The #6 Female AN to 1/4 inch NPT adapter by EARLS is an essential hydraulic and pneumatic fitting for serious automotive enthusiasts and mechanics working on fuel systems, brake lines, and performance cooling applications. This adapter bridges two industry-standard connection types, allowing seamless integration between AN-specification hard lines and NPT-threaded ports found on engines, transmissions, and aftermarket components. Whether you're building a custom fuel system, upgrading to braided stainless steel lines, or fabricating a high-flow cooling circuit, this compact adapter eliminates the need for costly custom fabrication and ensures reliable, leak-free connections.
The #6 Female AN to 1/4 inch NPT adapter features precision engineering typical of EARLS' reputation for quality hydraulic fittings. The female AN thread (SAE J518 standard) mates securely with #6 AN hard lines or hose ends, while the 1/4 inch NPT (National Pipe Thread) side connects directly to engine block ports, radiator housings, transmission coolers, and carbureted fuel systems. EARLS' manufacturing ensures tight tolerances and proper sealing without leakage under pressure, critical when managing fuel delivery, coolant circulation, or brake fluid flow at operating temperatures and dynamic conditions. The lightweight construction at just 0.02 lbs makes it ideal for weight-conscious racing builds without sacrificing durability.
This adapter serves track mechanics, street rod builders, and engine bay restorers who demand OEM-quality connections in non-OEM configurations. It's particularly valuable when converting carbureted engines to fuel injection, installing remote oil coolers, upgrading intercooler plumbing on turbocharged platforms, or retrofitting modern cooling solutions into classic vehicles. Installation requires no special tools beyond standard wrenches—simply thread the NPT end into the engine port using appropriate thread sealant and torque the AN female end onto your hard line fitting. Compatibility spans domestic and imported vehicles across all engine types, making the #6 Female AN to 1/4 inch NPT adapter an indispensable shop staple for custom builds and performance modifications.
