10AN Flare Plug 1/pkg Black

The 10AN Flare Plug 1/pkg Black from REDHORSE PERFORMANCE is an essential fluid system component for any serious performance engine builder or custom fuel system installer. Whether you're fabricating a high-pressure fuel line setup, building a turbo intercooler circuit, or assembling a custom hydraulic cooling system, this flare plug blocks off unused 10AN ports with professional precision. It's the kind of detail that separates a proper build from one prone to leaks and pressure loss, making it indispensable for street machines, race engines, and heavily modified vehicles where every connection matters.

Built to REDHORSE PERFORMANCE's exacting standards, this 10AN flare plug features a JIC-standard 37-degree flare seat that mates perfectly with AN hose fittings and manifold ports designed for 10AN connectivity. The black anodized aluminum construction resists corrosion while maintaining a clean, OEM-quality appearance in engine bays. The flare design ensures a bubble-tight seal without requiring thread sealant, preventing contamination of fuel systems or coolant circuits—critical for fuel injector cleanliness and cooling system integrity. The compact form factor (2.8 x 1.15 x 3.85 inches) allows installation in tight spaces common to performance engine compartments where real estate is at a premium.

This plug excels for motorsport enthusiasts, professional tuners, and fabricators working on fuel system upgrades, turbo plumbing, or auxiliary cooling systems where unused 10AN ports must be sealed cleanly and reliably. One plug per package makes it ideal for single-port applications or as a spare for emergency field repairs. Compatible with any manifold, fuel rail, or custom bracket featuring standard 10AN JIC ports, the REDHORSE 10AN Flare Plug delivers the dependable performance and leak-free operation expected in competition and street-driven builds.
