Eaton Crouse-Hinds EYSR4 Retrofit Sealing Fitting - Hazardous
Part Number: EYSR4
Quick Summary
Eaton Crouse-Hinds EYSR4 retrofit sealing fitting is a rugged conduit sealing solution for hazardous locations. Retrofits in tight spaces or aging panels often struggle with ingress sealing and code compliance, driving maintenance costs and downtime. Certified to NEC/CEC standards with Class I, Division 2 (and Class II, Division 2) ratings and Hazardous/Classified Locations compliance, this device provides proven protection where safety matters most. The design uses Feraloy iron alloy for durability in harsh environments, and its 1-1/4 inch trade size fits common conduit systems. This combination translates into reduced downtime, lower replacement cycles, and a scalable path to compliant, efficient electrical installations. In addition, it aligns with industrial conduit sealing practices and broader safety expectations for modern manufacturing environments.
