EVIL ENERGY AN8 Male Flare to 3/8" NPT Adapter Black 4PC — 6061‑T6 Aluminium Straight, Anodized

EVIL ENERGY AN8 male flare to 3/8" NPT straight adapter — a black anodized 6061-T6 aluminum fitting sold as a pack of four for fuel, coolant, and power-steering plumbing. These straight adapters convert AN8 (8AN) male flare connections to tapered 3/8" NPT pipe threads, offering a compact, serviceable link between hose-end hardware and NPT ports. Machined from 6061-T6 aluminum and finished with a black anodized surface, each piece uses a 37° flare seal on the AN side and a 68° taper on the NPT side; because NPT threads rely on taper sealing, thread sealant or PTFE tape is recommended to prevent leakage. The package of four is intended for performance automotive systems where light weight, corrosion resistance, and repeatable joins matter.

How do these adapters join AN and NPT systems reliably?

Each adapter combines two sealing philosophies: a machined 37° flare for the AN side and a tapered 68° NPT thread for pipe-side sealing. The flare provides a metal-to-metal crush seal when paired with a matching flare-seat, while the NPT side seals by thread interference and requires a sealing compound.

• AN side: 37° flare geometry for a predictable, reusable metal seal.
• NPT side: 68° tapered pipe thread that seals with thread sealant or PTFE tape.
• Material: 6061-T6 aluminum resists corrosion and keeps mass low.
• Finish: black anodize protects the surface and reduces galling.

What systems and fluids are these fittings suitable for?

These adapters are commonly used in fuel delivery, coolant plumbing, power steering lines, and other low- to moderate-pressure automotive applications. They are not intended for oxygen service or high-pressure hydraulic lines without verifying ratings for your specific system.

• Common uses: fuel lines, radiator/coolant plumbing, power steering hoses.
• Not recommended: oxygen or pressurized systems beyond manufacturer limits.
• Check compatibility: use appropriate seals and thread compounds for the fluid involved.

How should I install them to avoid leaks and ensure serviceability?

Hand-start the NPT threads, apply PTFE tape or pipe sealant to the male NPT portion, then tighten with a wrench until snug—do not over-torque. For the AN flare side, assemble with the correct mating nut and flare seat; tighten until the metal-to-metal contact forms a leak-free joint.

• Use PTFE tape or thread sealant on the NPT threads before assembly.
• Hand-start threads to avoid cross-threading; finish with a wrench.
• Do not over-tighten the AN flare; watch for proper flare seating.
• Inspect periodically for wear, especially in high-heat or vibration zones.

What are the physical and material details to expect?

Each adapter is machined from 6061-T6 aluminum and anodized black for durability and appearance. The part is a straight male AN8 to male 3/8" NPT adapter; sold as a set of four to outfit multiple lines or keep spares on hand.

• Size: AN8 (8AN) flare to 3/8" NPT pipe thread.
• Material: 6061-T6 aluminum with black anodized finish.
• Sealing: 37° flare on AN side; 68° tapered NPT threads.
• Quantity: 4 pieces per pack for easy replacement or multiple runs.

Who is this for: This four-pack of EVIL ENERGY AN8-to-3/8" NPT adapters is aimed at automotive technicians, fabricators, and DIY enthusiasts who need a lightweight, corrosion-resistant transition fitting between AN hose assemblies and NPT ports. Choose these when you require repeatable AN flare connections together with the ubiquity of NPT threads—just remember to use proper thread sealant on the NPT side and verify the fitting for your fluid and pressure requirements.

FAQ

Q: Do I need thread sealant on the NPT side?

A: Yes. Use PTFE tape or pipe thread sealant on the 3/8" NPT threads to ensure a reliable seal.

Q: Are these fittings suitable for fuel systems?

A: Yes. They are commonly used in fuel systems, but confirm compatibility with your fuel type and pressure.
