Merit Brass 4032-1800 Ss Pipe Nipple 2 in Sch 40 304 304L

Product Description

The MERIT BRASS 4032-1800 is a stainless steel pipe nipple rated for Schedule 40 service, manufactured from Grade 304/304L stainless steel using a welded construction method. Pipe nipples serve as short threaded connectors between fittings, valves, and pipe runs in fluid and gas piping systems. This nipple is sized for 2-inch pipe and weighs 5 pounds, making it suitable for heavier-duty inline connections. Plumbers, pipefitters, and industrial maintenance technicians typically specify Schedule 40 stainless nipples where corrosion resistance is required alongside standard wall strength. The dual-grade 304/304L designation supports both standard and low-carbon welding applications.

This nipple is appropriate for use in residential, commercial, and light industrial piping systems where stainless steel is required to resist corrosion from water, chemicals, or process fluids. Schedule 40 wall thickness makes it a common choice for pressure and drain applications. The 2-inch pipe size fits standard 2-inch threaded fittings and valves used in plumbing and mechanical piping systems. It is well suited for installations in boiler rooms, mechanical rooms, chemical handling lines, and food-service or sanitary environments where iron or carbon steel fittings are not acceptable.

Key Features

• Grade 304/304L dual-certified stainless steel for corrosion resistance and low-carbon weld compatibility
• Welded construction meeting Schedule 40 wall thickness requirements
• 2-inch nominal pipe size for standard threaded fitting connections
• 5-pound unit weight suitable for structural inline connections
• UNSPSC Code 40173300 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or new-install fitting for 2-inch Schedule 40 threaded stainless steel piping systems in plumbing and mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC or ASME B31 piping code requirements for the jurisdiction. Depressurize and drain the system completely before removing or installing threaded nipples. Apply appropriate thread sealant or PTFE tape rated for the service fluid before making up threaded connections. Do not over-torque stainless steel threads, as galling can occur; use a pipe wrench with controlled force and a backup wrench on adjacent fittings.
