Thomas Betts HO221 Conduit Nipple 1/2 in Rigid Imc Zinc

Product Description

The THOMAS BETTS HO221 is a non-insulated conduit nipple designed for use with rigid metal conduit and intermediate metal conduit (IMC) systems. Constructed from die cast zinc, this fitting provides a threaded connection for joining conduit sections or connecting conduit to enclosures, junction boxes, and panel knockouts. The 1/2 inch trade size fits standard 1/2 inch conduit runs. Licensed electricians and electrical contractors install this type of fitting during rough-in and final trim work in commercial and residential electrical installations. Its non-insulated, threaded design meets standard conduit assembly practice for non-hazardous locations.

The HO221 is suited for non-hazardous area electrical installations where rigid conduit or IMC is the specified raceway system. Common applications include branch circuit wiring, panel connections, and conduit-to-box transitions in light commercial, residential, and industrial settings outside classified hazardous locations. The threaded interface ensures a secure mechanical connection consistent with standard electrical raceway practice.

Key Features

• 1/2 inch trade size fits standard rigid and IMC conduit systems

Compatibility

Designed as an OEM-style fitting for 1/2 inch trade size rigid metal conduit and intermediate metal conduit (IMC) raceway systems in non-hazardous locations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits and disconnect power before working on any conduit system or enclosure. Use appropriate conduit wrenches or pliers to thread the nipple securely into fittings or knockouts without over-stressing the die cast body. Verify that all threaded connections are fully engaged and that the completed assembly meets local inspection requirements.
