1” Barrel Nipple MM SS | Stainless Steel Male to Male Pipe Connector

The 1” Barrel Nipple MM SS is a heavy-duty stainless steel male-to-male threaded pipe connector designed to securely join two female threaded components in marine, industrial, and commercial plumbing systems. Manufactured from marine-grade SS316 stainless steel, this barrel nipple offers outstanding resistance to corrosion, pressure, vibration, and chemical exposure—making it the perfect choice for harsh marine and offshore environments.

This 1 inch stainless steel barrel nipple is widely used to extend pipe runs, connect valves to pumps, join hose connectors, or link manifolds in engine rooms, seawater systems, cooling circuits, washdown lines, fuel lines, and industrial fluid transfer systems. With precisely machined BSP male threads on both ends, it ensures a tight, leak-free seal when installed with PTFE tape or thread sealant.
