Thomas Betts 1951 Conduit Nipple 4 in Rigid Imc Malleable Iron

Product Description

The THOMAS BETTS 1951 is a malleable iron conduit nipple designed for use with rigid metal conduit and intermediate metal conduit (IMC) systems. It features a threaded connection type and an insulated interior to protect wire insulation at the fitting entry point. The 4-inch trade size accommodates larger conduit runs common in commercial and industrial electrical installations. Licensed electricians and electrical contractors install this fitting as part of conduit assembly in non-hazardous locations. Its malleable iron construction provides durability and reliable thread engagement in demanding wiring system applications.

This nipple is suited for rigid conduit and IMC installations in non-hazardous areas, including commercial buildings, industrial facilities, and similar environments where 4-inch trade size conduit is specified. The insulated design makes it appropriate for installations where wire protection at the conduit entry point is required. It is used wherever a short conduit section is needed to connect enclosures, panels, or junction boxes via threaded fittings.

Compatibility

Designed as an OEM-style replacement fitting for 4-inch trade size rigid metal conduit and intermediate metal conduit (IMC) systems in non-hazardous locations.

Installation Notes

Installation is performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits and verify power is off before working on any conduit system or enclosure. Use appropriate pipe wrenches and thread sealant rated for electrical conduit fittings when making threaded connections. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.
