Conduit Union for Hazardous Locations

The Killark GUML-1MWW IMC union connects rigid metal conduit to a box at a 90-degree angle in hazardous areas. It is built for electricians and facility maintenance teams who need a secure, code-compliant transition between 1/2 inch conduit and an enclosure.

Threaded Installation with Standard Tools

The fitting uses 1/2 inch FNPT by MNPT threads for a direct screw-on connection. No special tooling is required beyond standard pipe wrenches. Care must be taken to start threads squarely to avoid cross-threading the electroplated steel surfaces.

Rated for 1/2 Inch IMC and RMC Systems

This union accommodates 1/2 inch trade size Intermediate Metal Conduit and Rigid Metal Conduit. The 1 3/4 inch overall length and 0.45 lb weight provide a compact profile for tight bends. It is not suited for larger trade sizes or non-threaded conduit types.

Questions about this item

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

Verify the 90-degree bend aligns the conduit run with the box entry and that both the female and male NPT threads are fully engaged without cross-threading.

What comes with the GUML-1MWW union and what must I supply?

The electroplated steel union is supplied complete; you must provide 1/2 in IMC or threaded RMC conduit, a matching box, and appropriate thread sealant.

Which version of this union fits my 1/2 in IMC system?

The GUML-1MWW is the single 1/2 in trade-size model with FNPT x MNPT ends, so it is the correct choice for 1/2 in IMC or threaded RMC installations.
