Hubbell GUF1 Explosion Proof Female Union Conduit

Product Description

The HUBBELL GUF1 is an explosion-proof female-to-female union fitting designed for use in hazardous location conduit systems. It connects two sections of rigid conduit or attaches conduit to junction boxes, fittings, and other electrical devices without requiring the conduit to be turned or removed during installation or service. Licensed electricians and industrial maintenance technicians install this fitting where NEC Article 500 hazardous location requirements apply. The female-to-female configuration simplifies equipment removal in tight or fixed conduit runs.

This union is suited for industrial and commercial hazardous location wiring installations where conduit systems must remain intact during equipment changeouts or maintenance. Common applications include petrochemical facilities, grain handling operations, wastewater treatment plants, and other classified locations requiring explosion-proof raceway assemblies. The fitting accommodates scenarios where rotating or dismantling the conduit is not practical.
