Merit Brass NIPBR34-412 Pipe Nipple 3/4 Inch X 4-1/2 Inch Brass Mnpt Sch 40 Seamless Domestic

Product Description

The Merit Brass NIPBR34-412 is a 3/4 inch by 4-1/2 inch brass pipe nipple designed for use in plumbing, HVAC, and industrial piping systems. This nipple features male NPT threads on both ends, making it a standard close connector between fittings, valves, and pipe sections. It is manufactured to Schedule 40 standard wall thickness, which meets the strength and pressure requirements for most commercial and residential applications. The seamless construction means there is no weld seam along the body of the nipple, which improves pressure integrity and reduces the risk of failure at stress points. Brass is the material of choice for many plumbers and pipefitters because it resists corrosion, handles a wide range of temperatures, and forms reliable threaded connections. This nipple is domestically produced, which meets Buy American requirements on government and municipal projects. The 3/4 inch nominal size is one of the most common pipe sizes in plumbing and mechanical systems, used in water supply lines, gas distribution, compressed air, and hydronic heating systems. The 4-1/2 inch length provides enough extension to bridge standard fitting gaps without requiring additional couplings. MNPT threads conform to ANSI and ASME B1.20.1 standards, ensuring compatibility with standard American pipe fittings across brands and applications. Trade professionals including licensed plumbers, HVAC technicians, pipefitters, and mechanical contractors rely on brass nipples like this one for both new installations and repair work. The red brass color is typical of high-copper alloy brass, which offers superior corrosion resistance compared to yellow brass, especially in water systems. Stock this nipple for service vans, maintenance shops, and job site supply.
