FAQs
UNF105 SA is a 1/2" copper-free aluminum UNF union with a female gender designed for rigid/IMC conduit. For hazardous locations, verify compatibility with Class I and II ratings, use appropriate protective hardware, and follow standard procedures for sealing and joining to minimize ignition risk. Ensure tools and torque are appropriate for aluminum fittings and that all connections are clean and free of debris before assembly.
UNF105 SA supports rigid/IMC conduit with a 1/2" trade size. The female connection is designed to mate with corresponding male fittings, providing a secure, code-compliant joint suitable for industrial installations and hazardous-location applications.
Yes. The UNF105 SA carries NEC/CEC standards and a hazardous-location rating (Class I, Division 1 and 2; Class II, Division 1 and 2; Class III) with area-classification suitability for hazardous/classified locations, making it appropriate for chemical plants, refineries, and other demanding environments.
The union is copper-free aluminum, 1/2" trade size, female, with dimensions of 1.63 in length, 1.5 in height, and 1.5 in width, and a weight of 0.13 lb. The UPC is 782274101828, and it fits rigid/IMC conduit assemblies commonly used in industrial facilities.
Copper-free aluminum reduces weight and corrosion potential, improving installation efficiency and lifecycle cost. It enables easier handling, faster field assembly, and lower maintenance in harsh environments, while maintaining mechanical strength and NEC/CEC compliance for hazardous locations.
