Reducer Bush 3/8 To 1/4

The Reducer Bush 3/8 To 1/4 (XRP991202) is a precision NPT bushing engineered for marine plumbing systems where flow lines or fuel systems require stepped-down connection points. Built by XRP-XTREME RACING PROD., this aluminum fitting bridges a 3/8-inch male NPT port to a 1/4-inch female NPT inlet, making it indispensable for anglers and boaters who maintain custom cooling loops, fuel distribution networks, or hydraulic pressure systems aboard. Whether you're retrofitting a cabin cruiser's engine cooling system or upgrading a bay boat's fuel delivery circuit, this reducer bushing ensures leak-free, durable connections without requiring additional adapters or compromises on water-tight integrity.

Machined from marine-grade aluminum and finished in blue anodized coating, the Reducer Bush 3/8 To 1/4 provides corrosion resistance essential for saltwater and freshwater environments alike. The anodized layer protects against galvanic attack and oxidation, extending the fitting's service life in high-moisture conditions that challenge standard brass or steel alternatives. NPT (National Pipe Thread) tapered design ensures a hand-tight seal that tightens as pressure increases, eliminating the need for additional sealant compounds on most applications—though PTFE tape remains a best practice for fuel lines and high-pressure systems. At just 0.04 lbs with compact 2.7 x 1.2 x 3.6-inch dimensions, this fitting integrates seamlessly into tight engine compartments without bulk or weight penalties.

Boaters managing aftermarket fuel systems, auxiliary cooling loops, or pressure-fed bilge pump installations will find immediate value in this reducer bushing's universal compatibility. The stepped NPT profile accommodates both legacy marine equipment (which often uses 3/8-inch inlet ports) and modern compact fuel filters or distribution blocks (which feature 1/4-inch outlets), making this a reliable transition piece for mixed-generation engine builds. Installation requires only a wrench on the male side and a pipe wrench or needle-nose pliers on the female port; no specialized tools or exotic sealants are required. Rated for typical marine system pressures up to 150 PSI, this XRP fitting delivers the dependable performance expected from a brand synonymous with high-flow fuel and cooling systems in extreme racing environments.
