Brass Threaded Hexagon Nipple — IMPA 732351-732359

On cargo ships, container vessels, tankers and offshore support vessels, the brass threaded hexagon nipple is a go-to fitting for joining two female-threaded pipe ends in low-pressure water, air and hydraulic lines. It is commonly found in engine-room cooling circuits, fresh-water and sanitary piping, compressed-air distribution and deck washdown systems. The hexagon body allows a standard open-end or adjustable wrench to be applied without removing adjacent pipework, which saves time during maintenance and refits. When a reliable, corrosion-resistant joint is needed in confined machinery spaces, this nipple provides a secure, leak-tight connection.

Manufactured from high-quality brass, the fitting resists corrosion from seawater atmosphere, bilge water and many industrial fluids. The hexagon design offers a firm grip for tightening and prevents the nipple from turning when the mating fittings are made up. Available across nine IMPA-coded variants — 732351 through 732359 — the series covers a range of thread sizes to suit common shipboard pipe diameters. Each code is ordered and priced individually, so purchasing officers can specify exactly the size required without buying a full set. Brass construction also makes the nipple suitable for use in potable-water and pneumatic systems where non-sparking, non-magnetic properties are beneficial.
