3/4 in IMC conduit union

The HUBBELL KILLARK GUML-2WW joins 3/4 in IMC or threaded RMC conduit to a box at a 90 degree angle. Its female to male NPT threads allow a secure connection in hazardous-location fittings. The aluminium body with a plain gray finish suits industrial and commercial electrical installations. Electricians and maintenance crews use it to change direction in rigid metal conduit runs.

Thermal noise and power profile

The aluminium construction dissipates heat from conductors without active cooling, so the fitting runs silently and draws no power. No moving parts or electronics mean there is no acoustic signature or electrical load to manage. The plain finish adds no insulating layer that would alter thermal performance. It simply provides a reliable mechanical and electrical path.

3/4 in trade size and 90 degree turn

The union fits 3/4 in trade size conduit and creates a 90 degree bend between a female threaded hub and a male threaded nipple. Overall length is 1 5/8 in with a 2 in by 2 in profile, and the part weighs .21 lb. Select this fitting only when the conduit system uses 3/4 in IMC or threaded RMC and a right-angle box connection is required.

Questions about this item

How do I install the 3/4 in FNPT x MNPT union without cross-threading the aluminium threads?

Start both threads by hand until they seat fully, then tighten with a strap wrench on the flats; aluminium strips easily if forced with pipe wrenches.

What maintenance or replacement will the aluminium union need later?

Inspect the plain finish annually for oxidation or galling; replace the union if threads show deformation or the 90-degree bend restricts wire pulling.

What limit appears first when the union runs at its 90-degree bend under sustained load?

The 0.21 lb aluminium body heats faster than steel, so thermal expansion at the threaded joint becomes the limiting factor during continuous operation.
