Thomas Betts 605-TB Conduit Reducer 1-1/4 to 3/4 in Rigid Imc

Product Description

The THOMAS BETTS 605-TB is a threaded steel conduit reducer designed for use with rigid metal conduit and intermediate metal conduit (IMC) systems. It transitions from a 1-1/4 inch trade size conduit down to a 3/4 inch trade size, allowing electricians to reduce conduit runs at junction boxes, panels, or enclosures without adding adapters or extra fittings. The fitting is non-insulated and rated for non-hazardous area applications. Constructed from steel, it provides the mechanical strength required for standard commercial and residential electrical installations. Licensed electricians and conduit installers are the primary users of this fitting in rough-in and service work.

This reducer is suited for rigid metal conduit and IMC installations in commercial, industrial, and residential settings where a threaded connection is required between differing conduit trade sizes. It is appropriate for use in dry, damp, or non-hazardous environments where standard steel conduit fittings meet code requirements. The threaded interface ensures a secure, wrench-tight connection that meets standard installation practices for conduit systems. It is commonly installed at enclosure knockouts, pull boxes, and conduit body entries where a size transition is needed.

Key Features

• Reduces from 1-1/4 inch to 3/4 inch trade size for conduit transitions
• Threaded connection type for secure, wrench-tight installation
• Steel construction provides durability in standard conduit systems
• Compatible with both rigid metal conduit and IMC conduit types
• Non-insulated fitting for non-hazardous area use

Compatibility

Designed as an OEM-style replacement and standard-fit reducer for rigid metal conduit and intermediate metal conduit (IMC) systems requiring a threaded 1-1/4 inch to 3/4 inch trade size transition in non-hazardous locations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify the absence of voltage before beginning any conduit work at panels or enclosures. Apply appropriate thread sealant or conduit wrench as needed to achieve a secure, watertight-equivalent mechanical connection. Do not use this fitting in classified hazardous locations where explosion-proof or sealing fittings are required.
