Merit Brass 4002-001 Stainless Steel Pipe Nipple 1/8 in Sch 40

Product Description

The MERIT BRASS 4002-001 is a welded stainless steel pipe nipple sized for 1/8 inch pipe connections. Manufactured from Grade 304 and 304L stainless steel, it meets Schedule 40 wall thickness standards, making it suitable for moderate-pressure fluid and gas piping applications. The dual-grade 304/304L designation indicates low carbon content, which reduces sensitization risk in welded assemblies. Plumbers, pipefitters, and HVAC technicians use nipples like this to extend or connect threaded pipe runs in tight or corrosive service environments.

This nipple is well-suited for residential and light commercial plumbing, HVAC piping, and process piping where corrosion resistance is a priority. The 1/8 inch size is commonly found in instrument lines, low-flow supply lines, and control piping. Stainless steel construction makes it appropriate for wet, humid, or chemically active environments where carbon steel fittings would degrade over time.

Key Features

• Grade 304 and 304L dual-certified stainless steel construction for corrosion resistance
• Welded construction to Schedule 40 wall thickness
• 1/8 inch pipe size with matching 1/8 inch thread size
• Low carbon 304L grade reduces weld sensitization risk
• Lightweight at 0.012 pounds per piece, suitable for instrumentation and control line use

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/8 inch threaded Schedule 40 stainless steel pipe systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following IPC and applicable local plumbing codes. Shut off and depressurize the pipe system fully before removing or installing any threaded fitting. Use appropriate thread sealant rated for stainless steel and compatible with the system fluid. Avoid over-tightening threaded connections, as this can stress the fitting body or damage threads.
