EVIL ENERGY 6AN to 5/16" 90° Swivel Hose Fitting — 6061‑T6 Aluminum, Low‑Profile

EVIL ENERGY 6AN female to 5/16" barb 90° swivel hose fitting is a compact aluminum adapter that connects 6AN threaded components to 5/16" ID hose with a rotatable elbow for easier routing.

This low-profile swivel fitting converts a 6AN (9/16-18UNF) female flare connection to a 5/16" barbed hose outlet at a 90° angle, built from 6061-T6 aluminum for a high strength-to-weight ratio. It seals against the AN flare at a 37° angle and accepts push-on hose attachment to the barb; hose clamps are recommended for a secure joint. The adapter is rated for typical fuel and low-pressure fluid systems with a working pressure up to about 1500 PSI and a wide operating temperature range from -65°F to 252°F.

How does this swivel fitting simplify hose routing in tight spaces?

The 90° swivel design lets you route hose without twisting assemblies or stressing fittings, reducing installation difficulty in compact engine bays or equipment enclosures. The rotating joint realigns the barb while the female AN stays secured, so final hose positioning is easier and neater.

• 90° elbow reduces hose bend radius and interference.
• Swivel action rotates barb independently of threaded connection.
• Compact footprint for crowded plumbing layouts.

What are the key specifications and materials for durability?

Constructed from 6061-T6 aluminum, the adapter balances corrosion resistance with robust mechanical properties for automotive and industrial plumbing. The female end uses the 37° AN flare sealing geometry and the barb is sized to fit 5/16" hose ID, with ratings suited for many low- to mid-pressure fluid lines.

• Thread: 6AN (9/16-18UNF) female with 37° flare sealing.
• Barb OD: 5/16" to match common hose inner diameters.
• Material: 6061-T6 aluminum for strength and light weight.
• Working pressure ~1500 PSI; temperature -65°F to 252°F.

How should I install and secure the barb-to-hose connection?

Push the hose onto the 5/16" barb until it seats against the fitting shoulder; this friction fit creates the initial seal. For dependable long-term service, add a properly sized clamp (worm-drive, Oetiker, or similar) to compress the hose over the barb and prevent leaks or slippage under pressure or vibration.

• Push-on installation—ensure hose fully seats on the barb.
• Use hose clamp recommended for application and pressure.
• Hand-tighten the AN female to mating fitting, then torque per system specs if required.

Is this fitting compatible with fuel, coolant, or vacuum lines?

The adapter is suitable for many common fluid lines including fuel and coolant routes where the materials and pressure ratings match system requirements. Always verify chemical compatibility of the hose and clamp with the fluid in use and confirm the system’s maximum pressure and temperature fall within the fitting’s ratings.

• Commonly used with fuel, coolant, and general hydraulic or vacuum lines.
• Check hose material compatibility with your fluid (fuel, oil, coolant, etc.).
• Ensure system pressure and temperature stay within rated limits.

Who is this for: Technicians, home mechanics, and fabricators who need a rugged, low-clearance adapter to join a 6AN female flare to a 5/16" hose while preserving routing flexibility. It suits automotive performance plumbing, custom fuel or coolant lines, and industrial setups where a compact, rotatable AN-to-barb solution is required. Choose this fitting when you want a lightweight aluminum part with AN flare sealing, a 90° orientation, and an easy push-on barb for quick hose connections.
