Eaton Specification Sheet - EYSX2 SA
Copper-free aluminum provides robust corrosion resistance without the weight penalties of stainless steel, extending service life in aggressive industrial environments such as offshore platforms, chemical plants, and refineries. This material choice minimizes maintenance cycles and replacement costs while maintaining mechanical strength crucial for conduit fittings in harsh service. Users gain predictable performance under salt spray, humidity, and thermal cycling. With a 3/4 inch trade size and female connection, the EYSX2 SA aligns with standard conduit systems and simplifies field terminations. Its sealing position can be vertical or horizontal, easing routing in crowded panels and tight installations. The design reduces rework by accommodating common installation geometries without special adapters. Expanded fill sealing increases fill capacity while maintaining seal integrity, helping avoid under- or over-filled conduits. This results in quicker installations and fewer seal failures in hazardous locations, delivering measurable productivity gains. The approach is well-suited for high-density electrical layouts and retrofits where space is at a premium. NEC/CEC compliance and UL hazardous-location listings underpin regulatory acceptance across North America, covering Class I, II, and III service with Divisions 1 and 2. Certification visibility supports project approvals, audits, and maintenance planning. End users also benefit from documented installation instructions and datasheets that streamline commissioning. Compact dimensions (1.75 in length) and a light 0.73 lb weight simplify handling, mounting, and inventory management on busy sites. The unit ships with official Eaton literature, including IF 288 instruction sheets and the EYSX2 SA datasheet, reducing guesswork during startup. Field technicians appreciate consistent performance and predictable torque when securing fittings. Overall, the EYSX2 SA delivers safer, faster, and more compliant conduit sealing for hazardous locations by pairing durable aluminum with proven sealing technology, backed by industry-standard certifications.

FAQs
For hazardous locations, ensure proper enclosure and conduit alignment before mounting. The EYSX2 SA is designed for vertical or horizontal sealing and uses a copper-free aluminum body, facilitating easier field termination. Confirm NEC/CEC compliance and UL hazardous-location listings for Class I, II, and III environments, and follow Eaton's IF 288 instructions to minimize risk during commissioning.
EYSX2 SA is classified for Hazardous/Classified Locations with NEC/CEC standards and UL listings for Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III. This certification set supports regulatory acceptance, project approvals, and ongoing maintenance audits across North America, reducing compliance-related project risk.
Yes, the EYSX2 SA is a 3/4 inch trade size female sealing fitting. It measures 1.75 in in length and width, stands 4.31 in tall, and weighs approximately 0.73 lb, making it suitable for compact, space-constrained installations while maintaining robust sealing performance.
This fitting excels in explosionproof conduit sealing for hazardous locations such as oil & gas facilities, chemical plants, and mining operations. Its expanded fill design, copper-free aluminum construction, and vertical/horizontal sealing capability enable reliable performance in challenging environments and aid in meeting stringent safety and regulatory requirements.
Expanded fill sealing provides higher fill capacity with solid sealing integrity, reducing rework and the likelihood of leaks in dense conduit runs. This translates to faster commissioning, lower maintenance costs, and longer service life in hazardous environments, contributing to a lower total cost of ownership over the life of the electrical installation.
