Eaton Specification Sheet - EYDX3 SA
The EYDX3 SA employs an expanded fill sealing design with a drain, which prevents water and condensate from entering the connection. This reduces maintenance cycles and unplanned downtime, delivering measurable uptime improvements in chemical processing, oil & gas, and refining environments. The copper-free aluminum body lightens handling during installation and resists corrosion in harsh environments, lowering labor costs and long-term component wear. With a 1" trade size and female gender, it ensures straightforward integration into standard conduit runs and simplifies inventory management for maintenance teams. Compliance is reinforced by NEC/CEC standards and UL hazardous-location certifications for Class I, II, and III locations, helping projects meet regulatory requirements with confidence. The vertical sealing position streamlines routing in constrained spaces, while compatibility with EYDX/EYSX fittings supports reliable retrofits and shrinks total installed cost. Field technicians also benefit from installation instructions and spec sheets that guide correct mounting and drainage.
