Merit Brass 3012-450 Brass Pipe Nipple 3/4 Npt 4.5 in

Product Description

The MERIT BRASS 3012-450 is a chrome-plated red brass pipe nipple threaded on both ends, designed for connecting sections of pipe in water supply, plumbing distribution, and fluid handling systems. Measuring 4.5 inches overall length with 3/4 inch NPT threads, this nipple provides a full-thread connection at each end for a secure, leak-resistant joint. The red brass construction offers good resistance to dezincification and corrosion, making it well-suited for potable water and general plumbing service. The chrome plating adds surface protection and a clean finished appearance. Licensed plumbers and pipefitters are the primary installers of this fitting in both new construction and retrofit applications.

This nipple is used in residential and light commercial plumbing systems wherever a 3/4 inch NPT threaded connection is required. Common applications include water supply branch lines, fixture connections, boiler trim, and general pipe assembly work. The 4.5 inch length suits installations that need a short extension or offset between fittings, valves, or equipment ports. The NPT taper thread form is the standard used throughout North American plumbing and HVAC piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before making or breaking any threaded connections. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly. Do not overtighten threaded brass fittings, as this can crack the fitting body or damage mating threads.
