Southwire N-350400 Conduit Nipple 3.5x4 in Galvanized Steel

Product Description

The SOUTHWIRE N-350400 is a galvanized steel rigid conduit nipple designed to extend threaded rigid or IMC conduit runs. At 3.5 inches trade size and 4 inches in length, it provides a short, secure threaded connection between conduit sections or fittings. The galvanized steel construction delivers corrosion resistance and low conductivity, making it suitable for both indoor and outdoor electrical installations. Licensed electricians install this fitting as part of a complete conduit assembly. It carries a UL listing, confirming compliance with applicable electrical safety standards.

This conduit nipple is used in commercial and residential electrical installations wherever a close or short nipple is needed to join rigid metal conduit or IMC sections. Typical applications include panel terminations, junction box entries, and conduit body connections. The threaded ends mate with standard rigid conduit fittings and locknuts, making it a routine component in conduit system assemblies across industrial, commercial, and residential wiring projects.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits and verify the system is locked out and tagged out before beginning conduit work. Use appropriate pipe wrenches or conduit tools to thread the nipple snugly into fittings without over-torquing the threads. All conduit system connections should be inspected for continuity of the equipment grounding path after assembly.
