Eaton Crouse-Hinds EYS9 Conduit Sealing Fitting - NEC/CEC
Part Number: EYS9
Quick Summary
Eaton Crouse-Hinds EYS9 conduit sealing fitting secures and seals conduit in hazardous locations for industrial controls. Difficulties sealing penetrations in such environments often lead to ingress, corrosion, and costly downtime. It carries NEC/CEC compliance with Class I–III ratings across Division 1–2, supporting safe operation in demanding environments. Secondary benefits include rugged ductile iron construction and vertical or horizontal sealing for flexible installation and long service life. This aligns with maintenance strategies to reduce total cost of ownership. Field technicians appreciate clear orientation options for vertical or horizontal sealing and straightforward installation. By meeting industry standards, the EYS9 supports faster project turnover and safer facilities.

Eaton Specification Sheet - EYS9
Rugged construction with ductile iron and Feraloy iron alloy provides extended service life in harsh environments, reducing maintenance labor and replacement costs while enhancing safety in hazardous locations. Business impact: lower total cost of ownership and fewer unplanned outages; Application: refinery, chemical plant, and mining environments where corrosion resistance and durability matter. The 3-1/2" trade size aligns with common conduit runs, accelerating design-in and installation without custom adapters. How this helps you: faster commissioning, fewer field modifications, and improved uptime metrics for critical electrical feeds. Compatibility with standard conduit fittings simplifies procurement and reduces stocking diversity, supporting lean maintenance programs. Industry context: explosionproof and sealed fittings like this are integral to compliant, safe installations in regulated facilities.

FAQs
EYS9 is a 3-1/2" trade size female conduit sealing fitting designed for vertical or horizontal sealing. It fits standard conduit assemblies used in Class I, II, and III hazardous locations and adheres to NEC/CEC requirements, with mounting flexibility and straightforward orientation to minimize field rework and installation time.
EYS9 carries NEC/CEC compliance with hazardous-location ratings across Class I, Division 1 and 2, Class II Division 1 and 2, and Class III. It’s designed for Hazardous/Classified Locations and supports area classifications that require robust sealing in explosive environments, helping meet regulatory and project-specific safety mandates.
Installers should note the vertical or horizontal sealing capability and the female configuration, which facilitates field assembly with standard conduit runs. Refer to IF 287 - Conduit Sealing for installation guidance, and verify compatibility with a 3-1/2" trade size and the unit’s dimensions (7.25 in length, 13.38 in height, 6 in width) to ensure proper clearance and access.
Yes. EYS9 is designed for hazardous locations with NEC/CEC certification, offering Class I, II, and III ratings across Division 1 and 2. Its sealed, corrosion-resistant construction makes it appropriate for explosionproof applications, enhancing safety and regulatory compliance in oil, gas, and chemical processing facilities.
The combination of ductile iron (or Feraloy iron alloy) and sealed vertical/horizontal operation delivers long service life with reduced maintenance cycles and lower ingress-related risk. This translates to fewer replacements, lower downtime, and faster project turnover, delivering a favorable return on investment in hazardous-location installations.
