The Vibrant Performance -4AN Female to -4AN Male 45 Degree Swivel Adapter (MPN 10771) is a fluid-delivery fitting built for builders routing fuel and oil lines through tight engine bays. It bridges a -4AN female port to a -4AN male connection while introducing a fixed 45-degree offset, so you can change line direction without kinking hose or fighting clearance against a header, frame rail, or pump body. The swivel design lets the female end rotate during assembly, which means you can tighten the connection without twisting the attached braided hose. It works in naturally aspirated and forced induction setups alike.
This adapter is machined from 6061 aluminum alloy and finished in anodized black, keeping it light and corrosion-resistant for under-hood service. The anti-leak seal design at the AN flare maintains a clean connection under fuel and oil pressure, and the smooth internal bore supports steady flow without the turbulence a sharp bend would create. The female swivel end seats against the mating hose end on the 37-degree AN flare, while the 45-degree body redirects the line cleanly. It connects directly to oil pumps, fuel pumps, fuel filters, and other -4AN-terminated components. For other angled connections in the same size range, the dedicated swivel fitting and adapter categories carry matching options.
Reach for this 45-degree swivel when a straight or 90-degree fitting won't fit the space and you need a clean line route to a regulator, fuel rail, or oil cooler. It pairs with -4AN hose ends, unions, and tube nuts to complete a system without forcing hose into a tight radius. Builders working fuel systems, brake plumbing, or oil lines on race and street builds use these adapters to keep runs tidy and serviceable. Browse the full fittings, hoses, and valves selection at TSA to match hose ends, caps, and plugs to the rest of your -4AN setup.
The female end rotates freely, so you can tighten the connection to your hose end without twisting or binding the attached braided line. That makes routing and final assembly easier in tight engine bays and lets you orient the 45-degree bend exactly where you need it.
It is machined from 6061 aluminum alloy with an anodized black finish, per the available product specifications. The aluminum keeps weight down while the anodizing resists corrosion in under-hood fuel and oil service.
It connects -4AN female to -4AN male components such as oil pumps, fuel pumps, fuel filters, regulators, and braided hose ends. It suits both naturally aspirated and forced induction applications running -4AN line.
AN fittings use a standardized 37-degree flare, so this -4AN adapter mates with standard -4AN hose ends and components regardless of brand. Confirm the connecting parts are true -4AN before assembly.
-4AN corresponds to a 1/4-inch nominal line size. Both ends of this adapter are -4AN, so it bridges two quarter-inch AN connections while adding the 45-degree offset.
