EVIL ENERGY 8AN to 1/4-in NPT Adapter | Aluminum Straight Black 2-Pack

Overview

EVIL ENERGY delivers a reliable AN8 to 1/4-in NPT pipe fitting adapter designed for performance and durability. Cast from 6061-T6 aluminum and finished with a matte black anodized coating, this 2-pack offers a clean, space-saving solution for tight engine bays and custom routing in fuel, cooling, and steering systems.

Key specifications

• Size and fit: AN8 (3/4-16 UNF) to 1/4-in NPT with a straight configuration for straightforward installation.
• Material and finish: 6061-T6 aluminum paired with a robust black anodized surface for corrosion resistance and a refined look.
• Sealing design: 37-degree flare on the AN side creates a sealed connection, while the 60-degree tapered NPT threads rely on sealant or PTFE tape for a tight seal.
• Pack content: Includes two identical adapters, enabling paired connections or a spare for future projects.
• Versatility: Widely applicable to fuel lines, cooling circuits, power steering, and other fluid systems in performance or daily-use vehicles.

Versatile applications

• Fuel system connections where an 8AN to NPT transition is needed.
• Cooling system hose routing to adapt different thread types.
• Power steering line fittings requiring a reliable flare-to-NPT transition.
• Custom vehicle builds or repair work where a compact, strong adapter simplifies layouts.

Finish, durability, and compatibility

The aluminum alloy and black anodized finish are chosen for light weight and resistance to under-hood conditions. The straight design helps maintain clean hose routing, while the two-pack provides flexibility during upgrades or repairs. Always verify system compatibility and consider using applicable sealant or PTFE tape on the NPT end to minimize leaks across operating temperatures.

Installation tips

• Apply sealant or PTFE tape to the NPT threads before tightening with a wrench.
• Ensure proper thread engagement to avoid cross-threading and reduce service time.
• Torque to manufacturer recommendations for your specific system to maintain a reliable seal.

In practice, this adapter offers a practical way to tailor fittings without swapping hoses or bulk components. The 2-pack format supports both a primary installation and a ready spare, helping you manage routine maintenance or project work with fewer interruptions.
