EVIL ENERGY 8AN Y Block Flare Fitting Adapter Union

EVIL ENERGY's 8AN Y Block Flare Fitting is a compact, anodized-aluminum union splitter that divides a single 8AN line into two 8AN outlets while maintaining a 37° flare seal.

This precision-machined Y-block adapter makes it simple to split fluid or gas flow in automotive, motorsport, marine, or industrial plumbing systems where AN fittings are used. Built from 6061-T6 aluminum with a black anodized finish, the adapter combines corrosion resistance with a light, durable profile. It’s engineered for high-pressure service and wide temperature ranges, so it integrates cleanly into fuel, oil, coolant, or other pressurized lines that require reliable 37° flare sealing.

How does the 8AN Y Block keep a leak-free connection?

The adapter relies on standard 37° AN flare sealing geometry to form metal-to-metal contact at each port, matching common AN flare fittings. Properly flared hoses and tightened fittings create a robust mechanical seal without additional gaskets. The anodized surface also helps resist corrosion where fittings join.

• 37° flare sealing on each AN port for metal-to-metal contact
• 3/4-16 UNF thread specification for 8AN compatibility
• Black anodized finish reduces surface oxidation at connection points

What pressures and temperatures can this splitter handle?

This Y-block is rated for high-pressure systems and a broad temperature span, suitable where elevated pressures and extreme temperatures occur. Always confirm system components and hose ratings are compatible with the adapter’s limits before installation. For critical systems, follow manufacturer torque and installation guidance.

• Maximum working pressure: 4000 PSI
• Operating temperature range: -65°F to 252°F
• Designed for liquid and gas applications within these parameters

Which materials and machining features ensure durability?

The Y-block is crafted from aerospace-grade 6061-T6 aluminum that balances strength and weight. CNC machining yields precise threads and flare seats, while the anodized black surface improves wear and corrosion resistance. Those construction choices deliver long service life in demanding environments.

• Material: 6061-T6 aluminum for strength and lightness
• Black anodized finish for corrosion and wear resistance
• Precision-machined flare seats and threads for proper fit

How does the adapter split flow and where is it best used?

The body divides a single 8AN inlet into two 8AN outlets at a 60° split angle, allowing parallel feeds from one source. That geometry favors even flow distribution and convenient routing in tight assemblies. Use it where duplicate feeds are needed — for example, feeding two components from one supply line without using extra fittings or hoses.

• Split flow angle: 60° for compact routing and parallel feeds
• Works with fluids and gases compatible with aluminum and AN flares
• Ideal for fuel, oil, coolant, or other pressurized AN systems

Who is this for: The EVIL ENERGY 8AN Y Block Flare Fitting suits mechanics, race teams, fabricators, and DIY enthusiasts needing a compact, high-pressure AN line splitter. It’s a practical choice when adding a second feed without major rework, or when replacing bulky or corroded fittings with a lightweight, anodized aluminum component. Ensure your hoses, clamps, and system ratings match the adapter’s 8AN size, pressure, and temperature limits before installation.
