Y Adapter Fitting; Size: -12AN In x -10AN x -10A

The Y Adapter Fitting by Vibrant Performance is a precision-engineered hydraulic and pneumatic distribution component designed for high-performance fuel, oil, and coolant line routing. This -12AN in x -10AN x -10AN fitting serves as a critical junction point in custom fuel systems, turbo installations, and competition engine builds where flow control and reliable splitting are non-negotiable. Engineered for demanding applications, this Y-block adapter consolidates inlet pressure and divides output flow into two separate circuits with equal or controlled distribution.

Constructed from aluminum and finished in black anodized coating, this adapter provides superior corrosion resistance and lightweight performance essential for race and street applications. The anodized surface protects against oxidation while maintaining clean aesthetics in engine bays. The -12AN male inlet accepts larger-diameter lines carrying primary flow, while dual -10AN male outlets manage secondary circuits with precision. Vibrant Performance's manufacturing tolerances ensure leak-free assembly when paired with proper AN hose fittings and thread sealant, eliminating reliability concerns common in budget alternatives.

This Y adapter is ideal for fuel system upgrades, dual-fuel-pump configurations, split-flow coolant loops, and turbocharger feed-and-return setups on vehicles requiring sophisticated plumbing architecture. Weighing just 0.22 lbs, installation requires standard -12AN and -10AN hose ends (sold separately) and an AN wrench set for secure assembly. Compatibility extends across most LS, small-block, big-block, and forced-induction platforms where custom line routing prevents OEM-constraint limitations. Professional installers and enthusiasts trust Vibrant Performance fittings for their dimensional accuracy and zero-compromise durability under boost, heat, and vibration.
