GROCO Bronze Pipe to Hose Fittings - NPT Pipe Thread to Hose Barb, 1/2" to 1-1/2"

GROCO bronze pipe to hose fittings give you a solid, corrosion-resistant transition between rigid NPT-threaded pipe or fittings and flexible marine hose. Cast from solid bronze, these fittings hold up to years of raw water and saltwater exposure on thru hulls, seacocks, strainers, pumps, and other below-the-waterline plumbing where a reliable, leak-free connection matters. One end threads directly into NPT pipe or fittings; the other end is barbed to accept hose, which is then secured with a properly sized hose clamp.

Sizes & Options

This line is available in two sizes to match different plumbing runs. The PTH-5062 is a compact 1/2 inch NPT fitting that accepts either 1/2 inch or 5/8 inch inside-diameter hose on its barbed end, useful when you need flexibility to match existing hose stock. The PTH-1500 steps up to a 1-1/2 inch NPT to 1-1/2 inch hose barb connection, sized for larger raw water intake or discharge lines. Match the pipe end to your existing NPT thread size and confirm your hose's inside diameter fits the barb before ordering, then secure the connection with two properly sized stainless hose clamps.
