Eaton Specification Sheet - EYD66 SA
Copper-free aluminum construction delivers excellent corrosion resistance in hostile environments, extending service life and reducing maintenance in chemical plants, oil and gas facilities, and mining operations. This explosionproof conduit sealing fitting supports long-term reliability in harsh atmospheres while keeping weight manageable for field installations. The vertical drain design provides efficient moisture management, preventing condensation buildup that can compromise seals and enclosure integrity, which translates to fewer service calls and reduced downtime during starts and shutdowns. With a 2 inch trade size and male–female configuration, it offers compatibility with standard conduit runs, simplifying inventory management and speeding up panel assembly and field joinery. NEC/CEC compliance and hazardous location ratings ensure regulatory alignment, insurance compatibility, and safer installations in zones requiring robust explosion-protection. The copper-free aluminum body also reduces galvanic corrosion risks when paired with other metals in mixed-material enclosures, a common scenario in multi-vendor control rooms. Designed for vertical installations, it supports predictable drainage and cleaner wiring routes, minimizing enclosure dust ingress and easing future maintenance.

FAQs
Installation starts with confirming the 2 inch trade size and ensuring both male and female ends are clean and aligned. Mount the fitting in the vertical orientation, connect to the conduit runs, and tighten with approved fittings to maintain the drain path. Consult IF 287 guidance for conduit sealing and verify the drain is clear to promote moisture escape. Use the correct seals and hardware compatible with copper-free aluminum and hazardous area ratings to maintain explosion protection and enclosure integrity.
EYD66 SA carries NEC/CEC compliance and Hazardous/ Classified Locations ratings, including Class I Divisions 1 and 2, Class II Divisions 1 and 2, and Class III. These ratings confirm suitability for hazardous locations and explosion-protected conduit systems, ensuring regulatory alignment, safer installations, and potential insurance considerations in oil & gas, chemical processing, and other high-risk industries.
Yes. The EYD66 SA is designed for hazardous locations with explosionproof requirements, offering copper-free aluminum construction and a drain to manage moisture. Its 2" size and male/female configuration enable reliable, compliant conduit sealing in oil and gas and chemical processing environments, reducing maintenance needs and supporting safer, ongoing operations in corrosive atmospheres.
The EYD66 SA combines a copper-free aluminum body with a drain feature and vertical sealing orientation, all in a 2" trade-size package. This enables durable corrosion resistance, moisture management, and straightforward vertical installation in hazardous environments, while maintaining compatibility with conventional conduit systems and meeting NEC/CEC safety standards for Class I/II/III locations.
The copper-free aluminum construction resists corrosion in harsh environments, extending service life and reducing maintenance frequency. The drain minimizes moisture-related issues, lowering the risk of enclosure corrosion and electrical faults. Overall, this leads to lower downtime, predictable lifecycle costs, and enhanced reliability for critical automation and control systems operating in hazardous facilities.
