EVIL ENERGY 6AN Y-Block Splitter Adapter — Dual 6AN Male Parallel Outlet, Black Anodized 6061-T6, 1500 PSI

The EVIL ENERGY 6AN Male to Parallel Exit Dual 6AN Male Y Block is a black-anodized 6061-T6 aluminum splitter that divides one 6AN line into two parallel 6AN outlets for oil, fuel, coolant, air, or other fluids.

This compact Y-block fitting is engineered to let you branch a single 6AN feed into two identical 6AN male outputs while maintaining a 37° AN sealing angle and high working pressure capacity. Finished in durable black anodize, it resists oil, rust, and corrosion and is sized to work across a wide temperature range. It’s a straightforward mechanical solution when you need parallel fluid distribution without extra bulk or complex plumbing.

How does this adapter split fluid flow without leaks?

The EVIL ENERGY Y-block uses AN-standard geometry and seals at a 37-degree flare angle to ensure a secure metal-to-metal connection when used with matching 6AN fittings. The part is machined from 6061-T6 aluminum for precise threads and faces that meet AN tolerances.

• Thread size: 6AN (9/16-18 UNF).
• Sealing: 37° AN flare mating surface on each AN end.
• High-precision machining for leak-resistant fit.

What operating conditions can this 6AN Y fitting handle?

Designed for demanding automotive and industrial environments, the adapter is rated to 1500 PSI and works over a wide temperature span from -40°F to 250°F. The black anodized finish provides added corrosion resistance for long-term use in harsh conditions.

• Max working pressure: 1500 PSI.
• Temperature range: -40°F to 250°F.
• Surface finish: black anodize for oil and corrosion resistance.

Which fluids and systems are compatible with this EVIL ENERGY Y block?

The part is suitable for most common automotive and light-industrial media, including oil, fuel, coolant, water, air, and many gases. Use it wherever AN fittings are appropriate and the media is chemically compatible with aluminum and anodize.

• Compatible media: oil, fuel, coolant, water, air, gas, and similar fluids.
• Not for incompatible corrosive chemicals without verification.
• Intended for liquid or gas parallel splitting applications.

How do I install and size this Y block correctly?

Match the adapter to 6AN (9/16-18 UNF) hoses or fittings and tighten to recommended AN torque specs for metal-to-metal flare connections. Inspect mating flares and threads for damage, and use compatible fittings to maintain the 37° sealing geometry.

• Ensure mating fittings are 6AN with 37° flare.
• Hand-start threads, then torque to spec to avoid cross-threading.
• Confirm no debris in lines before installation to protect seals.

Who is this for: This EVIL ENERGY 6AN male-to-parallel-exit Y block is aimed at mechanics, motorsport tuners, fabricators, and hobbyists who need a compact, durable splitter for oil, fuel, coolant, or air systems. It’s a practical choice when you need to duplicate a feed line without adding complex manifolds — ideal for uprated cooling loops, secondary fuel feeds, vacuum or boost distribution, and other applications that use AN fittings.
