EVIL ENERGY AN6 90° Female-to-Female Swivel Coupler Adapter, Black Aluminum 2-Pack — Reusable 360° Swivel

EVIL ENERGY 6AN female-to-female 90° swivel coupler — a compact, reusable aluminum union that joins two AN6 lines at a sealed 90-degree angle with full 360° swivel action.

Designed for fuel, oil, coolant and braided-line systems that use AN6 fittings, this two-piece adapter provides a space-saving elbow connection without requiring hose twisting. Machined from 6061-T6 aluminum and finished in black anodize, the pair offers corrosion resistance and light weight while meeting the thread and flare standards expected in performance plumbing. Its construction balances secure sealing, serviceability and a working range suitable for many automotive and industrial fluid applications.

How does the 90° swivel help during installation?

The swivel union rotates freely at the joint so you can orient hoses after they are tightened, reducing stress and eliminating awkward bends. That makes routing simpler in cramped engine bays and speeds up assembly or maintenance.

• 360° swivel allows post-tightening alignment.
• Reduces hose twisting and potential chafing.
• Saves time when positioning fittings in tight spaces.

What sealing and thread standards does this adapter use?

This coupler uses AN6 flare sealing with a 37° contact angle and a 9/16-18 UNF thread form for the threaded portion. The mating surfaces form a metal-to-metal flare seal common to AN line fittings, giving predictable sealing behavior with compatible AN hoses and adapters.

• AN6 flare connection sealed at 37° angle.
• Thread size: 9/16-18 UNF for standard compatibility.
• Metal-to-metal seal suitable with correct AN hose assemblies.

What are the operating limits and material benefits?

Machined from 6061-T6 aluminum with a black anodized finish, the coupler offers a lightweight, corrosion-resistant option for many fluid systems. It is rated to a maximum working pressure of 1,500 PSI and designed to tolerate temperatures from -40°F up to 250°F, covering a broad range of typical automotive and light industrial uses.

• Material: 6061-T6 aluminum for strength and low weight.
• Finish: black anodize for corrosion resistance and appearance.
• Working pressure: up to 1,500 PSI; temperature range: -40°F to 250°F.

Can this adapter be reused and is it serviceable?

Yes — the union is designed for disassembly and reassembly, allowing reuse during maintenance or rerouting. The simple swivel design and standard thread/flair interfaces make it straightforward to inspect seals and replace if needed.

• Reusable construction for multiple service cycles.
• Easy disassembly for inspection or hose replacement.
• Compact form factor simplifies swaps in existing systems.

Who is this for: This EVIL ENERGY 6AN female-to-female 90° swivel coupler is intended for mechanics, fabricators, racers and DIY vehicle enthusiasts who need a compact, serviceable elbow for AN6 fluid lines. It suits applications where saving space, reducing hose stress and maintaining standard AN sealing practice matter — including fuel, oil, coolant or other non-corrosive fluid systems that match AN6 specifications.
