Eaton EYS7 SA Conduit Sealing Fitting - Hazardous Locations
Part Number: EYS7 SA
Quick Summary
The Eaton EYS7 SA conduit sealing fitting protects electrical conduits in hazardous locations by delivering robust, leak-free sealing for demanding industrial environments. This ensures critical equipment remains protected from dust, moisture, and explosive atmospheres while maintenance shocks and vibrations are mitigated. Installers often face challenges achieving reliable sealing in tight spaces or with vertical and horizontal orientations, which can lead to costly reworks. The EYS7 SA carries NEC/CEC compliance and hazardous-location ratings that support Class I, II, and III environments across Division 1 and 2, providing confidence during audits. Its copper-free aluminum construction offers excellent corrosion resistance and a lighter installation footprint, while the 2-1/2 inch trade size streamlines spec-to-install workflows for project teams and OEMs.
