The 3/8in-1/4in pipe bushing black from AEROQUIP is a precision adapter fitting engineered for hydraulic and fluid transfer systems in automotive applications. This fitting serves a critical role in custom fuel systems, brake line assemblies, and engine modification projects where downsizing or upsizing fluid pathways is essential. Whether you're building a high-performance fuel injection setup or reconfiguring a classic car's brake system, this bushing allows you to transition between different NPT thread sizes without compromising system integrity or introducing leak points.
Constructed from aluminum and finished in black anodize, the 3/8in-1/4in pipe bushing features a 3/8 inch NPT male inlet and 1/4 inch NPT female outlet, allowing controlled flow reduction through a stepped internal passage. The anodized finish resists corrosion and oxidation in engine bays and under-vehicle environments, critical for durability in high-vibration automotive settings. This fitting maintains full hydraulic compatibility while the compact design (2.35 x 1.15 x 3.9 inches) fits tight engine compartments and custom plumbing layouts without adding bulk or requiring additional bracket support.
Mechanics and fabricators working on fuel system upgrades, turbo installations, and hydraulic brake conversions rely on AEROQUIP bushings for their precision threads and leak-free sealing. The NPT (National Pipe Thread) standard ensures compatibility with industry-standard fittings and tubing on both sides of the adapter. Installation requires only a wrench and thread sealant tape or paste; the lightweight aluminum (0.02 lbs) integrates seamlessly into existing systems without adding parasitic weight. This fitting is ideal for anyone consolidating multiple fluid lines or adapting legacy plumbing to modern fuel injection or cooling system demands.
