This 1-1/2" x 5" black malleable steel nipple is a high-strength pipe fitting designed for durable connections in gas, oil, and air supply systems. Engineered from heavy-duty black iron, this nipple is ideal for extending pipe runs or connecting valves in large-scale appliance installations. It is commonly used in gas-fired appliances such as high-capacity water heaters, commercial boilers, and furnace systems where a secure, leak-proof seal is critical. The black finish provides natural resistance to corrosion in non-potable applications, and the precision-cut threads ensure a tight fit with standard NPT plumbing components. Whether you are performing routine maintenance or a new appliance hookup, this malleable steel fitting offers the industrial-grade reliability required for demanding HVAC and plumbing environments.
