Eaton Specification Sheet - EYS41
Feature → Business Impact → Application: The EYS41 uses a female sealing interface in Feraloy iron alloy and/or ductile iron, delivering high mechanical strength and resistance to harsh environments. This translates to lower maintenance costs and reduced risk of ingress-related failures in mining and refinery settings, where downtime is costly and equipment sits near aggressive chemicals and dust. Application: Ideal for vertical or horizontal sealing positions on 1-1/4" conduits in Hazardous/Classified Locations, including oil & gas platforms and chemical plants, where quick seal integrity is essential. Feature → Business Impact → Application: Group B rated construction provides reliable performance across temperature and vibration, supporting longer service intervals and predictable lifecycle costs. Application: Suitable for heavy industrial cabinets and outdoor enclosures exposed to temperature shifts and corrosive atmospheres. Feature → Business Impact → Application: NEC/CEC compliance and recognized area classification simplify procurement and installation, reducing project risk and speeding commissioning. Application: Integrates with standard Eaton Crouse-Hinds conduiting schemes, easing spares management and field troubleshooting. Feature → Business Impact → Application: Vertical or horizontal sealing capability offers installation flexibility, saving time during panel builds and field retrofit work. Application: Use in cramped spaces or on pre-assembled conduit runs where orientation flexibility improves fitment and reduces labor. Feature → Business Impact → Application: 1-1/4" trade size ensures compatibility with common conduit systems, enabling straightforward substitutions and upgrades. Application: Replaces older seals without changing surrounding hardware, improving retrofit efficiency. Feature → Business Impact → Application: 3D CAD drawing and installation manuals (from catalogues and IF 287 instructions) support precise planning and error-free assembly. Application: Design and verify sealing fittings in early project stages to minimize on-site risk and rework.

FAQs
The EYS41 is designed for vertical or horizontal sealing of 1-1/4" conduits in Hazardous/Classified Locations, with a female connection and Group B rating. When installing, verify the area classification, ensure compatible conduitogistics, and follow IF 287 instructions for sealing procedures. Proper torque and sealant use help maintain ingress protection and long-term reliability in tough environments such as petrochemical facilities.
Yes. The EYS41 supports both vertical and horizontal sealing positions, offering installation flexibility to accommodate tight spaces or complex conduit runs. This versatility reduces field fabrication, speeds up assembly, and allows you to maintain seal integrity regardless of orientation in equipment rooms, outdoor enclosures, or offshore substations.
The EYS41 complies with NEC/CEC standards and is rated for Hazardous/Classified Locations. It is designed to support Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III environments, aligning with safety and regulatory requirements for industrial electrical installations and helping ensure compliance during audits.
The seal uses Feraloy iron alloy and/or ductile iron for enhanced mechanical strength and corrosion resistance, paired with a Group B rating for hazardous locations. This combination provides robust protection against ingress in demanding environments like refineries and chemical plants, reducing maintenance frequency and extending equipment life while maintaining seal integrity under vibration and temperature variation.
The EYS41 matches a 1-1/4" trade size conduit system and integrates with standard Eaton Crouse-Hinds fittings, easing compatibility and spares management. Its installation instructions and 3D CAD resources support precise planning, reducing field errors. Routine maintenance is simplified by a reliable seal design and clear compliance documentation, delivering lower lifecycle costs and faster maintenance cycles.
