Merit Brass NIPBR4-4 Brass Pipe Nipple 4 Inch X 4 Inch Mnpt Sch 40 Seamless Domestic

Product Description

The Merit Brass NIPBR4-4 is a 4 inch nominal brass pipe nipple with a 4 inch overall length, manufactured to Schedule 40 standard wall thickness. This fitting connects two female-threaded pipe fittings or components using its male NPT threads on both ends. It is a close-style nipple commonly used in plumbing, HVAC, industrial piping, and fluid distribution systems where a short, rigid threaded connection is required between two points. The MNPT thread pattern is the standard tapered thread used throughout North American trade plumbing and gas piping systems, making this nipple compatible with the vast majority of valves, tees, elbows, and other fittings found in residential and commercial applications. Brass is a preferred material for pipe nipples in potable water, gas, compressed air, and hydronic heating systems because it offers strong corrosion resistance, good machinability, and reliable sealing under pressure. This nipple is produced using a seamless construction method, which means there is no weld seam along the body. Seamless pipe nipples are stronger and more uniform than welded alternatives, making them the preferred choice in high-pressure and high-temperature service conditions. The Schedule 40 wall thickness rating meets standard specifications for residential and light commercial plumbing installations. This nipple is domestically manufactured, meeting the requirements of projects that carry Buy American provisions or require traceable domestic material sourcing. Plumbers, pipefitters, HVAC technicians, and mechanical contractors rely on brass nipples like the NIPBR4-4 when assembling copper-to-threaded transitions, water heater connections, boiler piping, and gas line assemblies. The 4 inch pipe size and 4 inch length make this a practical choice for applications where a standard hex nipple would be too short and a longer close nipple is needed to bridge a small gap between fittings.
