Merit Brass 2124-4800 Brass Pipe Nipple 48 in 1-1/2 Npt

Product Description

The MERIT BRASS 2124-4800 is a full-length red brass pipe nipple threaded on both ends, designed for connecting sections of pipe in plumbing, gas distribution, and industrial piping systems. At 48 inches overall length with 1-1/2 inch NPT threads and a 1-1/2 inch outside diameter, this nipple is suited for runs requiring a long close or extension fitting without additional couplings. Red brass construction provides corrosion resistance in wet, potable water, and mild chemical service environments. Licensed plumbers and pipefitters install this component as part of threaded pipe assemblies in both residential and commercial applications.

This nipple fits standard 1-1/2 inch NPT threaded systems and is appropriate for water supply, low-pressure gas, and general fluid service lines where a 48-inch close nipple is required. The OSHA-compliant rating makes it suitable for regulated commercial and industrial job sites. Typical applications include boiler rooms, mechanical rooms, process piping, and plumbing rough-in where a long threaded nipple replaces a pipe-and-coupling assembly. The 11.52-pound weight reflects the solid red brass material throughout the full 48-inch body.

Key Features

• Full 48-inch overall length eliminates the need for additional couplings in long runs
• Red brass construction resists corrosion in water and mild fluid service

Compatibility

Designed for use in standard 1-1/2 inch NPT threaded piping systems as an OEM-style or aftermarket long nipple for plumbing, gas, and industrial fluid distribution applications.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC and IFGC codes. Shut off the water or gas supply and depressurize the line before threading or removing any fittings. Use appropriate pipe thread sealant or PTFE tape on NPT threads and tighten with a pipe wrench to proper engagement without over-threading. Do not use in systems exceeding the pressure and temperature ratings for red brass threaded fittings.
