Southwire N-350800 Conduit Nipple 3.5 X 8 Inches Galvanized

Product Description

The SOUTHWIRE N-350800 is a galvanized steel conduit nipple used to extend a length of threaded rigid or IMC conduit. At 3.5 inches trade size and 8 inches in length, this nipple provides a short, threaded coupling segment between conduit sections or at enclosure entries. The galvanized steel construction delivers low conductivity, high corrosion resistance, and secure, lasting thread engagement. Licensed electricians and conduit installers rely on this nipple in commercial, industrial, and residential rough-in work where a close or short extension is needed between boxes, panels, or fittings.

This conduit nipple is suited for use with threaded rigid metal conduit and IMC systems. Typical applications include panel knockouts, junction box extensions, and equipment connections where a short threaded segment is required. The 3.5-inch trade size fits larger conduit runs common in commercial electrical distribution and industrial installations. This nipple is UL listed, making it appropriate for use in installations governed by NEC requirements.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC Article 344 for rigid metal conduit or Article 342 for IMC. De-energize all circuits in the affected conduit run before beginning work. Use appropriate conduit threading tools and listed thread-seal compounds where required by the installation environment. Inspect threads on both the nipple and mating fittings before assembly to ensure proper engagement and prevent cross-threading.
