GROCO Bronze Pipe to Hose Fitting - NPT Pipe to Hose Barb Adapter, Available in 1" to 1-1/4"

The GROCO Bronze Pipe to Hose Fitting is a straight adapter that transitions a standard NPT pipe thread connection to a barbed hose end, letting you join rigid pipe-threaded fittings, seacocks, valves, and thru-hulls to standard marine hose. Cast from solid bronze, these fittings resist corrosion and galvanic wear in continuous saltwater and freshwater service, making them a dependable choice anywhere a boat's plumbing transitions from threaded pipe to flexible hose.

Each fitting is a single-piece design with NPT male threads on one end and a barbed hose shank on the other, sized so the barb OD matches the ID of the hose it is paired with. Use these fittings for raw water intake and discharge lines, bilge pump plumbing, livewell and washdown systems, engine cooling circuits, and any other below-the-waterline or pressurized line where a secure, corrosion-resistant pipe-to-hose transition is required.

Sizes & Options

These fittings are sold by size, and the pipe thread size always matches the hose barb size on the same fitting -- there is no mixed-size version. Match the size to the existing NPT-threaded port (seacock, valve, or thru-hull) you are connecting to, then confirm your hose's inside diameter matches the barb size before ordering. The 1 Inch version suits 1 inch NPT ports and 1 inch ID hose, while the 1-1/4 Inch version suits 1-1/4 inch NPT ports and 1-1/4 inch ID hose. Always secure the hose end with two stainless hose clamps for a double-clamped, code-compliant connection below the waterline.
