Merit Brass 3012-800 Brass Pipe Nipple 3/4 Npt 8 in

Product Description

The MERIT BRASS 3012-800 is a chrome-plated red brass pipe nipple designed for threaded piping assemblies in plumbing, HVAC, and mechanical systems. Constructed from red brass with a chrome finish, it measures 8 inches overall length (OAL) with 3/4 inch NPT threads on both ends and a 3/4 inch outside diameter. The full-thread configuration on both ends allows direct connection to fittings, valves, couplings, and other threaded components. This nipple meets OSHA standards and is well suited for applications where corrosion resistance and a finished appearance are required.

This nipple is commonly used in residential and light commercial plumbing, gas, and hydronic piping systems where a short, rigid threaded connection is needed. It is a standard choice for connecting valves, gauges, or fixtures to supply lines and branch piping. The chrome plating makes it appropriate for exposed installations where aesthetics matter, such as under-sink or above-floor plumbing runs. Licensed plumbers and pipefitters are the primary installers in most jurisdictions.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply or isolate the relevant piping section before installation. Apply an approved thread sealant or PTFE tape to NPT threads before making up the joint — do not overtighten, as brass threads can gall or crack under excessive torque. Verify system pressure rating is within the nipple and fitting assembly limits before returning the system to service.
