About this item

Product details

Upgrade your custom fuel system with the EVIL ENERGY AN Flare to AN ORB Male Adapter Fitting — a precision CNC-machined 6061-T6 aluminum connector that converts AN 37-degree flare fittings to AN ORB (O-ring boss) ports for fuel rails, fuel pressure regulators, fuel filters, fuel pumps and oil coolers. Rated for up to 1500 PSI and operating from -65°F to 252°F, it handles high-pressure fuel, oil and coolant lines with confidence. The AN side uses a 37-degree flare for a secure metal-to-metal seal, while the ORB side pairs with a replaceable NBR O-ring to deliver a leak-resistant, vibration-proof connection. The black anodized finish resists corrosion, fuel and oil exposure, and the lightweight 6061-T6 body provides long-lasting durability without adding weight.
