EVIL ENERGY 6AN to 3/8" NPT 90° Adapter Elbow — 2-Pack, 6061-T6 Aluminum Black Anodized

EVIL ENERGY 6AN male flare to 3/8" NPT 90° adapter (2 pieces) is a machined aluminum elbow that converts a 6AN flare connection to a tapered 3/8" NPT pipe thread at a right angle.

This pair of 90-degree fittings lets you change line routing where a compact, durable conversion is needed between AN-style flare fittings and NPT pipe threads. Each adapter is CNC-machined from aircraft-grade 6061-T6 aluminum and finished with black anodizing for corrosion resistance and a low-profile look. The elbow design reduces clearances and keeps hoses neatly oriented while providing two different sealing geometries: a 37° flare seat on the AN side and a 60° taper on the NPT side.

How does this adapter create a secure connection between AN and NPT fittings?

The adapter uses two different sealing methods to join dissimilar thread systems: the AN side seals with a 37° flare angle while the NPT side seals via a tapered 60° thread. Because NPT relies on thread taper for a pressure-tight seal, a sealant such as PTFE tape or pipe compound is advised to prevent leaks. The precision-machined flare face ensures a metal-to-metal seat on the AN side when tightened to spec.

• 37° flare seat on the 6AN male end for metal-to-metal sealing
• 3/8" NPT tapered threads (60°) on the pipe side for pressure sealing
• Use PTFE tape or thread sealant on NPT for leak prevention
• Hand- or wrench-tighten per torque guidelines to avoid damage

What materials and finishes are used, and why do they matter?

These elbows are crafted from 6061-T6 aluminum, a standard material for automotive and performance fluid fittings because it balances strength and weight. A hard black anodized coating improves wear and corrosion resistance while giving the fittings a professional appearance. The combination keeps overall assembly weight low and resists common automotive environments like fuel, coolant, and power steering fluids.

• 6061-T6 aluminum body for strength and low weight
• Black anodized finish for corrosion resistance and durability
• CNC machining for consistent thread and flare tolerances
• Smooth internal surfaces to reduce flow disruption

When should I choose the 90-degree 6AN to 3/8" NPT elbow for my project?

Choose this adapter when you need to reroute lines close to engine bays, tight assemblies, or where hoses must clear obstacles without kinking. The 90° bend minimizes the need for additional hoses or fittings, which can simplify installation and reduce leak points. It's suitable wherever one side of your system uses AN fittings and the other uses NPT pipe threads.

• Compact routing in tight engine or chassis spaces
• Conversions between AN hoses and NPT-threaded components
• Applications such as fuel, cooling, or power steering lines
• When a durable, low-weight elbow is preferred

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

Proper installation starts with clean threads and the correct sealant on the NPT side — PTFE tape or thread compound is recommended. Tighten the AN flare side until the 37° seat contacts the mating flare; use a wrench for final seating while avoiding over-torque. Periodic inspection for signs of seepage or corrosion will keep the system reliable.

• Clean mating surfaces before assembly
• Apply PTFE tape or pipe sealant to NPT threads
• Tighten flare until seated; use wrench for final torque
• Inspect regularly for leaks and replace if damaged

Who is this for: This two-pack of EVIL ENERGY 6AN-to-3/8" NPT 90° adapters is aimed at mechanics, fabricators, and performance enthusiasts who need a compact, reliable conversion between AN and NPT systems. It works well for custom fuel, cooling, or power steering setups, restorations where mixed-thread fittings exist, and any build that benefits from a lightweight, anodized elbow for clean hose routing. Note: always use appropriate sealants on NPT threads and follow torque specifications for your system.
