Merit Brass 4540-400 Pipe Nipple 2-1/2 in Sch 80 Ss 304

Product Description

The MERIT BRASS 4540-400 is a seamless stainless steel pipe nipple designed for use in high-pressure and corrosion-resistant piping systems. Manufactured from Grade 304/304L stainless steel and rated to Schedule 80 wall thickness, this nipple provides reliable service in demanding fluid handling, industrial, and mechanical applications. At 2.5 inches pipe size, it suits larger-diameter runs where both strength and corrosion resistance are critical. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting as part of threaded pipe assemblies in both new construction and retrofit work.

This nipple is suited for residential and commercial piping systems requiring stainless steel construction, including potable water, chemical transfer, steam, and process fluid lines. The Schedule 80 wall thickness supports higher working pressures compared to Schedule 40, making it appropriate for utility mechanical rooms, industrial process lines, and applications subject to elevated temperatures or pressures. The 304/304L dual certification provides flexibility across both standard and low-carbon weld-adjacent applications.

Key Features

• Seamless construction eliminates weld seams for uniform wall strength throughout
• Grade 304/304L stainless steel provides corrosion resistance in wet and chemical environments
• Schedule 80 wall thickness supports elevated working pressures versus standard Schedule 40
• 2.5-inch pipe size fits larger-diameter threaded piping systems
• Dual-grade 304/304L certification accommodates low-carbon application requirements

Compatibility

Designed as an OEM-style replacement or new-installation component for 2.5-inch threaded stainless steel piping systems using Schedule 80 fittings and pipe.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and ASME B31 piping codes. Shut off and depressurize the system completely before disassembling any threaded connections. Apply a code-approved thread sealant or PTFE tape rated for stainless steel and the intended service fluid. Avoid over-tightening threaded connections on stainless steel, as galling can occur without proper lubrication or anti-seize compound.
