GROCO 1/2" NPT x 1/2" or 5/8" ID Bronze Pipe to Hose Straight Fitting

The GROCO 1/2" NPT x 1/2" or 5/8" ID Bronze Pipe to Hose Straight Fitting is a marine-grade connector designed for reliable plumbing in fresh water, waste, and fuel systems on boats of all sizes. This fitting is essential for preventing costly repairs due to corrosion and fitting failures that can occur in marine environments.

Constructed from a durable marine-bronze alloy, this fitting offers superior resistance to saltwater corrosion and galvanic degradation compared to brass or steel alternatives. It features a 1/2" NPT male port that connects to standard boat through-hull fittings and sea cocks, while the hose barb end accommodates either 1/2" or 5/8" interior diameter hoses, ensuring a solid, leak-free transition.

Both cruising sailors and power boaters can rely on GROCO fittings to upgrade aging plumbing or replace failed connections without major repiping. The straight configuration minimizes turbulence and pressure drop, which is critical for maintaining consistent water delivery to engines and cooling systems. Install this fitting with two stainless steel hose clamps for optimal performance.
