EVIL ENERGY 8AN Flare to AN10 ORB O-Ring Adapter Set (2pcs) — 6061-T6 Aluminum, 1500 PSI

EVIL ENERGY's 8AN flare to AN10 ORB male O-ring adapter is a compact, high-pressure aluminum fitting that converts a 3/4-16 UNF 8AN flare connection to a 7/8-14 UNF AN10 ORB O-ring seal — sold as a set of two.

This adapter bridges two common fuel- and oil-system standards so you can join an 8AN flare line to an AN10 ORB port without modifying existing hoses or fittings. Machined from 6061-T6 aluminum and finished for corrosion resistance, each adapter uses a 37° flare seal on the AN side and an NBR O-ring on the ORB side to create a secure, reusable joint rated for demanding automotive and performance applications.

How does this adapter make plumbing fuel and oil systems easier?

The adapter saves time and avoids custom fabrication by converting thread types and sealing methods in a single part. Instead of replacing hoses or ports, you attach the flare hose to the 8AN side and press the O-ring end into the AN10 ORB port for an immediate seal. Installation is straightforward and reversible, which helps when swapping components during tuning or maintenance.

• Directly converts 8AN (3/4-16 UNF) flare to AN10 ORB (7/8-14 UNF) O-ring port
• No thread chasing or hose cutting required
• Sold as a convenient two-piece set for paired fittings or redundancy

What are the material and temperature limits I should expect?

Each adapter uses a 6061-T6 aluminum body for strength and light weight, combined with an NBR rubber O-ring for reliable sealing. The assembly is rated for working pressures up to 1500 PSI and withstands wide temperature ranges suitable for most automotive fluids.

• Body: aluminum alloy 6061-T6 for corrosion resistance and durability
• O-ring: NBR rubber with a service range listed to -4°F to 392°F
• Working pressure: rated up to 1500 PSI; adapter temperature range -65°F to 252°F

Which applications are these adapters designed for?

The adapter is intended for fuel-system and oil-system connections where AN flare fittings must mate to AN10 ORB ports. Typical uses include fuel rails, oil coolers, pumps, pressure regulators and filters on performance vehicles, racecars, and upgraded street machines.

• Compatible with fuel rails, fuel pumps, and filters
• Works with oil coolers and remote mount pressure regulators
• Useful in retrofit or upgrade projects that mix flare and ORB ports

How do I install and maintain the adapter for best reliability?

Installation requires clean mating surfaces and a properly sized O-ring; lubricating the O-ring lightly with compatible fluid can ease seating. Tighten the flare connection to the manufacturer's torque spec and press the ORB end into the port until the O-ring seats; inspect periodically for leaks and replace O-rings if they show wear.

• Clean threads and ports before assembly to prevent contamination
• Use correct torque on the 8AN flare nut — avoid over-tightening
• Replace O-rings during service intervals or if cracked/flattened

Who is this for: EVIL ENERGY's 8AN Flare to AN10 ORB male O-ring adapter set is aimed at mechanics, fabricators, and performance vehicle owners who need a compact, reliable way to join 8AN flare hoses to AN10 ORB ports. It's ideal for shop technicians and enthusiasts performing upgrades, repairs, or custom plumbing on fuel and oil systems where space, pressure rating, and serviceability matter.
