Merit Brass NIPBR18-3 Brass Pipe Nipple 1/8 Inch X 3 Inch Sch 40 Mnpt Seamless Domestic

Product Description

The Merit Brass NIPBR18-3 is a 1/8 inch by 3 inch brass pipe nipple built for reliable threaded connections 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 equipment. The seamless construction eliminates weld seams, which reduces the risk of weak points and leak paths under pressure. Rated to Schedule 40 standard wall thickness, it meets the demands of commercial and residential plumbing installations where consistent pressure performance is required. Brass is the preferred material for pipe nipples used in water supply lines, gas distribution, compressed air systems, and heating applications. It resists corrosion from moisture and mild chemicals, holds threads cleanly, and works well with a wide range of compatible fittings including brass, copper, and bronze components. The 1/8 inch nominal size makes this nipple well suited for low-flow or instrument connections, gauge ports, pilot lines, and small-diameter branch lines. At 3 inches in length, it provides enough extension to clear fittings and valves without requiring additional couplings. Domestic manufacturing means this nipple meets North American material and dimensional standards, which matters for jobs requiring verified sourcing. MNPT threading conforms to American standard tapered pipe thread specifications, ensuring a tight, pressure-rated seal when used with thread sealant tape or compound. Plumbers, pipefitters, HVAC technicians, and maintenance professionals rely on brass nipples like the NIPBR18-3 for long service life and easy installation. Whether you are building a new piping system or replacing a corroded or damaged nipple in an existing line, this Merit Brass fitting delivers consistent, code-compliant performance.
