16AN FM to 16AN FM Swivel Coupler 90Deg BLK

The 16AN FM to 16AN FM Swivel Coupler 90Deg BLK from REDHORSE PERFORMANCE is an essential adapter fitting for custom fuel, coolant, and hydraulic line routing in performance automotive builds. This 90-degree swivel coupler allows mechanics and enthusiasts to change line direction mid-run without requiring multiple fittings or complex plumbing layouts. Whether you're fabricating a custom fuel system for a turbocharged engine, rerouting brake lines around engine bay obstacles, or designing a custom cooling circuit, this adapter provides the flexibility to achieve professional results in tight spaces where straight runs aren't possible.

Constructed from aluminum and finished in black anodized coating, this 16AN swivel coupler delivers both durability and corrosion resistance in demanding underhood environments. The 90-degree design enables direct path changes while the dual 16AN female swivel connections accept standard 16AN hose ends, fittings, or adapters on both ports. Swivel technology is critical here—it compensates for minor assembly misalignments during installation and reduces vibration-induced stress on hose barbs and adapters, extending system lifespan. The compact 3.8 x 1.55 x 5.25-inch footprint and lightweight 0.3-pound design make it ideal for space-constrained engine bays where real estate is at a premium.

This fitting is built for fabricators tackling custom fuel systems, intercooler plumbing, turbo coolant lines, and brake system modifications across street rods, race cars, and heavily modified trucks. Professional installers and DIY builders alike rely on REDHORSE swivel adapters to simplify complex hose routing while maintaining full flow and pressure integrity. Before installation, verify your hose end type matches 16AN specifications and ensure all connections are properly sealed with appropriate thread sealant or O-ring lubrication. The black anodized finish complements modern engine bays while protecting aluminum surfaces from oxidation and galvanic corrosion over years of service.
