EVIL ENERGY 12AN to AN10 ORB Adapter, 2PCS — 6061-T6 Aluminum with NBR O-ring, 1500 PSI Leak-Resistant

EVIL ENERGY 12AN flare to AN10 ORB male O-ring adapter is a two-piece aluminum fitting that converts a 12AN flare thread to an AN10 ORB port with an O-ring seal. This compact adapter lets you join a 12AN (1 1/16-12 UNF) flare line to an AN10 ORB (7/8-14 UNF) female port without cutting or flaring tubing. Built from 6061-T6 aluminum with an NBR O-ring, it provides a corrosion-resistant connection rated for demanding automotive and motorsport fluid systems. The design pairs a 37° flare sealing geometry on the AN side with an O-ring seated on the ORB side to create a reliable, pressure-rated joint for fuel, oil, and other compatible liquids.

How does this adapter create a leak-resistant connection?

The adapter uses two complementary sealing methods: a metal-to-metal 37° flare angle on the 12AN side and a compressed NBR O-ring on the ORB side. This combination reduces the chance of leaks across threads and mating surfaces while remaining serviceable for tightening or replacement.

• 37° flare on 12AN side provides a metal seal at the flare face
• NBR O-ring on AN10 ORB side compresses into the port for a fluid-tight seal
• Thread sizes match standard AN and ORB dimensions for secure engagement

What materials and temperature/pressure limits should I expect?

The body is machined from aircraft-grade 6061-T6 aluminum, offering strength with low weight and good corrosion resistance. The included NBR rubber O-ring tolerates a broad temperature span, and the complete assembly is rated for common automotive pressures used in fuel and oil systems.

• Body: aluminum alloy 6061-T6 for durability and light weight
• O-ring: NBR rubber with an operating temperature window suitable for most engine compartments
• Working pressure: up to 1500 PSI; O-ring temperature range extends to typical service limits

Which applications are appropriate for this 12AN to AN10 ORB adapter?

This adapter is intended for fluid-transfer hardware in performance and maintenance contexts. It is commonly used where a hose with a 12AN flare fitting must interface with an AN10 ORB female port on components like pumps, rails, or filters.

• Fuel rails and high-flow fuel systems
• Oil coolers, filters, and engine oil lines
• Fuel pumps and pressure regulators that accept AN10 ORB ports

How do I install and maintain the fitting for best performance?

Installation requires matching thread engagement and correct O-ring seating; hand-start threads, then torque to manufacturer recommendations to avoid over-compression. Inspect the O-ring before reuse and replace it if cut, flattened, or hardened to retain a proper seal.

• Clean mating port and flare surfaces before assembly
• Hand-start threads to prevent cross-threading, then torque to spec
• Replace O-ring during service intervals or if damage is detected

This EVIL ENERGY adapter comes as a two-piece set (2PCS) and is engineered for installers who need a compact, dependable conversion between 12AN flare lines and AN10 ORB ports. It is not a pressure-relief device and should be used only with compatible fluids and within the stated temperature and pressure limits. If you require compatibility with incompatible fluids, consult material charts and replace the O-ring with a suitable compound. Who is this for This adapter is aimed at automotive technicians, tuners, racers, and DIY mechanics who modify fuel or oil systems and need a lightweight, high-strength connector. It suits anyone replacing components, adapting aftermarket parts, or building custom plumbing where a 12AN flare hose must mate to an AN10 ORB-style port.

FAQ

Q: Can this adapter handle fuel system pressure?

A: Yes — the adapter is rated to 1500 PSI, suitable for most fuel and oil system pressures when used with compatible hoses and fittings.

Q: Is the O-ring replaceable and what material is it?

A: Yes. The supplied O-ring is NBR rubber and can be swapped during maintenance or if degraded.
