EVIL ENERGY 6AN Male to Dual 6AN Y-Block Adapter, Black Aluminum, 1500 PSI, 37-degree AN

This compact Y-block fitting is designed for vehicles, racing builds, industrial systems and custom plumbing where a single 6AN feed must be split into two equal 6AN outputs. Machined from 6061-T6 aluminum and finished with a black anodized coating, the adapter balances strength, corrosion resistance and lightweight performance. The connection uses standard 6AN threads (9/16-18 UNF) and 37-degree sealing faces common to AN fittings, providing a sealed union when paired with appropriate hoses or couplers.

How does the 6AN Y block handle pressure and temperature?

The adapter is rated for a maximum working pressure of 1500 PSI and a wide operating temperature window from -40°F to 250°F, making it suitable for many automotive and industrial fluid systems. Performance depends on proper installation, compatible hoses and fittings, and the characteristics of the fluid being transported.

• Max working pressure: 1500 PSI
• Temperature range: -40°F to 250°F
• Use with compatible AN-rated hoses and fittings for rated performance

What materials and finishes are used, and why do they matter?

The body is machined from 6061-T6 aluminum, chosen for its strength-to-weight ratio and machinability. A black anodized surface improves resistance to corrosion, oil exposure and wear while maintaining a lightweight profile compared with steel alternatives.

• 6061-T6 aluminum construction for durability and lightness
• Black anodized finish resists rust, oil and corrosion
• Metal construction prevents deformation under normal operating loads

Which fluids and systems can use this AN Y fitting?

The EVIL ENERGY Y block is compatible with a broad range of fluids and gases commonly handled by AN systems, including oil, fuel, coolant, water, air and gas. It splits flow in parallel, suitable for feeding two components from one supply line or creating redundant feed paths where needed.

• Compatible with oil, fuel, coolant, water, air and many gases
• Designed for parallel flow splitting—one inlet to two outlets
• Not for use with incompatible fluids or where chemical compatibility is unknown

How do I connect and seal this 6AN splitter correctly?

The AN side uses a 37-degree sealing angle standard to AN fittings; proper mating with AN hoses, adapters or unions ensures a fluid-tight connection. Use the correct torque, inspection, and compatible sealing surfaces to avoid leaks and maintain the rated pressure capability.

• Thread size: 6AN (9/16-18 UNF)
• Sealing method: 37-degree AN flare seats
• Install with matching AN fittings and recommended torque practices

Who is this for: This EVIL ENERGY 6AN Y-block fitting suits mechanics, tuners, fabricators and engineers building or repairing performance fuel, oil and cooling systems, as well as hobbyists performing custom plumbing or manifold work. If you need a compact, anodized aluminum splitter that matches standard AN fittings and handles moderate pressures and temperatures, this adapter is built for those applications.
