EVIL ENERGY 8AN Y-Block Flare Adapter Black — 6061-T6 Anodized, 4000 PSI

EVIL ENERGY 8AN Y Block Flare Fitting Adapter Union Splitter in black is a high-flow 60° Y-split AN union designed to divide one 8AN line into two while maintaining a 37° flare seal and rated for demanding pressure and temperature ranges.

This compact aluminum Y-block brings professional-grade hardware to fuel, oil, coolant, brake bleed, and other fluid or gas plumbing systems where space, flow balance, and leak-proof connections matter. Machined from 6061-T6 aluminum and finished with a hard-anodized black surface, the adapter combines corrosion resistance with precise thread and sealing geometry for reliable installation in workshops, race cars, boats, and industrial rigs.

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

The adapter uses the AN flare standard—an internal 37° sealing angle—to create a metal-to-metal seal when paired with proper male fittings. Threads are 8AN (3/4-16 UNF), ensuring compatibility with standard AN hoses and fittings. Proper torque and compatible flare fittings give a robust seal that resists vibration and pressure cycling.

• 37° flare sealing angle for metal-to-metal contact
• 3/4-16 UNF thread size matching 8AN standards
• Hard-anodized finish reduces galling on threads during assembly
• Best used with matching AN male fittings and hoses

What pressure and temperature limits should I expect?

This splitter is engineered to operate within a wide range of harsh environments. The published maximum working pressure is 4,000 PSI, and the usable temperature span covers extreme cold to high-heat situations. Always confirm pressure and temperature compatibility with your system and use proper clamps and hoses rated for similar conditions.

• Maximum working pressure: 4,000 PSI
• Operating temperature range: -65°F to 252°F
• Suitable for most automotive, marine, and industrial fluids within these limits
• Not a substitute for pressure-relief or safety devices

Why choose aluminum 6061-T6 with an anodized surface?

6061-T6 aluminum balances strength, weight, and machinability, making it a common choice for performance plumbing parts. The black anodized layer adds surface hardness and corrosion resistance while giving a professional, low-reflective finish. That combination keeps fitting weight down without compromising durability in demanding uses.

• 6061-T6 offers high tensile strength with lightweight construction
• Anodized black surface resists corrosion and wear
• Precision machining maintains thread accuracy and flare geometry
• Smoother exterior lowers risk of scratching hoses and adjacent parts

How does the 60° split angle affect installation and flow?

The Y-block splits flow at a 60° angle to provide an efficient path for fluid or gas while minimizing sharp turns that impede flow. The geometry helps maintain higher throughput compared with tighter-angle splitters and can simplify routing in tight compartments. Use hose lengths and clamps that match the flow needs of each branch to avoid pressure drop or imbalance.

• 60° split reduces turbulence and pressure losses versus sharper angles
• Simplifies hose routing in confined engine bays or equipment spaces
• Recommended for applications requiring balanced high flow to two outlets
• Pair with properly sized hoses and fittings for best performance

Who is this for: The EVIL ENERGY 8AN Y Block Flare Fitting Adapter is aimed at mechanics, fabricators, race teams, boat owners, and industrial technicians who need a compact, reliable way to split an 8AN line into two outlets. It suits anyone building or repairing fluid systems where high working pressure, temperature tolerance, and secure AN flare seals are required. If you need a lightweight, corrosion-resistant, precision-machined splitter that matches 8AN hardware and streamlines plumbing in tight spaces, this adapter is a practical choice.
