Merit Brass NIPBR38-312 Pipe Nipple 3/8 Inch X 3-1/2 Inch Brass Mnpt Sch 40 Seamless Domestic

Product Description

The Merit Brass NIPBR38-312 is a 3/8 inch x 3-1/2 inch brass pipe nipple designed for demanding plumbing, HVAC, and industrial piping applications. A pipe nipple is a short length of pipe with male NPT threads on both ends, used to connect two fittings, valves, or other threaded components in a piping system. This nipple features Male National Pipe Taper (MNPT) threads on both ends, which create a secure, leak-resistant seal when assembled with matching female NPT fittings. The nominal pipe size is 3/8 inch, and the overall length measures 3-1/2 inches, making it a practical close extension for tight piping layouts where a standard-length nipple is required. Built to Schedule 40 and Standard (STD) wall thickness specifications, this nipple delivers the structural integrity needed for moderate-pressure water, gas, steam, and fluid systems. Brass is the material of choice for many trade professionals because it resists corrosion, handles a wide range of temperatures, and machines cleanly for reliable thread engagement. This nipple is manufactured seamlessly, meaning there is no weld seam along the body, which improves pressure integrity and reduces the risk of failure at stress points. It carries a domestic designation, indicating it is made in the United States and meets the quality standards expected on commercial and industrial job sites. Plumbers, pipefitters, HVAC technicians, and mechanical contractors use brass MNPT nipples like this one in water supply lines, compressed air systems, gas distribution, and hydronic heating systems. The red finish is a standard indicator used to identify brass pipe fittings in many supply houses. This is a dependable, code-friendly component for any threaded piping assembly.
