8AN to 1/4NPSM AN/JIC Flare

The 8AN to 1/4NPSM AN/JIC Flare fitting from REDHORSE PERFORMANCE is a vital hydraulic and fuel system adapter designed for engine builders and automotive technicians. This adapter connects two industry-standard thread sizes—8 AN to 1/4 NPSM—facilitating integration between aftermarket plumbing systems and factory or custom manifold ports. It is particularly useful for fabricating custom fuel rails, turbo oil cooler lines, or hydraulic brake systems during engine swaps.

REDHORSE PERFORMANCE AN/JIC flare fittings feature precision-engineered dual-cone flare geometry that ensures leak-free connections under high pressure and thermal cycling. The 8AN side accommodates standard hose barbs, crimped fittings, or braided PTFE lines, while the 1/4NPSM port threads directly into aluminum or cast-iron blocks without the need for adapter spool pieces. Constructed from aerospace-grade aluminum alloy, these fittings are designed to withstand fuel system pressures exceeding 100 psi and oil temperatures above 250°F, making them ideal for turbo and supercharger applications.

This adapter is essential for LS swaps, rotary conversions, and late-model fuel injection retrofits where 8AN braided hose systems are required. Its compact profile of 2.8 x 1 x 3.8 inches minimizes underhood packaging constraints, making it suitable for tight engine compartments. Whether you're a professional or a DIY enthusiast, this fitting provides a reliable solution for your high-performance automotive needs.
