3/4 in Threaded Rigid Union

The Appleton Century Crofts UNF75 is a threaded rigid union designed to join two sections of 3/4 in conduit. It suits electricians and installers working on hazardous-location raceway systems where a secure, code-compliant connection is required.

Replaces worn or damaged conduit couplings

This union replaces a standard coupling when the conduit run must accommodate expansion, contraction or vibration without stressing the fittings. The jump is worth it when the installation demands a hazardous-location rating and a female-to-female threaded joint that maintains grounding continuity.

Limited to 3/4 in rigid conduit systems

The fitting only accepts 3/4 in rigid conduit with matching FNPT threads, so it cannot be used with EMT, flexible metal conduit or larger trade sizes. Its hazardous-location rating covers Class I, II and III divisions, but it does not extend to environments outside those classifications.

Questions about this item

What trade size conduit fits the UNF75 rigid union?

The UNF75 rigid union accepts 3/4 in trade size rigid conduit on both ends.

How do I install the UNF75 union without cross-threading the 3/4 in FNPT threads?

Start both conduit ends by hand into the female threads, then tighten with a strap wrench to avoid damaging the powder-coated finish.

When should I replace the electroplated steel union in a hazardous location?

Replace the union if the electroplated coating shows corrosion, the threads are damaged, or the hazardous location rating is compromised by physical damage.
