GROCO 1" NPT Bronze 45 Degree Pipe to 1" Hose

The GROCO 1" NPT Bronze 45 Degree Pipe to 1" Hose fitting is a marine-grade plumbing adapter engineered for fluid transfer systems where durability and corrosion resistance are critical. Built from C83600 bronze and rated UL 647B, this 45-degree male NPT x hose connection delivers reliable performance in high-flow applications aboard vessels, offshore equipment, and industrial fluid distribution networks.

The 1-inch NPT male thread interfaces with standard 1-inch ID hose, enabling seamless integration into existing plumbing configurations. C83600 bronze composition provides superior corrosion resistance in saltwater and brackish environments—a critical advantage over standard brass in marine duty. The standard-flow design minimizes pressure drop while maintaining structural integrity under sustained operating conditions. Note that C83600 bronze fittings do not meet NSF-61 standards and are unsuitable for potable water systems; they are purpose-built for seawater cooling loops, bilge discharge, raw-water intakes, and industrial transfer applications where potability is not a requirement.

This fitting targets marine engineers, yacht systems installers, and industrial maintenance personnel who require proven bronze fittings for salt-air environments. The 45-degree orientation accommodates spatial constraints in engine rooms and confined plumbing spaces where 90-degree elbows cannot be fitted. Compact dimensions (3 x 2 x 3 inches) and minimal weight (0.4 lbs) ease installation without adding significant stress to mounting points or hose runs. GROCO's reputation in marine plumbing systems ensures this component meets the durability standards expected in commercial and recreational vessel applications.
