Conduit Union for Hazardous Areas

This 3/4-inch female union joins two rigid conduit runs in a straight line. The aluminum body carries Class I, Division 1 and 2 ratings for Groups A through D, plus Class II and Class III coverage. Plain finish resists corrosion in demanding industrial environments. Overall length measures 1 1/2 inches with a 1 15/32-inch square profile.

Indoor or Non-Hazardous Installations

Installers working in ordinary locations without explosive atmospheres do not need this rated fitting. Buyers who require a male-threaded connection or a different trade size must select another part. This union only accepts 3/4-inch FNPT ends on both sides.

3/4-Inch FNPT Female Threads

The defining specification is the dual 3/4-inch FNPT female thread pattern. Both conduit ends must match this thread form and trade size for a compliant seal. Mismatched threads or conduit diameters will prevent proper engagement in hazardous-area systems.

Questions about this item

Do I need 3/4 in rigid conduit with FNPT threads to connect this union?

Yes. The UNF75NR-A is a straight union with 3/4 in FNPT x 3/4 in FNPT ends, designed for vertical or horizontal rigid conduit of the same trade size.

Can this aluminum union join older steel conduit already in place?

It fits 3/4 in rigid conduit with FNPT threads regardless of age, but dissimilar metals in hazardous areas should follow local code.

How do I confirm the union is rated for my hazardous location after installation?

Check the body markings for Class I Div 1/2 Groups A-D, Class II Div 1/2 Groups E-G, and Class III ratings.
