EVIL ENERGY 6AN to 1/4" NPT 90° Aluminum Adapter Black 2-Pack — 6061-T6 Anodized, Compact

EVIL ENERGY 6AN to 1/4" NPT 90° fitting adapters are compact, anodized 90-degree elbows that convert a 6AN flare connection to a 1/4" NPT male thread for fuel, coolant, and steering lines. These two-pack, 90-degree aluminum adapters let you join AN-style flare lines to tapered NPT ports where space is tight or routing requires a right-angle turn. Machined from 6061-T6 aluminum and finished with a black anodized surface, each fitting combines a 37° AN flare sealing face with a 60° tapered NPT thread. The pairing is a practical solution for custom plumbing on vehicles, racecars, boats, and industrial equipment — especially when converting between metric and standard fittings or adapting aftermarket components.

How do these adapters seal reliably between AN and NPT systems?

The AN side uses a 37° flare that seals by metal-to-metal contact when mated to a corresponding female AN fitting. The NPT side relies on the tapered 60° thread to form a pressure-tight seal when combined with a compatible sealant or PTFE tape.

• AN connection: 37° flare face for direct metal sealing.
• NPT connection: 1/4" tapered thread (60°) requiring thread sealant.
• Recommendation: apply PTFE tape or thread sealant to NPT threads before assembly.

Will these adapters withstand automotive conditions and frequent removal?

Constructed from 6061-T6 aluminum and anodized for surface durability, the adapters resist corrosion and hold up under typical automotive temperatures and vibration. The aluminum body is light yet strong, and anodizing reduces wear from repeated wrenching.

• Material: CNC-machined 6061-T6 aluminum for strength-to-weight balance.
• Finish: black anodized surface improves corrosion resistance.
• Serviceability: robust hex flats permit easy installation and removal with a wrench.

What applications are these 90° fittings best suited for?

These elbows are commonly used where an AN hose or line must connect to a female NPT port at a right angle. Typical uses include fuel rails, cooling lines, power steering plumbing, and aftermarket sensors or fittings that use NPT threads.

• Fuel system routing where AN hoses meet NPT ports on pumps or carburetors.
• Cooling and heater hose adapters in confined engine bays.
• Power steering and hydraulic line changes requiring a 90° turn.

How should I install and maintain these adapters to avoid leaks?

Clean mating surfaces, hand-start threads to avoid cross-threading, and use an appropriate sealant on the NPT side to ensure a leak-free joint. Tighten to a firm wrench torque — avoid over-torquing aluminum threads — and inspect periodically for loosening or sealant degradation.

• Prep: clean threads and AN flare faces before assembly.
• Seal: use PTFE tape or pipe thread sealant on the NPT side only.
• Torque: tighten with a wrench on the hex flats; avoid excessive force to protect threads.

Who is this for These EVIL ENERGY 6AN to 1/4" NPT 90° adapters are aimed at DIY mechanics, tuners, fabricators, and professionals who need a reliable right-angle transition between AN flare lines and NPT ports. They suit applications where space constraints or routing require a compact elbow, where corrosion-resistant lightweight components are preferred, and where periodic servicing means fittings must be easy to install and remove. Sold as a pair, they provide a practical, reusable solution for conversions on street cars, race vehicles, marine craft, and workshop projects.

FAQ

Q: Do I need sealant on the NPT side?

A: Yes. Use PTFE tape or a pipe thread sealant on the 1/4" NPT threads to ensure a leak-free joint.

Q: Are these compatible with fuel systems?

A: Yes. Made from anodized 6061-T6 aluminum, they’re suitable for many fuel system connections when installed correctly.
