Appleton 1 in Rigid Union Conduit

This Appleton UNFL100 rigid union connects two sections of 1-inch threaded conduit in hazardous locations. It provides a secure female-to-female joint for vertical or horizontal runs. The fitting is built for Class I, Division 1 and 2 environments. It suits electrical contractors working in demanding industrial settings.

Powder-coated steel resists corrosion in harsh areas

The steel body carries an electroplated finish that withstands exposure to moisture and chemicals. It maintains structural integrity across Class I Groups A through D and Class II Groups E through G. The 4 3/4 inch overall length bridges conduit ends without adding excessive bulk. This durability supports long-term installation reliability.

Threaded ends simplify conduit assembly

Installation requires standard 1-inch FNPT threading tools for a tight seal. The female threads accept compatible rigid conduit directly without adapters. Misalignment during tightening can damage threads if forced. Proper torque ensures the hazardous-location rating remains effective.

Questions about this item

Does the UNFL100 union generate heat during continuous electrical service?

The steel union is a passive conduit fitting with no electrical components, so it does not generate heat during operation.

What conduit and tools are required to install this 1 in threaded union?

You need 1 in rigid conduit with matching female NPT threads, thread sealant rated for hazardous locations, and standard pipe wrenches for tightening.

Will the Class I Division 1 rating remain valid when connecting to older rigid conduit?

Yes, the UNFL100 is listed for Class I Division 1 Groups A–D and Class II Division 1 Groups E–G when mated with 1 in rigid conduit that meets the same hazardous-location standards.
