Merit Brass 4004-2400 Stainless Steel Pipe Nipple 1/4 in Sch 40

Product Description

The MERIT BRASS 4004-2400 is a welded stainless steel pipe nipple designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. Sized at 1/4 inch nominal pipe size and rated to Schedule 40 wall thickness, this nipple provides a reliable threaded connection point between valves, fittings, and equipment. The Grade 304/304L dual-certified stainless steel construction offers solid corrosion resistance across a wide range of service environments. Licensed plumbers, pipefitters, and HVAC technicians use nipples like this for both new construction and retrofit applications where stainless is specified by code or process requirements.

This nipple is suited for residential and light commercial plumbing, hydronic heating, refrigeration piping, and general industrial fluid handling where stainless steel threaded fittings are required. Its Schedule 40 wall thickness meets standard pressure-rating requirements for typical low-to-medium pressure service lines. The 1/4 inch pipe size makes it a common connector for instrumentation ports, gauge connections, small-diameter branch lines, and control circuit tubing.

Compatibility

Designed as an OEM-style replacement or standard component for threaded 1/4 inch Schedule 40 stainless steel pipe systems using NPT connections.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following IPC and applicable local code requirements. Depressurize and drain the line before removing or installing any threaded nipple. Apply an appropriate thread sealant or PTFE tape rated for stainless steel and the intended service fluid. Do not over-torque threaded connections on stainless fittings, as galling can occur without proper lubrication or anti-seize compound.
