GROCO 1-1/2" NPT x 1-3/4" Bronze Full Flow Pipe to Hose Straight Fitting

The GROCO 1-1/2" NPT x 1-3/4" Bronze Full Flow Pipe to Hose Straight Fitting is a heavy-duty plumbing connector engineered for high-flow applications where pressure drop and reliability are critical. Manufactured from C83600 bronze—a corrosion-resistant alloy standard in marine and industrial piping systems—this fitting delivers maximum flow with minimal restriction, making it ideal for seawater systems, fuel transfer, and industrial fluid transfer where conventional restrictive fittings fall short.

This straight fitting features a male NPT (National Pipe Thread) connection on one end and a 1-3/4" hose connection on the other, allowing direct coupling between threaded pipe infrastructure and hose assemblies without intermediate adapters. C83600 bronze provides superior corrosion resistance compared to cast iron or steel in salt-air and moisture-heavy environments, extending service life in demanding conditions. The full-flow design eliminates turbulence and pressure loss, a critical advantage in systems where flow volume directly impacts operational efficiency. UL Listed to standard 647B, the fitting meets recognized safety and performance benchmarks for industrial applications.

Intended users include marine operators, offshore drilling contractors, agricultural equipment manufacturers, and industrial facilities managing fuel, coolant, or water systems. This fitting is not suitable for potable water applications—C83600 bronze does not meet NSF-61 compliance standards required for drinking water systems. Available in sizes ranging from 1/2" to 3", the GROCO line serves varied industrial scaling needs, from small-vessel through-hulls to large industrial pumping stations. The straight configuration is preferred where space permits, offering superior flow characteristics over elbow alternatives.
