The Merit Brass NIPBR18-212 is a 1/8 inch nominal brass pipe nipple designed for reliable threaded connections in plumbing, HVAC, and industrial piping systems. This nipple measures 2-1/2 inches in length and features Male National Pipe Taper (MNPT) threads on both ends, making it a standard close or extension fitting used to join two female-threaded components. The Schedule 40 standard wall thickness ensures the fitting handles common working pressures found in residential and light commercial applications. Constructed from seamless red brass, this nipple resists corrosion and dezincification better than standard yellow brass, which makes it a preferred choice for water supply lines, fuel gas systems, compressed air, and steam distribution. Plumbers, pipefitters, and HVAC technicians rely on brass nipples like this one because brass machines cleanly, seats well with pipe dope or PTFE tape, and does not rust inside the pipe wall over time. The domestic manufacturing of this Merit Brass nipple ensures compliance with Buy American requirements on qualifying projects and provides consistent dimensional accuracy. Seamless construction means there is no weld seam that could become a weak point under pressure cycling or thermal expansion. The 1/8 inch nominal pipe size fits standard 1/8 inch NPT fittings and valves, commonly found on pressure gauges, instrument taps, pilot burner assemblies, gas valves, and small-bore control lines. This is a drop-in replacement for worn or corroded nipples in tight-clearance installations where thread integrity is critical. Keep this fitting on the service van or in the shop stock for quick repairs and new installations.
The Merit Brass NIPBR18-212 delivers a domestically produced, seamless red brass nipple in a 1/8 inch by 2-1/2 inch size with MNPT threads and Schedule 40 wall thickness, suited for plumbing, HVAC, and instrumentation piping connections.
