AN to ORB Fittings

Modern high-performance fuel pressure regulators typically feature a flat, straight-thread port rather than a tapered one. High-end automotive components utilize O-ring boss fittings because they seal via an O-ring fitting rather than thread interference. Evil Energy Orb Fittings allow for repeated assembly and disassembly without damaging the threads—a critical feature for track-side tuning. Unlike NPT, which can create aluminum shavings and lead to leaks after multiple uses, an AN Orb provides a clean, reliable mechanical seal every time.

Using standard rubber seals with E85 or methanol will cause the O-ring to swell or crack, leading to dangerous fuel sprays. Total compatibility is our standard. Every Orb AN fitting within the Evil Energy AN fittings line comes equipped with high-grade Viton (FKM) O-rings. Viton is chemically resistant to E85, ethanol, methanol, and synthetic oils. By choosing Evil Energy Fittings, you ensure your AN Orb fitting remains pliable and leak-free even in the most aggressive fuel environments.

Beginners often apply thread sealant to every fitting, which is a critical error for Orb fittings. Never use Teflon tape. The sealing logic of an O-ring fitting relies entirely on the compression of the O-ring within the designated groove. Applying tape to AN Orb threads can prevent the fitting from seating properly and may even introduce debris into your fuel injectors. When installing Evil Energy Orb Fittings, simply apply a drop of assembly lube to the O-ring and thread it in for a professional-grade seal.

Users often confuse the two ends of an adapter, leading to the wrong AN Orb fitting being ordered. They are not the same. A standard Orb AN fitting typically features a 37-degree Flare on one end (to connect the hose) and an AN Orb straight thread on the other (to connect to the device). While both may be labeled 'AN6,' the thread pitch and sealing method differ completely. Evil Energy fittings provide detailed sizing charts for all Orb fittings to ensure you match the straight-thread port of your fuel rail or pump correctly.

Low-quality adapters without a proper groove often result in the O-ring being pinched or sheared off during tightening. This is a hallmark of Evil Energy AN fittings engineering. Each AN Orb adapter is CNC-machined with a precision O-ring groove (undercut). This pocket retains the O-ring fitting during installation, ensuring that when you reach the recommended torque, the seal is compressed perfectly without being extruded. This industrial precision makes Evil Energy Orb Fittings the top choice for professional mechanics.
