Eaton Specification Sheet - EYS56 SA
Copper-free aluminum construction reduces weight and corrosion risk, delivering easier handling and longer service life in outdoor or chemically aggressive plants. This translates to lower field fatigue during installation and reduced maintenance costs over the asset life. The 1-1/2 inch trade size with male and female configuration enables flexible mating with standard conduit fittings and simplifies spares management. In automation and process lines, this compatibility shortens install time and minimizes assembly errors. Vertical or horizontal sealing provides installation flexibility, letting technicians orient fittings to cabinet openings or conduit runs without compromising seal integrity. This capability supports compact layouts and safer wiring routes in crowded plant floors. Compliance with NEC/CEC and hazard-area ratings reduces regulatory risk and accelerates approval in projects subject to hazardous-location codes. Its Class I, Division 1/2, Class II, Division 1/2, and Class III ratings cover a wide range of industries from oil & gas to chemical processing. Canadian certification and UPC reference support cross-border procurement and traceability, while copper-free aluminum keeps weight down for easier handling during maintenance and retrofit work.

FAQs
The EYS56 SA supports a 1-1/2" trade size and is available in male and female configurations for flexible mating with standard conduit fittings. It is designed for vertical or horizontal sealing, enabling straightforward orientation during installation. For best results, follow the instruction sheet IF 287 and ensure proper torquing and seal seating to maintain hazardous-location integrity.
Its copper-free aluminum construction provides a lighter yet durable sealing solution, reducing field handling fatigue and improving corrosion resistance in harsh environments. The fitting’s explosionproof design and NEC/CEC compliance reduce regulatory risk, while the sealed interface minimizes ingress, protecting conductors and reducing maintenance cycles in Class I, Division 1/2 and Class II/Division 1/2 installations.
Yes. The EYS56 SA is designed to interface with standard Eaton Crouse-Hinds conduit sealing systems and is suitable for use alongside EYS and EZS series fittings. This compatibility simplifies spares inventories and supports scalable, modular installations across process lines and control cabinets.
The product carries NEC/CEC standards compliance with hazard-area ratings including Class I, Division 1 and Class II, Division 2 locations, as well as Canadian certification. This combination supports cross-border project deployment and meets common industrial regulatory requirements for hazardous locations.
By reducing ingress risk and weight, the EYS56 SA lowers maintenance effort and speeds up field installations, cutting downtime during commissioning and retrofit projects. The durable, corrosion-resistant copper-free aluminum improves long-term reliability in harsh environments, contributing to lower total cost of ownership in oil & gas, chemical processing, and other hazardous-location applications.
