Merit Brass NIPBR12-4 Brass Pipe Nipple 1/2 Inches X 4 Inches Sch 40 Mnpt Seamless Domestic

Product Description

The Merit Brass NIPBR12-4 is a 1/2 inch by 4 inch brass pipe nipple built for reliable performance in residential and commercial plumbing systems. This nipple features Male National Pipe Taper threads on both ends, making it a standard close-coupled connector used to join two female-threaded fittings or extend a pipe run. It is manufactured to Schedule 40 standard wall thickness, which gives it the strength needed for moderate-pressure water, gas, and fluid systems. The seamless construction means there are no weld seams that could become weak points under pressure or thermal cycling. Brass is a preferred material for plumbers and pipefitters working on potable water lines, fuel gas connections, compressed air systems, and hydronic heating loops. It resists corrosion better than steel in wet environments and holds up well to dezincification when the alloy is properly specified. This nipple is domestically manufactured, which matters on projects where Buy American requirements apply, such as municipal water systems, government facilities, and union job sites. The 4 inch length makes it a useful close nipple for applications where standard close or short nipples are too short and longer pipe sections would be excessive. HVAC technicians use brass nipples like this when connecting boilers, water heaters, and hydronic system components. Plumbers rely on them for shutoff valve installations, fixture supply connections, and manifold assemblies. The MNPT thread pattern is compatible with NPT female fittings across all major brands, ensuring broad interchangeability on the job. At 1/2 inch nominal size, this nipple fits the most common pipe size found in residential and light commercial plumbing.

• 1/2 inch nominal diameter with 4 inch overall length for versatile close-coupled connections
• Schedule 40 standard wall seamless brass construction for strength and corrosion resistance
• Male NPT threads on both ends for compatibility with standard female NPT fittings

Product Highlights

The Merit Brass NIPBR12-4 delivers a domestically made, seamless brass nipple in a Schedule 40 wall that plumbers and HVAC technicians can trust for water, gas, and fluid system connections. Its standard MNPT threading ensures drop-in compatibility with NPT fittings across the trade.
