Groco Bronze Pipe Nipple, NPT Thru-Hull Fitting - Available in 1-1/4" to 1-1/2"

The Groco Bronze Pipe Nipple is a solid bronze connector used to join thru-hull fittings, seacocks, strainers, and other threaded marine plumbing components into a single continuous below-waterline line. Machined with straight NPT threads on both ends, it provides a corrosion-resistant, reliable connection point for raw water intake and discharge systems where saltwater exposure demands durable materials. Each nipple is cast and machined from marine-grade bronze to resist the pitting and dezincification that plague lesser alloys in continuous seawater service.

Sizes & Options

This pipe nipple is available in 1-1/4 inch and 1-1/2 inch NPT thread sizes. Match the size to the NPT thread size of the thru-hull fitting, seacock, or strainer you are connecting to -- the nipple must thread directly into the existing fitting, so measure the mating component's thread size before ordering rather than the hose or pipe diameter.
