1/2 to 3/8 Reducer Bushi

The 1/2 to 3/8 reducer bushing from A-1 PRODUCTS is an essential marine plumbing adapter designed for boaters, anglers, and vessel owners who need to step down hose or fitting diameters on deck systems. Whether you're connecting fuel lines, water delivery systems, or bilge pump discharge tubing, this reducer bushing bridges the gap between incompatible port sizes with precision and reliability. Built for the demanding marine environment, it solves the common problem of mismatched hose fittings without requiring complete system redesign or replacement.

This reducer bushing features a 1/2-inch outer diameter inlet that accepts standard hose barbs or threaded fittings, while the 3/8-inch inner diameter outlet accommodates smaller-gauge hose and tubing common in marine applications. The compact design—measuring just 3.05 inches in length—fits tight spaces in engine compartments and bilge areas where space is at a premium. Weighing only 0.01 pounds, it adds negligible weight while providing durable, corrosion-resistant construction that withstands salt spray, freshwater exposure, and the vibration inherent to boat operations. The precision machining ensures secure connections that maintain integrity under operating pressure, preventing leaks that could compromise your vessel's systems.

Anglers running late-model center consoles, offshore fishing boats, or recreational cruisers will appreciate this adapter's universal compatibility with aftermarket and OEM marine plumbing configurations. It's equally suited for repair work on aging vessels where standardized fittings have corroded or deteriorated, or as preventive maintenance when upgrading fuel delivery and cooling systems. Installation is straightforward—simply insert the appropriate hose sizes over the outer and inner diameters and secure with hose clamps rated for your system's operating pressure. Stock this compact adapter in your marine spares kit for reliable performance on the water, season after season.
