Groco 90 Degree Bronze Elbow Fitting, 3/4 Inch Pipe to Hose, PTHC-750

The Groco PTHC-750 is a 90 degree bronze elbow fitting designed to connect 3/4 inch pipe thread to 3/4 inch hose in marine plumbing systems. It is commonly used in thru-hull and strainer installations where a sharp directional change is needed between a threaded pipe fitting and flexible hose, allowing the hose run to turn a corner without kinking or placing strain on the connection. Constructed from bronze, the PTHC-750 resists corrosion in both saltwater and freshwater environments, making it suitable for below-the-waterline plumbing such as raw water intake, cooling, and drainage lines. The 90 degree angle lets installers route hose around tight spaces in an engine compartment or bilge while keeping a rigid, threaded connection on the pipe side. As a simple, single-piece fitting, it requires no assembly and installs with standard pipe fittings and hose clamps. Its compact size and bronze construction make it a durable, long-term component for marine plumbing runs that need a reliable 90 degree pipe-to-hose transition.
