🚗 6AN to 3/8 NPT adapter fitting – Universal Application

Compatible with 6AN hoses and 3/8″ NPT ports, making it ideal for:

• Fuel system components (rails, regulators)

• Oil pressure sensors and oil cooler setups

• Turbo oil feed/return configurations

• Aftermarket fuel pressure regulators

• Custom performance plumbing

Basically, anywhere AN meets pipe thread—and refuses to cooperate.

Material: Made of aluminum alloy 6061-T6, anodized black surface.

⚙️ Ideal Use Cases

• Converting fuel system components to AN lines

• Connecting sensors and gauges to AN setups

• Custom turbo oil feed systems

• Engine bay plumbing upgrades

Why this matters:
👉 Ensures proper compatibility between systems
👉 Prevents leaks at thread connections
👉 Simplifies complex builds

Because mismatched fittings are how leaks—and headaches—happen.

Sealing: The AN side of the flare is sealed by a 37 degree angle and the NPT thread side is sealed by a 60 degree tapered thread.

⚠️ Reality Check

• Use thread sealant on the NPT side (it’s tapered, it needs it)

• Do NOT use sealant on the AN flare side

• Avoid overtightening—aluminum threads don’t forgive mistakes

Yes, this is one of those installs where details matter.

🔥 Why Choose EVIL ENERGY 6AN to 3/8 NPT adapter fitting?

• Affordable AN-to-NPT conversion solution

• Clean black anodized finish

• Precision-machined for reliable sealing

• 2PCS set adds flexibility and value

This is the part that makes incompatible systems suddenly work together.

Application: Widely used in fuel systems, cooling systems, power steering systems, etc.
Notice: To ensure no leakage at the NPT end, sealant or PTFE tape is strongly recommended.

🏁 Final Verdict

The EVIL ENERGY 6AN Male Flare to 3/8″ NPT Straight Adapter is a must-have for any build mixing AN plumbing with pipe-thread components.

Simple, essential, and problem-solving—because your build should go together, not fight you.
