Merit Brass 6004-1800 Ss Pipe Nipple 1/4 in 316 316L Sched 40

Product Description

The MERIT BRASS 6004-1800 is a 1/4 inch Schedule 40 stainless steel pipe nipple constructed from Grade 316/316L stainless steel using a welded fabrication method. This fitting is used to connect or extend threaded pipe runs in systems that require reliable corrosion resistance and pressure integrity. The dual-grade 316/316L designation means the material meets both standard and low-carbon requirements, making it suitable for applications where weld decay and intergranular corrosion are concerns. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers. At 0.61 pounds, it is a compact fitting suited for tight installations.

This pipe nipple is used in residential and commercial plumbing, process piping, chemical handling, and HVAC hydronic systems where threaded stainless steel connections are required. The 1/4 inch pipe size fits standard NPT threaded fittings and valves. Schedule 40 wall thickness provides adequate pressure ratings for typical service water, steam, and mild chemical applications. It is especially well-suited for environments where carbon steel would corrode, including marine, food service, and chemical processing installations.

Key Features

• Grade 316/316L stainless steel for superior corrosion resistance including chloride environments

• 1/4 inch NPT pipe size fits standard threaded fittings and valves
• Dual 316/316L designation satisfies both standard and low-carbon material specifications
• Compact and lightweight at 0.61 pounds for use in confined spaces

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and ASME B31 piping code requirements. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply a PTFE thread sealant or pipe-grade thread compound rated for stainless steel to all male NPT threads before assembly. Avoid over-torquing stainless steel threaded connections, as galling can occur if threads are driven together under excessive force without proper lubricant.
