EVIL ENERGY 6AN Y-Block Flare Adapter — Black Anodized 6061-T6, 4000 PSI

EVIL ENERGY's 6AN Y block flare fitting is a compact, anodized 6061-T6 aluminum 60° splitter that divides a single 6AN inlet into two 6AN outlets and is rated to 4000 PSI.

This Y block union is designed for high-flow fluid and gas systems where a reliable, leak-resistant split is required. Machined from aircraft-grade 6061-T6 aluminum and finished with a black anodized coating, the adapter uses 37° flare sealing on each AN connection to maintain a tight, repeatable seal. It fits 6AN threads (9/16-18 UNF) and operates across a wide temperature range, making it suitable for performance automotive, motorsport, industrial, and custom plumbing builds.

How does this splitter keep a secure seal under pressure?

The EVIL ENERGY Y block relies on standard AN 37° flare sealing geometry to ensure metal-to-metal contact and a consistent mating surface. Its 6061-T6 construction maintains dimensional stability under load, and the anodized finish resists corrosion that can compromise seals.

• 37° AN flare faces on each port for metal-on-metal sealing
• Precision-machined threads sized 9/16-18 UNF for tight fits
• 4000 PSI maximum working pressure rating
• Anodized surface protects against wear and corrosion

Will it survive extreme temperatures and harsh fluids?

The adapter is rated to operate between -65°F and 252°F, making it compatible with a wide range of fluids and environments. Its aluminum alloy body resists common automotive and industrial fluids, while the anodized finish adds chemical and abrasion resistance.

• Working temperature range: -65°F to 252°F
• 6061-T6 aluminum resists many oils, fuels, and coolants
• Suitable for both liquid and gas applications requiring high flow
• Not intended for use with incompatible corrosive chemicals without verification

How is the splitter installed and what fittings are compatible?

Installation follows standard AN plumbing practices: thread the male/female AN fittings until the 37° flare seats, then tighten to recommended torque for AN connections. It accepts 6AN (6AN/AN-6) hoses and fittings on all three ports, providing a straightforward way to split or join lines without hose adapters.

• Thread size: 6AN (9/16-18 UNF) on all ports
• Works with AN-6 hose ends, hardline fittings, and swivel nuts
• Hand-start threads, then torque to AN spec to avoid over-tightening
• Ideal for fuel, oil, coolant, or pneumatic branch lines (verify fluid compatibility)

Who is this for? Builders and technicians who need a compact, durable solution for splitting a single AN-6 feed into two outlets—such as performance vehicle fuel or oil systems, racecar plumbing, custom fabrication projects, and small industrial fluid rigs—will value the EVIL ENERGY 6AN Y block for its high-pressure rating, proven flare sealing, and corrosion-resistant finish. It’s for anyone requiring a precise, repeatable AN split where space is limited and reliability matters.
