Eaton Specification Sheet - EYS316 SA
Copper-free aluminum construction delivers corrosion resistance and lighter weight, reducing handling and installation time while preserving rugged durability in harsh environments. The Group B rating reinforces suitability for hazardous locations, helping you meet NEC/CEC compliance and risk reduction objectives in a single, compact fitting. Trade size is 1 inch and includes both male and female configurations, enabling flexible field assembly and streamlined splicing of conduit runs. This reduces parts variety and on-site labor, accelerating project timelines. Vertical or horizontal sealing position provides installation versatility when space constraints limit orientation. This flexibility simplifies retrofits and upgrades in industrial plants. NEC/CEC compliance and detailed hazardous-location ratings guarantee that the fitment is appropriate for Class I, II, and III environments, satisfying regulatory requirements and improving procurement confidence. UL certifications further validate safety and performance for North American use. Operational durability and cost-of-ownership benefits are achieved through copper-free aluminum, which resists corrosion and reduces weight. Shipping, mounting stress, and on-site handling are all improved, supported by installation resources such as IF 287 and the Eaton specifications.
