Merit Brass 4002-1000 Ss Pipe Nipple 1/8 in Sch 40

Product Description

The MERIT BRASS 4002-1000 is a welded stainless steel pipe nipple designed for use in piping systems that require corrosion resistance and reliable threaded connections. Manufactured from Grade 304/304L stainless steel to Schedule 40 wall thickness, this nipple accepts a 1/8 inch threaded pipe connection on both ends. The 304L dual-grade designation means it meets both standard and low-carbon requirements, making it suitable for applications where weld integrity and corrosion resistance are critical. It is a standard component installed by plumbers, pipefitters, and HVAC technicians building or repairing small-diameter pipe assemblies.

This nipple is suited for residential and light commercial plumbing, HVAC, and process piping installations where a short threaded stainless steel connector is needed. The 1/8 inch pipe size makes it appropriate for instrumentation lines, pilot gas supply, pressure gauge connections, and similar small-bore applications. Its welded construction and 304/304L grade provide resistance to corrosion in both wet and mildly corrosive environments.

Key Features

• Grade 304/304L stainless steel construction for corrosion resistance in wet and mildly corrosive service
• Schedule 40 wall thickness for standard-duty pressure applications
• Welded construction meets typical pipefitting fabrication standards
• 1/8 inch threaded pipe size for small-bore instrument and utility connections
• Dual-grade 304/304L designation satisfies both standard and low-carbon material specs

Compatibility

Designed as an OEM-style replacement or new-install fitting for 1/8 inch Schedule 40 stainless steel threaded pipe systems in plumbing, HVAC, and light process piping applications.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements for the service type. Apply appropriate thread sealant or PTFE tape to the male threads before assembly. Hand-tighten first, then wrench-tighten to avoid cross-threading or over-stressing the fitting. Shut off and depressurize the line completely before removing or installing any threaded fitting.
