-8AN Male to M14x1.5 Female Flare Adapter

The -8AN Male to M14x1.5 Female Flare Adapter from VIBRANT PERFORMANCE is a precision hydraulic fitting designed for serious engine builders and modification enthusiasts who demand reliable fluid transfer in custom cooling, fuel, and brake systems. This adapter bridges the gap between two industry-standard thread profiles, enabling seamless integration of AN-rated hose lines into factory or custom manifold ports that specify M14x1.5 metric threads. Whether you're upgrading a turbo cooling circuit, installing aftermarket fuel rails, or fabricating a custom brake bias setup, this adapter ensures leak-free connections under high-pressure cycling.

Manufactured by VIBRANT PERFORMANCE—a trusted name in performance plumbing for over two decades—this adapter features precision-machined aluminum construction with 37-degree flare seat geometry that mates with standard -8AN push-lock or swaged hose terminals. The M14x1.5 female port accepts metric fasteners common in European and JDM engine platforms, while the -8AN male end delivers the flow capacity and pressure rating required for forced-induction cooling loops and fuel system upgrades. The compact 3.3-inch length and minimal weight profile (0.04 lbs) make it ideal for tight engine bay installations where space and mass matter. All VIBRANT PERFORMANCE adapters are tested to meet or exceed SAE standards for burst pressure and thermal cycling durability.

This fitting is essential for engine swaps, intercooler upgrades, and custom cooling manifold fabrication on turbocharged and supercharged platforms where OEM ports don't align with modern AN hose standards. Mechanics and fabricators working on BMW, Audi, Subaru, and other metric-threaded engine bays will find this adapter invaluable for converting legacy cooling or fuel ports to modern performance plumbing. Installation requires only standard wrenches; tighten the M14x1.5 port to factory specifications (typically 25–35 Nm) and use a flare-nut wrench on the -8AN end to prevent twisting. Pair it with quality -8AN hose, fittings, and sealing washers for a professional, reliable system that handles sustained boost pressure and thermal cycling.
