Merit Brass 4004-7200 Ss Pipe Nipple 1/4 in Sch 40

Product Description

The MERIT BRASS 4004-7200 is a welded stainless steel pipe nipple sized at 1/4 inch nominal pipe size, manufactured to Schedule 40 wall thickness and dual-certified to Grade 304 and 304L stainless steel. This nipple is used to extend or connect threaded pipe runs in systems where corrosion resistance and durability are required. The 304/304L dual certification means it meets both standard and low-carbon requirements, making it suitable for welded assemblies and installations where post-weld corrosion resistance matters. Plumbers and pipefitters install this fitting in water, steam, gas, and industrial fluid systems.

This pipe nipple is appropriate for residential and commercial plumbing, HVAC hydronic systems, compressed air lines, and light industrial piping applications. Its 1/4 inch size fits smaller branch lines and instrumentation connections. Schedule 40 wall thickness provides adequate pressure-handling capability for typical service conditions in these applications. It is installed using standard NPT threaded connections on both ends.

Key Features

• Welded construction with 304/304L dual-grade stainless steel for corrosion resistance
• 1/4 inch nominal pipe size for small-bore threaded connections
• Schedule 40 wall thickness for standard service pressure ratings
• Low-carbon 304L grade supports weld-area corrosion resistance
• NPT threaded ends for straightforward installation into standard threaded fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4 inch NPT threaded pipe systems requiring Schedule 40 stainless steel components.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or local mechanical code requirements. Shut off the water, gas, or fluid supply and relieve system pressure before disassembling any threaded connections. Use appropriate thread sealant or PTFE tape rated for the service fluid on all NPT threads. Do not over-tighten threaded stainless fittings, as galling can occur without proper lubrication or anti-seize compound.
