Thomas Betts H075-TB Conduit Hub 3/4 in Rigid Imc Zinc

Product Description

The THOMAS BETTS H075-TB is a 3/4-inch trade size conduit hub designed for use with rigid metal conduit and intermediate metal conduit (IMC) systems. Constructed from zinc, this hub features a threaded connection and partial insulation to protect conductors at the point of entry. It is rated for hazardous location and watertight applications, making it suitable for demanding industrial and commercial electrical installations. Licensed electricians and electrical contractors install this fitting where conduit enters enclosures, junction boxes, or panels requiring a secure, sealed termination point.

This conduit hub is used in commercial and industrial settings where rigid or IMC conduit must terminate at enclosures in wet, damp, or hazardous environments. Its watertight and hazardous location ratings make it appropriate for applications such as process plants, refineries, food service facilities, outdoor electrical enclosures, and other areas subject to moisture ingress or classified area requirements. The 3/4-inch trade size accommodates standard rigid and IMC conduit of that trade size without modification.

Key Features

• 3/4-inch trade size fits standard rigid metal conduit and IMC
• Zinc construction provides corrosion resistance in demanding environments
• Threaded connection ensures secure, reliable conduit termination
• Partially insulated interior protects wire insulation at enclosure entry
• Rated for hazardous location and watertight applications

Compatibility

Designed for use with 3/4-inch trade size rigid metal conduit and intermediate metal conduit (IMC) in threaded conduit installations requiring hazardous location or watertight rated fittings.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes, including requirements for hazardous location wiring methods. De-energize and lock out the enclosure before beginning any conduit work. Thread the hub fully onto the conduit and tighten securely to the enclosure knockout to maintain the watertight rating. Do not over-tighten in a way that damages the zinc body or insulating liner.
