EVIL ENERGY 10AN to 1/2" NPT Male 90 Degree Fitting Adapter

EVIL ENERGY's 10AN to 1/2" NPT 90° adapter is a black-anodized 6061-T6 aluminum elbow that converts a 10AN flare connection to a 1/2" NPT male thread in a compact right-angle form.

This two-piece adapter lets you join AN-style flare plumbing to tapered NPT fittings where a 90-degree turn is needed — commonly used in automotive fuel, cooling, or power steering lines. Machined from aircraft-grade 6061-T6 aluminum and finished with a protective black anodize, the adapters combine corrosion resistance with light weight. The AN side seals on a 37° flare face while the NPT side relies on a tapered 60° thread; proper sealant or PTFE tape is recommended to prevent leaks at the NPT thread.

How does this adapter ensure a leak-resistant connection?

The AN end uses a 37° flare seating surface for a metal-to-metal crush seal, while the NPT end forms a pressure-tight fit when combined with thread sealant. Use appropriate torque and sealing compound or PTFE tape on the NPT threads to achieve reliable sealing.

• AN side: 10AN flare (7/8-14 UNF) seats on a 37° flare face.
• NPT side: 1/2" tapered 60° thread needs sealant or PTFE tape.
• Right-angle design reduces hose bending and stress.
• Hand wrench installation; avoid over-torquing to protect threads.

What materials and finish does the adapter use for durability?

These elbows are CNC-machined from 6061-T6 aluminum, chosen for its strength-to-weight ratio and resistance to corrosion. A black anodized surface adds abrasion resistance and a finished look suitable for exposed installations.

• 6061-T6 aluminum body for lightweight strength.
• Hard-anodized black finish for surface protection and aesthetics.
• Precision machining for consistent thread fit and flare seat.
• Suitable for use in environments where corrosion resistance matters.

Where will this 90° fitting typically be used?

The elbow is commonly installed in automotive and industrial fluid systems where AN and NPT fittings must be joined at a right angle. Typical applications include fuel supply lines, coolant plumbing, power steering hoses, and custom fluid routing on performance vehicles.

• Fuel systems and feed lines where AN fittings are standard.
• Cooling system plumbing requiring an angled transition.
• Power steering hose assemblies and retrofit projects.
• Custom fabrication where space or hose clearance is limited.

How do I install and maintain these adapters for best performance?

Thread the AN flare onto the mating flare fitting and hand-tighten, then use a wrench to finish to recommended torque—avoid overtightening. Apply PTFE tape or a pipe sealant to the 1/2" NPT male threads before assembly, and periodically inspect for signs of loosening or wear.

• Seal NPT threads with PTFE tape or approved sealant before assembly.
• Use proper wrench size for installation to prevent damage.
• Check fittings regularly for leaks, especially after initial run-in.
• Replace if threads or flare seat show corrosion or deformation.

Who is this for: This 2-piece set from EVIL ENERGY is aimed at DIY mechanics, race fabricators, and professional technicians who need a robust right-angle transition between 10AN flare plumbing and 1/2" NPT systems. It’s suited for anyone building or repairing fuel, cooling, or power steering circuits where a durable, compact elbow and a clean black finish are desired. Note: because the NPT side seals on tapered threads, always use a thread sealant or PTFE tape for leak-free service.
