Merit Brass NIPBR18-312 Pipe Nipple 1/8 Inches X 3-1/2 Inches Mnpt Sch 40 Seamless Brass Domestic

Product Description

The Merit Brass NIPBR18-312 is a seamless brass pipe nipple designed for reliable use in plumbing, HVAC, and industrial piping systems. This nipple measures 1/8 inches in nominal pipe size and 3-1/2 inches in overall length. It features male NPT threads on both ends, making it a standard close-coupled connector used to join two female-threaded fittings or extend a threaded pipe run. The MNPT thread pattern conforms to standard National Pipe Taper specifications, ensuring a leak-resistant, pressure-tight seal when used with thread sealant or PTFE tape. Built to SCH 40 and STD wall thickness ratings, this nipple handles the pressure demands of typical water supply, gas distribution, compressed air, and steam service lines. Brass is a preferred material in plumbing and HVAC work because it resists corrosion, holds up well against dezincification in water systems, and provides strong machinability for clean thread profiles. The seamless construction eliminates weld seams, reducing the risk of weak points along the body of the nipple. This product is domestically manufactured, which is important for projects requiring compliance with Buy American provisions or local material sourcing standards. Plumbers, pipefitters, HVAC technicians, and mechanical contractors routinely use pipe nipples like this to connect valves, gauges, strainers, regulators, and other threaded components in tight spaces. The 1/8 inches size is commonly found in instrument lines, gas pilot lines, and low-flow service connections. Whether used in a new installation or as a replacement in an existing system, the Merit Brass NIPBR18-312 delivers consistent dimensional accuracy and dependable thread engagement that professionals expect on the job.
