Merit Brass NIPBR112-312 Pipe Nipple 1-1/2 Inches X 3-1/2 Inches Brass Mnpt Sch 40 Seamless Domestic

Product Description

The Merit Brass NIPBR112-312 is a 1-1/2 inch nominal brass pipe nipple designed for use in a wide range of plumbing, HVAC, and industrial piping systems. This nipple measures 3-1/2 inches in length and features male NPT (MNPT) threads on both ends, making it a close-coupling connector that joins two female-threaded fittings or valves in a straight line. Built to Schedule 40 standard wall thickness, this nipple handles the pressure demands common in commercial and residential plumbing installations. The seamless brass construction means there are no weld seams to weaken the fitting under pressure or temperature stress. Brass is a preferred material in plumbing and fluid systems because it resists corrosion, stands up to dezincification, and remains durable across a broad temperature range. Plumbers, pipefitters, and HVAC technicians regularly rely on brass nipples like this one for water supply lines, steam systems, compressed air applications, and gas piping where code permits. The MNPT thread form is the North American standard for tapered pipe threads, ensuring a reliable, leak-resistant seal when used with appropriate thread sealant or PTFE tape. This nipple is domestically produced, which meets sourcing requirements for projects subject to Buy American provisions or contractor specifications that demand domestic content. At 1-1/2 inches nominal pipe size, this fitting works with standard 1-1/2 inch pipe and fittings across all major brands. The 3-1/2 inch length provides a short extension or offset between two fittings, useful when standard close nipples are too short but a long nipple would waste space. Keep this SKU stocked for common repair work, new construction rough-in, and mechanical room installations.
