Merit Brass 2124-1200 Brass Pipe Nipple 1.5 in Npt 12 in

Product Description

The MERIT BRASS 2124-1200 is a red brass pipe nipple designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. It measures 12 inches overall length (OAL) with 1-1/2 inches NPT threads on both ends and a 1-1/2 inches outside diameter. Machined from red brass, this nipple offers reliable corrosion resistance in water, gas, and general-purpose fluid service applications. Both ends are fully threaded to NPT standards, allowing direct connection to compatible fittings, valves, and pipe sections without modification. Licensed plumbers and pipefitters install this type of nipple as an extension or connector segment in threaded piping runs.

This nipple is suited for residential and light commercial plumbing, hydronic heating, compressed air, and low-pressure gas line installations where red brass is specified. The 1-1/2 inches NPT size is common in main supply lines, manifold connections, and equipment tie-ins. It meets OSHA standards, making it appropriate for job sites with compliance requirements. Plumbers, pipefitters, and HVAC technicians working on boiler rooms, mechanical rooms, or utility piping will find this a standard stocking item.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable local plumbing codes and IFGC requirements for gas service. Shut off water or gas supply and relieve system pressure before removing or installing any threaded pipe component. Apply thread sealant or PTFE tape to NPT threads per the system fluid type before make-up. Do not over-torque threaded connections, as red brass can be damaged by excessive force.
