The Merit Brass NIPBR18-4 is a 1/8 inch nominal, 4 inch length brass pipe nipple designed for reliable performance in plumbing, HVAC, and industrial piping systems. This fitting features Male National Pipe Taper (MNPT) threads on both ends, allowing it to connect securely to female-threaded fittings, valves, and equipment. The nipple is manufactured to Schedule 40 standard wall thickness, making it suitable for moderate to high-pressure applications in water, gas, oil, and air systems. Seamless construction eliminates weld seams, reducing the risk of weak points and improving overall pressure integrity throughout the fitting. Brass is a preferred material among plumbing and HVAC professionals because it resists corrosion, handles a wide range of temperatures, and provides long service life even in demanding environments. This nipple is domestically produced, meeting strict quality standards expected by trade professionals who require consistent, code-compliant components on every job. The 1/8 inch size is commonly used in tight spaces, instrument connections, gauge ports, and low-flow applications where a small-diameter threaded connection is needed. MNPT threads conform to ANSI and ASME B1.20.1 standards, ensuring compatibility with standard fittings across major brands and system types. Whether used in residential plumbing rough-in, commercial HVAC piping, or light industrial fluid handling, this brass nipple delivers the durability and thread integrity that contractors and technicians depend on. The red brass alloy composition provides additional corrosion resistance compared to yellow brass, making it a smart choice for potable water and wet system applications.
The Merit Brass NIPBR18-4 delivers seamless, Schedule 40 brass pipe nipple performance in a compact 1/8 inch by 4 inch form factor. It is built for trade professionals who need reliable, corrosion-resistant threaded fittings for plumbing, HVAC, and fluid system applications.
