Female Y Fitting w/1/8in Port 1/2in & Dual 3/8

The Female Y Fitting with 1/8in Port, 1/2in & Dual 3/8 by Vibrant Performance is a precision hose manifold designed for complex coolant, vacuum, and fluid distribution systems in high-performance automotive applications. This Y-fitting serves as a critical junction point in custom cooling loops, turbo intercooler setups, and vacuum-operated fuel pressure regulators where multiple feed lines must converge at a single takeoff. Whether you're building a custom cooling circuit, integrating auxiliary gauges, or routing secondary vacuum sources, this fitting provides a compact, threaded solution that eliminates the need for multiple separate adapters.

Constructed from brass with precision-machined ports, the Female Y Fitting features a 1/2-inch primary inlet that accepts standard hose barbs or NPT adapters, dual 3/8-inch outlets for balanced flow distribution, and a 1/8-inch secondary port for gauge sensors or pressure transducers. The female threading design allows direct hose barb insertion or adapter coupling without additional fittings, reducing potential leak points and minimizing system complexity. Vibrant Performance's quality control ensures tight tolerances and consistent thread pitch across all ports, critical for maintaining system integrity under boost pressure or high-temperature coolant flow conditions.

Mechanics and engine builders favor this fitting for turbocharger coolant lines, radiator bypass circuits, and intercooler plumbing where three separate flow paths are required. The compact 3.55 x 1.65 x 4.55-inch envelope fits tight engine bay layouts without requiring extensive bracket fabrication. Installation is straightforward: select appropriate hose sizes (1/2-inch for primary, 3/8-inch for secondary outlets), apply thread sealant to NPT connections, and secure hose clamps firmly to prevent vibration-induced leaks during acceleration or deceleration events.
