Merit Brass 2120-1000 Brass Pipe Nipple 1-1/4 in Npt 10 in

Product Description

The MERIT BRASS 2120-1000 is a red brass pipe nipple designed for use in threaded piping systems across plumbing, HVAC, and industrial applications. At 10 inches overall length with 1-1/4 inches NPT threads on both ends, this nipple serves as a straight pipe extension between fittings, valves, or equipment ports. Constructed from red brass, it offers strong corrosion resistance in water, steam, and low-pressure gas service. At 2.42 pounds, it is a solid, full-size nipple suited for both new installation and field repair work. Licensed plumbers and pipefitters are the typical installers, though HVAC technicians also use brass nipples frequently in equipment connections.

This nipple is appropriate for residential and light commercial piping installations where a 1-1/4 inches NPT threaded connection is required. Common applications include water distribution lines, boiler piping, hydronic heating systems, gas supply connections, and service connections on HVAC equipment. The 10 inches length makes it useful for bridging moderate gaps between pipe runs or between valves and equipment flanges. It meets OSHA standards, making it suitable for use in regulated work environments.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC or IFGC code requirements. Shut off and depressurize the line before removing or installing any threaded pipe component. Apply an appropriate thread sealant or PTFE tape to the NPT threads before assembly. Do not over-tighten threaded connections, as over-torquing brass fittings can cause cracking.
