Racedom Male Y Block Fitting Splitter AN-10
Designed for high-flow systems, the Y-block configuration allows smooth fluid splitting or merging while maintaining stable pressure and unrestricted volume. Constructed from robust anodized aluminum, it delivers superior strength, heat resistance, and leak-free sealing with 37° AN flare connections. Engineered for demanding performance environments, the AN10 Male Y-Block Fitting provides exceptional reliability and efficiency, making it a critical solution for advanced fuel, oil, and coolant routing needs.
AN10 Male Y-Block Fitting Splitter Adapter – Precision Aluminum Hose Tee Fitting
The AN8 Male Y-Block Fitting Splitter Adapter is a robust, CNC-machined connector designed to divide or merge fluid flow between two separate lines with exceptional efficiency. Engineered for performance automotive plumbing, this Y-shaped adapter provides a clean, unrestricted routing solution in systems requiring multi-feed distribution, balanced return flow, or dual accessory outputs.
Key Features
Premium Construction
-
Built from 6061-T6 aircraft-grade aluminum, offering outstanding durability while remaining lightweight.
-
Protected with a hard anodized coating (commonly satin black) to resist oxidation, chemical exposure, and engine bay heat.
-
CNC machining ensures precision sealing, tight tolerances, and reliable long-term performance.
Optimized Y-Splitter Geometry
-
Allows a single AN8 line to branch into two equal flow paths, or the ability to combine two feeds cleanly into one.
-
Minimizes fluid turbulence and pressure drop compared to sharp-angle tee adapters.
-
Ideal for high-volume fuel, coolant, and oil delivery in tuned powertrains.
AN Thread Compatibility
-
Features standard AN-10 (Army/Navy) 37° flare threaded male ends.
-
Leak-proof under vibration, heat cycles, and elevated line pressure.
-
Seamlessly compatible with aftermarket hose ends, billet rails, regulators, surge tanks, catch cans, and cooling accessories.

Applications
Automotive Performance
-
High-flow fuel system distribution (feed to dual rails, return to tank)
-
Turbocharger oil feeds (dual wastegate oiling, split lubrication)
-
Coolant auxiliary routing (header tank, turbo cooling loops)
-
PCV / vacuum reference circuits on boosted engines
Motorsport / Marine / Aviation
-
Corrosion-resistant design suitable for race fuel, ethanol, and oil-rich environments
-
Ideal where packaging constraints require compact branching
Industrial Fluid Handling
-
Chemical transfer loops
-
Low-volume hydraulic distribution
-
Pneumatic splitters
Benefits
-
Clean Engine Bay Layout: Eliminates unnecessary hoses and sharp routing angles
-
Reliable Sealing: AN 37° flare ensures zero seepage under vibration
-
High Flow Capacity: AN10 passages support larger displacement engines and high-HP fuel systems
-
Lightweight & Durable: Resists fatigue, corrosion, and thermal cycling
-
Professional Look: Anodized finish complements performance builds
Installation Tips
-
Always clean sealing surfaces before assembly.
-
Use AN-specific aluminum wrenches to prevent scratching the anodized finish.
-
Do not overtighten — flare geometry performs the sealing.
-
After installation, pressure test the system at low load before full operation.
