Merit Brass 6020-4800 Ss Pipe Nipple 1-1/4 in Grade 316 Sch 40

Product Description

The MERIT BRASS 6020-4800 is a welded stainless steel pipe nipple sized for 1-1/4 inch pipe, manufactured from Grade 316 and 316L stainless steel to Schedule 40 wall thickness. Pipe nipples are short threaded sections of pipe used to connect two female-threaded fittings or valves in a piping run. The 316/316L dual-grade designation indicates compliance with both standard and low-carbon variants, offering improved weld integrity and resistance to intergranular corrosion. This nipple is suited for plumbing, industrial, and mechanical piping systems where corrosion resistance, strength, and pressure-rated performance are required. Licensed plumbers and pipefitters are the typical installers.

This nipple is used in residential and commercial piping systems handling water, steam, mild chemicals, and other corrosive media where carbon steel or standard 300-series stainless would be inadequate. Grade 316 stainless provides enhanced resistance to chlorides and acidic environments, making this nipple a common choice in coastal installations, chemical processing lines, food-service plumbing, and marine applications. The Schedule 40 wall rating ensures compatibility with standard pressure-rated piping systems across a wide range of mechanical and plumbing applications.

Key Features

• Grade 316 and 316L dual-certified stainless steel for superior corrosion resistance
• Welded construction to Schedule 40 wall thickness for standard pressure-rated service
• 1-1/4 inch pipe size fits standard NPT threaded fittings and valves
• Low-carbon 316L designation supports weld-zone corrosion resistance
• Suitable for corrosive, chloride-rich, or sanitary piping environments

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1-1/4 inch NPT threaded piping systems using Schedule 40 pipe and fittings.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements for the service environment. Shut off and depressurize the affected piping system before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the media being conveyed. Do not overtighten threaded connections, as stainless steel threads are susceptible to galling.
