It features a 3-inch nominal pipe size and a 4-inch overall length, with male NPT (MNPT) threads on both ends for straightforward installation into standard threaded fittings and valves. The nipple is manufactured to SCH 40 standard wall thickness, which meets the demands of a wide range of residential, commercial, and light industrial applications. Brass construction provides excellent resistance to corrosion, dezincification, and scale buildup, making this nipple a dependable choice for water supply lines, steam systems, gas distribution, and compressed air piping. The seamless design eliminates weld seams, which reduces the risk of weak points or leaks under pressure. This domestic-made fitting complies with applicable standards for brass pipe fittings, giving contractors and plumbers confidence in the material quality and dimensional accuracy. MNPT threads are machined to NPT standards, ensuring a proper seal when used with thread sealant tape or compound. Pipe nipples like this one are commonly used to extend pipe runs, connect two female-threaded fittings, or close the distance between valves and other components in a system. The 3-inch size is widely used in larger commercial plumbing and HVAC installations, boiler rooms, mechanical rooms, and process piping. Trade professionals including plumbers, pipefitters, and HVAC technicians rely on brass nipples for their long service life and ease of installation. The Merit Brass NIPBR3-4 delivers consistent thread quality and wall thickness that meets schedule 40 requirements, making it a practical stock item for supply houses and contractors handling medium to large diameter pipe work.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e3-inch nominal size with 4-inch overall length for medium to large diameter piping applications\u003c\/li\u003e\n\u003cli\u003eSeamless brass construction resists corrosion, scale, and dezincification in water, gas, and steam service\u003c\/li\u003e\n\u003cli\u003eSCH 40 standard wall thickness with MNPT threads on both ends for reliable, leak-free connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Merit Brass NIPBR3-4 is a domestically produced, seamless brass pipe nipple built to SCH 40 standards.
