Killark GUML-1 IMC Union 1/2 in

This Killark GUML-1 IMC Union is a 90-degree conduit fitting designed for electrical installations requiring a secure connection between conduit and a box. It suits electricians and contractors working with Intermediate Metal Conduit in hazardous or standard locations. The threaded aluminium construction provides a reliable link for 1/2 in trade size runs.

Capacity and headroom

The union connects 1/2 in female NPT to 1/2 in male NPT threads, accommodating IMC and threaded RMC of the same trade size. Its overall length of 1 3/4 in and height of 3 in define the space it occupies within a conduit run. The aluminium body weighs 0.16 lb, adding minimal load to the assembly.

Build integration

The plain finish aluminium fitting threads directly into compatible conduit and box entries without additional adapters. Its 90-degree angle allows routing changes in tight corners while maintaining a grounded path. The hazardous-location rating supports use in classified areas where standard fittings are not permitted.

Questions about this item

Will the 90-degree union align with my existing 1/2 in IMC conduit runs?

The union is designed for 1/2 in trade size IMC and threaded RMC with female-to-male NPT threads, matching standard conduit dimensions.

How can I verify the union is seated correctly after installation?

The 90-degree bend should sit flush between the conduit and box with threads fully engaged, and the overall length measures 1 3/4 in when assembled.

Does the package include locknuts or gaskets for the hazardous-location ends?

The union is supplied as a single aluminum fitting with plain finish; locknuts, gaskets or sealing compounds must be purchased separately.
