Eaton Crouse-Hinds EYD9 SA Sealing Fitting - Hazardous
Part Number: EYD9 SA
Quick Summary
EYD9 SA conduit sealing fitting with drain delivers robust sealing for hazardous-location electrical conduit runs. Engineers often struggle to keep moisture and contaminants out while meeting NEC/CEC requirements in harsh environments. This model carries NEC/CEC compliance with Hazardous/Classified Locations area classification and Class I, II, III ratings, plus Canadian certification options. Copper-free aluminum construction offers durable, corrosion-resistant performance, while the drain feature reduces moisture accumulation and simplifies drainage during operation. In practice, this enables reliable installation, reduces maintenance cycles, and lowers total cost of ownership by combining rugged material with proven sealing performance. Field teams appreciate the vertical sealing orientation and 3-1/2" trade size for straightforward integration into existing conduit systems.

FAQs
Yes. The EYD9 SA is a female conduit sealing fitting designed for 3-1/2" trade-size conduit and provides a vertical sealing configuration. Its copper-free aluminum body simplifies handling and installation, and its drain feature supports moisture management in hazardous environments. For best results, follow the IF 287 installation sheet and pair with standard conduit bodies to ensure a secure, compliant seal in the field.
The EYD9 SA carries NEC/CEC compliance and area classification for Hazardous/Classified Locations. It supports Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III ratings. Canadian certifications are available through UL, and the catalog materials provide validated installation data to help meet regulatory requirements in North American facilities.
This sealing fitting excels in hazardous-location environments such as chemical plants, oil/gas, mining, and other installations where moisture ingress can compromise conduit seals. The integrated drain helps expel condensate and liquids that may accumulate inside the fitting, improving long-term reliability and reducing corrosion-related failures in demanding service conditions.
NEC/CEC compliance ensures that the EYD9 SA meets essential safety and performance requirements for explosive and hazardous locations. When planning installations, verify Class I/II/III ratings and area classifications to determine suitability for your specific hazardous environment. The availability of Canadian certifications further supports cross-border projects and ensures consistent regulatory alignment.
Eaton provides full technical documentation, including the EYD9 SA specification sheet, IF 287 installation instructions, and the EYD/EZD catalog pages. Availability of CAD drawings, installation sheets, and a Canadian certification reference enhances project validation, procurement speed, and ongoing maintenance planning for explosion-proof conduit sealing fits.
