#10 x 7/8-14 90 Deg Swivel Adapter Black

The #10 x 7/8-14 90 Deg Swivel Adapter Black by FRAGOLA is a precision-engineered AN fitting designed for custom fuel, oil, and coolant line routing in high-performance engine builds. Built by mechanics and fabricators who understand tight engine bays and complex plumbing layouts, this 90-degree swivel adapter solves the common problem of rigid hose runs that don't align cleanly with manifold ports or reservoir inlets. Whether you're building a turbocharged swap, installing a remote oil cooler, or running aftermarket fuel rails, this adapter lets you approach connection points at the angle that works best for your specific installation without forcing hose bends that weaken lines or create leak points.

Constructed from aluminum and finished in black anodized coating, the #10 x 7/8-14 90 Deg Swivel Adapter combines durability with corrosion resistance in engine compartment environments. The 10 AN male inlet threads to standard -10 hose fittings, while the 7/8-14 male O-ring swivel outlet accommodates factory and aftermarket fuel rails, manifolds, and distribution blocks that use SAE O-ring port specifications. The 90-degree geometry eliminates sharp bends in braided hose runs, reducing turbulence and fatigue at the connection point—critical for fuel system stability under boost or aggressive cooling demands. O-ring face seal technology ensures leak-free performance across temperature cycling and vibration, eliminating the need for PTFE tape and delivering repeatable seals across rebuild cycles.

This adapter is ideal for fabricators and DIY builders working on LS engine conversions, fuel system upgrades, and custom cooling loops where port alignment requires flexibility. The swivel design accommodates slight misalignment during installation, simplifying tight-quarters work without thread galling. Weighing just 0.14 lbs, it adds negligible mass while delivering the structural integrity needed for pressurized systems running 40+ psi fuel pressure or high-flow oil cooling circuits. Compatible with any 10 AN braided line assembly and SAE O-ring port manifolds, the #10 x 7/8-14 90 Deg Swivel Adapter Black is an essential component for professional-grade engine bay plumbing.
