Merit Brass 2120-1200 Brass Pipe Nipple 12 in 1-1/4 Npt

Product Description

The MERIT BRASS 2120-1200 is a red brass pipe nipple threaded on both ends, designed for use in plumbing, HVAC, and industrial piping systems. It measures 12 inches in overall length with a 1-1/4 inch NPT thread standard and a 1-1/4 inch outside diameter. Constructed from red brass, this nipple offers reliable corrosion resistance in water, gas, and general fluid service applications. Licensed plumbers and pipefitters install this type of fitting when connecting threaded pipe runs, extending existing lines, or making up close-coupled assemblies in both residential and light commercial systems.

This nipple suits applications where a full-length threaded brass fitting is required. Its NPT threads make it compatible with standard threaded pipe and fittings across plumbing, hydronic heating, compressed air, and low-pressure gas piping installations. The 1-1/4 inch size is commonly used in branch lines, riser sections, and manifold connections where moderate flow capacity is needed. The red brass alloy is well suited to potable water service and mildly corrosive fluid environments.

Key Features

• Threaded on both ends for easy make-up into standard NPT fittings
• 12 inch overall length suits extension and offset piping runs
• 1-1/4 inch NPT thread standard for broad system compatibility
• Red brass construction provides corrosion resistance in water and fluid service
• Meets OSHA standards

Compatibility

Designed as an OEM-style replacement and general-use fitting for standard 1-1/4 inch NPT threaded piping systems in plumbing, HVAC, hydronic, and light industrial applications.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the NPT threads before make-up. Tighten fittings to a firm, leak-free connection using a pipe wrench — do not overtighten, as this can crack fittings or damage threads.
