EVIL ENERGY 12AN Flare to AN12 ORB Male O-Ring 2PCS Fitting

EVIL ENERGY 12AN flare-to-AN12 ORB male O-ring adapter is a durable aluminum fitting that converts a 12AN 37° flare connection to an AN12 ORB O-ring sealed port for fuel and oil systems.

This compact adapter blends an industry-standard 12AN 37° flare thread with a female ORB-style O-ring seal to give you a reliable transition between flare hose assemblies and ORB ports. Machined from 6061-T6 aluminum and delivered with a nitrile (NBR) O-ring, the part is built for high-pressure fuel, oil cooler, regulator, and pump applications where a leak-resistant, reusable fitting is required.

How does this adapter form a leak-resistant connection?

The adapter uses two complementary sealing methods: the AN side seals on a precision 37° flare angle while the ORB side compresses an O-ring into a counterbore to create a metal-to-rubber seal. This hybrid approach reduces the chance of fluid seepage when installed correctly and torqued to spec. The O-ring is replaceable so the fitting can be serviced without replacing the entire adapter.

• AN 37° flare contact on the hose end for metal-to-metal sealing.
• ORB side uses a nitrile (NBR) O-ring for elastic, pressure-tolerant sealing.
• Thread size: 1 1/16-12 UNF (12AN / AN12) for both mating sides.
• Replaceable O-ring extends service life and eases maintenance.

Is this fitting durable enough for high-pressure fuel and oil systems?

Yes — the body is CNC-machined from 6061-T6 aluminum, offering a strong, corrosion-resistant structure suited to automotive and motorsport environments. The assembly is rated to 1500 PSI working pressure and supports a broad temperature range, making it compatible with typical fuel and lubricant operating conditions. Always verify compatibility with the fluid type and system temperature before installation.

• Material: aluminum alloy 6061-T6 for high strength and light weight.
• Working pressure rating: 1500 PSI for demanding systems.
• Working temperature: -65°F to 252°F; O-ring range: -4°F to 392°F.
• Suitable for fuel, oil, and related automotive fluids when using compatible seals.

Which applications is the EVIL ENERGY 12AN flare-to-ORB adapter best suited for?

This adapter is designed for plumbing transitions in fuel rails, oil coolers, external fuel pumps, pressure regulators, and inline fuel filters where an AN flare hose must connect to an ORB port. Its compact form factor and standard AN12 thread make it easy to swap into existing systems or incorporate into custom plumbing runs. The O-ring seal provides convenience when connecting to recessed ORB ports common on high-pressure components.

• Fuel rails and fuel system plumbing requiring AN-to-ORB transitions.
• Oil cooler lines, external fuel pumps, and fuel pressure regulators.
• Retrofit projects or custom race plumbing where leak-proof joints are critical.
• Serviceable connections thanks to replaceable NBR O-ring.

How should I install and maintain this adapter for long service life?

Install the adapter using proper thread engagement and torque values for 12AN/1 1/16-12 UNF fittings; hand-start threads to avoid cross-threading. Inspect the O-ring for nicks or hardening before assembly and replace it if signs of wear appear. Periodically check for leaks and ensure fittings remain torqued to specification, especially after heat cycles or pressure testing.

• Hand-start threads, then torque to manufacturer-recommended specs.
• Inspect and replace the NBR O-ring as part of routine maintenance.
• Check compatibility with the fluid to avoid O-ring degradation.
• Re-torque after initial pressure testing or thermal cycling.

Who is this for: This EVIL ENERGY adapter is intended for mechanics, tuners, fabricators, and DIY enthusiasts who need a dependable AN12-to-ORB transition in fuel or oil systems. It's a practical choice for automotive performance builds, track-prep vehicles, and maintenance jobs where a lightweight, serviceable fitting with high pressure capability is required. If you work with AN hose assemblies and ORB ports and require a compact, serviceable adapter rated to 1500 PSI, this piece is designed for your toolkit.
