Rigid Union for 3/4 in Conduit

The Appleton Century Crofts UNY75NR-A is a straight union designed to join rigid conduit to a box in hazardous locations. It suits electricians and maintenance teams who need a reliable transition between 3/4 in female and male NPT threads.

Sustained Performance in Hazardous Areas

The aluminum body with a plain finish resists corrosion in Class I, Division 1 and 2 environments covering Groups A, B, C, D and Class II, Division 1 and 2 Groups E, F, G as well as Class III. It maintains its thread integrity and grounding path under continuous vibration and thermal cycling where lesser fittings loosen.

Simple Threaded Installation

Installers tighten the 3/4 in FNPT and MNPT ends with standard wrenches; no special tools or compounds are required. The most common error is cross-threading the tapered NPT joints, which can compromise the hazardous-location seal and require complete replacement.

Questions about this item

Does the aluminum body of the UNY75NR-A run hot when conduit carries heavy loads all day?

The fitting is a passive aluminum union with no electrical load, so it does not generate heat during continuous operation.

What conduit and box threads must already be on site for this 3/4 in union to connect?

You need 3/4 in rigid conduit with male NPT ends and a box or fitting with a 3/4 in female NPT opening.

Will the Class I Division 1 rating on this union match the older hazardous-location boxes we already have?

Yes, the UNY75NR-A carries Class I Division 1 and 2, Groups A–D, and Class II Division 1 and 2, Groups E–G, matching legacy fittings with the same ratings.
