A and M Industries

A&M Industries specializes in nylon marine plumbing fittings and hose fittings, including hose-to-pipe adapters, pipe elbows, hex pipe plugs, tee fittings, unions, couplers, and reducers. Their catalog covers male, female, and combination configurations across a wide range of sizes from 1/8" to 2".

Nylon and other synthetic composites resist corrosion in both freshwater and saltwater environments, making them a practical alternative to metal fittings in many onboard plumbing systems. They are lightweight, durable, and well-suited for potable water, raw-water, and drain applications where galvanic corrosion between dissimilar metals is a concern.

Match the fitting's pipe thread size (NPT) to your existing pipe or hose diameter. A&M Industries fittings are available in common sizes ranging from 1/8" to 2". For hose-to-pipe adapters, confirm both the hose inner diameter and the pipe thread size before ordering to ensure a leak-free connection.

Yes, A&M Industries nylon fittings use NPT (National Pipe Taper) threads, the U.S. standard for tapered pipe connections. NPT threads are not interchangeable with BSP (British Standard Pipe) fittings, which use a different thread angle and pitch, so always confirm your existing plumbing standard before purchasing.

A&M Industries was established in 1984, originally as a small hardware store. Over the decades the company evolved into a major industrial distributor focused on the marine market, developing an expanding line of nylon marine plumbing and fittings to meet the demands of boat builders, refitters, and marine technicians.
