joins an 8AN flare line to a 3/8-inch tapered pipe port. The 8AN end uses the standard 37-degree AN flare seat, while the pipe thread end threads into a female port. The 45-degree bend lets the line exit at an angle to clear tight spaces.
The 8AN flare side seals on its 37-degree flare and needs no sealant. The 3/8-inch pipe thread side uses a tapered thread that seats by interference, so apply a fuel-rated thread sealant or PTFE paste on that end to ensure a leak-free joint.
It is machined from aluminum and finished in blue anodize. Anodizing adds a hard, corrosion-resistant surface that holds up to fuel, oil, and the heat and moisture of an engine bay while keeping the fitting lightweight at about 0.07 lbs.
The 45-degree bend routes the hose around obstructions like valve covers and frame rails without forcing a sharp kink in the braided line. That protects flow and reduces stress on the hose end, which matters in tight engine bay plumbing.
