Merit Brass 4004-6000 Ss Pipe Nipple 1/4 in Sch 40

Product Description

The MERIT BRASS 4004-6000 is a welded stainless steel pipe nipple designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. Sized at 1/4 inch pipe and built to Schedule 40 wall thickness, this nipple is manufactured from Grade 304/304L stainless steel, offering solid corrosion resistance in a wide range of service environments. It serves as a short threaded connector between fittings, valves, and equipment ports. Licensed plumbers, pipefitters, and HVAC technicians install this type of nipple wherever a close or short extension is needed in a threaded piping run.

This pipe nipple is suited for residential and light commercial applications including water supply lines, compressed air systems, chemical distribution, and HVAC hydronic or steam piping. The 304/304L dual-grade designation makes it compatible with both standard and low-carbon stainless steel system requirements, particularly where welded construction and corrosion resistance are specified. It is a direct fit wherever a 1/4 inch NPT threaded nipple is called for in a Schedule 40 stainless steel system.

Key Features

• Grade 304/304L stainless steel construction provides corrosion resistance in wet and chemical service environments

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC guidelines for threaded pipe assemblies. Shut off and depressurize the system completely before removing or installing any threaded pipe component. Apply a compatible thread sealant or PTFE tape rated for stainless steel and the intended service fluid. Avoid over-tightening, which can stress threaded connections on stainless nipples.
