  • Connects 1/2 in and 3/4 in rigid conduit securely

Application fit

The Appleton UNF75-50NR rigid union joins 1/2 in and 3/4 in threaded conduit runs in hazardous locations. It suits electricians and maintenance crews who need a straight female-to-female connection rated for Class I, II and III environments.

Capacity and headroom

The fitting accepts vertical or horizontal rigid conduit at the two trade sizes listed. Its 1 1/2 in overall length and 1 15/32 in profile fit tight enclosures, while the electroplated steel body resists corrosion in the rated divisions and groups.

Interface limits

The connection relies on FNPT threads at each end, so sealing depends on proper thread engagement and compound. The hazardous-location rating covers the specified classes and groups only; it does not extend to unlisted atmospheres or conduit types.

Questions about this item

Will the 1/2 in and 3/4 in FNPT ends connect to my existing rigid conduit without adapters?

The union has 1/2 in FNPT on one side and 3/4 in FNPT on the other, so it joins those two trade sizes directly.

How can I verify the electroplated steel finish meets the Class I Division 1 hazardous-location rating after installation?

The fitting is marked UNF and rated for Class I Division 1 and 2 Groups A, B, C, D; Class II Division 1 and 2 Groups E, F, G; and Class III.

Does the package include any locknuts, bushings or thread sealant for the 1 1/2 in overall length union?

The union is supplied as a single threaded steel fitting; locknuts, bushings and sealant are sold separately.
