Thomas Betts 850 Conduit Nipple 3-1/2 in Malleable Iron Imc

Product Description

The THOMAS BETTS 850 is a malleable iron conduit nipple designed for use with rigid and intermediate metal conduit (IMC) systems. It features a threaded connection and a 3-1/2 inch trade size, making it suitable for standard metallic conduit installations in non-hazardous locations. The non-insulated design is consistent with typical metallic raceway fittings used throughout commercial and industrial electrical work. Licensed electricians and electrical contractors rely on this type of fitting to connect conduit runs at junction boxes, panels, and enclosures where a short, close-coupled section of conduit is required.

The THOMAS BETTS 850 is used in non-hazardous area applications where rigid metal conduit (RMC) or intermediate metal conduit (IMC) is the specified raceway type. Common installation scenarios include service entrances, panel connections, meter socket terminations, and conduit transitions at enclosures or pullboxes. It suits both new construction and retrofit work in residential, commercial, and light industrial environments where metallic conduit is required by code or specification.

Key Features

• 3-1/2 inch trade size fits standard RMC and IMC conduit systems
• Malleable iron construction provides durability and thread integrity under torque
• Threaded connection on both ends for secure, code-compliant conduit terminations
• Non-insulated design for standard metallic raceway applications
• Rated for non-hazardous area use

Compatibility

Designed as an OEM-style fitting for use with 3-1/2 inch trade size rigid metal conduit (RMC) and intermediate metal conduit (IMC) in non-hazardous location installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for metallic conduit systems. De-energize all circuits in the enclosure or panel before making conduit terminations. Use appropriate pipe wrenches or conduit tools when threading the nipple into fittings or knockouts, and avoid over-tightening, which can crack cast or threaded enclosure hubs. Verify that the conduit system is properly bonded and grounded per NEC Article 250.
