Eaton Specification Sheet - EYS26 SA
Vertical sealing orientation reduces misalignment during assembly, delivering a reliable seal where conduits enter enclosures from above or below. This design minimizes installation errors and helps maintain enclosure integrity in vibration-prone environments. The result is faster commissioning, lower leakage risk, and predictable performance in hazardous locations across oil, gas, chemical, or mining facilities. Male and female configurations provide flexible usage across field and control room installations, reducing the need for additional adapters or fittings. This compatibility simplifies stock management and allows a single part to serve multiple wiring schemes, cutting procurement complexity. When paired with the related EYS/EZS assortment, installers gain a consistent sealing interface across the system, boosting change-out efficiency. Copper-free aluminum construction delivers corrosion resistance and lighter handling compared with traditional copper-bearing alloys. The reduced weight aids overhead installations and lowers shipping costs, while aluminum's strength maintains a durable seal in harsh environments. This combination supports long-term reliability in outdoor, tropical, or chemically aggressive locations without compromising safety. Group B rating and NEC/CEC certifications place the EYS26 SA within recognized code paths for hazardous installations. The device covers Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III environments, ensuring compliance in oil refineries, chemical processing plants, and other classified sites. By standardizing this compliance, maintenance teams avoid field-rework and stay audit-ready. With a 3/4-inch trade size, sealing performance aligns with common conduit systems, and its vertical sealing remains integral where space is constrained. The EYS26 SA integrates with Eaton's Crouse-Hinds EYS/EZS family, delivering a consistent interface across the network and simplifying stocking. Installers gain faster assembly, fewer seal-related call-backs, and improved long-term system reliability.

FAQs
EYS26 SA is designed for vertical sealing in hazardous locations per NEC/CEC with Class I, II, and III ratings. For installation, ensure the conduit enters the enclosure vertically, use compatible EYS/EZS fittings, and follow IF 287 instructions for proper sealing. Verify the environment matches Group B rating requirements and conduct a post-install seal integrity check to maintain compliance and reliability.
Key specs include 3/4-inch trade size, vertical-only sealing, copper-free aluminum construction, and both male and female configurations. It carries Group B hazardous-location ratings and NEC/CEC compliance, suitable for Class I, II, and III locations. The unit weighs 0.52 lb with overall dimensions around 1.5 in (W) x 3.75 in (H) x 1.5 in (D).
Yes. The EYS26 SA is rated for hazardous locations, including Class I, Division 1 and 2, under NEC/CEC standards. Its Group B rating and copper-free aluminum construction are tailored for explosive atmospheres typical in oil and gas processing and related industrial sectors, providing compliant conduit sealing for critical safety requirements.
EYS26 SA carries NEC/CEC compliance and Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III hazardous-location ratings. These certifications indicate suitability for use in explosive atmospheres, support safe installation practices, and facilitate regulatory audits across North American and global facilities where hazardous-location equipment is required.
By delivering a versatile, vertical-sealing solution with both male and female ends, 3/4-inch trade size, and copper-free aluminum, the EYS26 SA reduces need for adapters, minimizes rework, and speeds commissioning. Its Group B rating accelerates compliance processes, lowers maintenance risk, and improves long-term reliability in harsh environments, contributing to lower lifecycle costs.
