EVIL ENERGY 4AN Straight Swivel Hose End Fittings — Black Pair, 360° Rotating Collar, 1500 PSI

EVIL ENERGY 4AN straight swivel hose-end fittings are durable 6061‑T6 aluminum connectors designed to join 4AN (7/16‑20 UNF) lines to stainless steel or nylon braided CPE hoses with a 360° rotating collar for easy assembly.

These two black fittings come as a pair and are engineered for high-pressure fluid lines where a secure, reusable seal and flexible routing matter. Built to withstand tough automotive and industrial environments, the fittings use a 37° AN sealing seat and are specially shaped to mate with braided hoses rather than push-on or barbed connections. The corrosion-resistant aluminum body keeps weight low while providing reliable performance across a wide temperature range.

How do these fittings attach to my braided CPE hose?

The fitting secures to stainless steel or nylon braided CPE hose by compressing the hose end against the 37° AN sealing seat, while the threaded 7/16‑20 UNF (4AN) portion connects to mating AN ports or adapters. The swivel collar spins independently so you can tighten the thread without twisting the hose.

• Thread size: 4AN (7/16‑20 UNF) compatible with standard AN ports.
• Sealing: 37° AN cone seat for a metal‑to‑metal seal.
• Swivel: 360° rotating collar to prevent hose torsion during install.

What performance and temperature limits should I expect?

These fittings are rated for a maximum working pressure of 1,500 PSI, making them suitable for many fluid-transfer and fuel-line uses that require robust pressure handling. They also operate reliably across a broad temperature span, so they perform in both cold starts and hot running conditions.

• Maximum working pressure: 1,500 PSI.
• Operating temperature range: -40°F to 248°F (-40°C to 120°C).
• Reusability: Designed to be removed and reinstalled multiple times.

What materials and build details affect durability?

The fittings are machined from 6061‑T6 aluminum, offering an excellent strength‑to‑weight ratio and good resistance to corrosion when used in typical environments. The black finish gives extra protection and a clean appearance for visible hose runs.

• Body material: 6061‑T6 aluminum alloy for light weight and strength.
• Finish: black-coated surface to resist wear and improve aesthetics.
• Design: precision 37° seat and threaded AN connection for leak‑resistant joints.

Can these fittings be used for fuel, oil, or coolant lines?

They are intended for use on braided stainless or nylon CPE hoses and are commonly used in fuel, oil, and many fluid-transfer applications where AN fittings are suitable. Avoid use with incompatible hose types or fluids that require special seals; always confirm chemical compatibility with your hose and system requirements.

• Compatible hoses: stainless steel braided and nylon braided CPE hoses only.
• Not suitable: push‑fit, barbed, or non‑braided hose ends without proper adapters.
• Reusable: fittings can be dismantled and reattached when servicing lines.

Who is this for? The EVIL ENERGY 4AN straight swivel hose end fittings are ideal for DIY mechanics, race teams, and maintenance technicians who need compact, lightweight AN connections for braided CPE hoses. Choose these if you want a reusable, rotatable 4AN connector with a metal AN seat, rated for up to 1,500 PSI and usable across a wide temperature window. If your project requires a different thread size, non‑AN sealing style, or a barb connection for non‑braided hose, look for a fitting engineered for those specific needs.
