Eaton Specification Sheet - EYS716
Feature: Sealing position can be vertical or horizontal. Business Impact: This orientation flexibility reduces the need for multiple fittings and allows a single part to cover diverse installation geometries, cutting inventory and simplifying procurement. Application: Ideal for compact panels, outdoor enclosures, and lines where conduit routing changes between vertical and horizontal runs, such as on process skids and offshore platforms. Feature: Body material is ductile iron or Feraloy iron alloy. Business Impact: Provides high mechanical strength and resistance to impact, corrosion, and thermal cycling, lowering maintenance costs and extending service life in demanding environments. Application: Suitable for seismic-heavy installations, vibration-prone equipment rooms, and locations subject to chemical exposure in refineries and chemical plants. Feature: Trade size 2-1/2 inch with male and female configuration. Business Impact: Ensures compatibility with standard conduit systems and secure mating to minimize leakage paths, reducing ingress and arcing risk. Application: Works with common 2-1/2 inch conduit runs in power distribution, motor control centers, and hazardous-area panels across manufacturing facilities. Feature: Group B rating and NEC/CEC compliance. Business Impact: Provides industry-accepted explosion protection and regulatory alignment, facilitating project approvals and documentation. Application: Enables safe installations in Class I, Division 1 and Division 2, Class II, and Class III environments found in oil/gas, mining, and chemical processing facilities. Feature: Area classification Hazardous/Classified Locations; installation versatility. Business Impact: Supports cross-industry use with reduced risk of downtime due to ingress. Application: Suitable for Class I/II/III environments across multiple facilities. Feature: Availability of CAD drawings, catalog pages, and installation resources. Business Impact: Accelerates design, procurement, and field work by referencing the 3D CAD package, catalog page, and IF 287 installation sheet. Application: Streamlines project workflows for engineering teams and procurement groups.

FAQs
The EYS716 is designed for explosion-proof conduit sealing in hazardous/classified locations, with vertical or horizontal sealing, 2-1/2 inch trade size, and a male/female configuration in ductile iron or Feraloy iron alloy. It supports NEC/CEC standards and ratings for Class I, Div 1 and 2, Class II Div 1 and 2, and Class III, enabling reliable sealing in oil, gas, chemical, and mining environments.
The fitting provides sealing in both vertical and horizontal orientations, leveraging a rugged ductile iron or Feraloy body and a male-female interface to minimize ingress paths. Its Group B rating and NEC/CEC compliance ensure dependable performance under vibration, temperature cycling, and dust exposure typical of hazardous-area installations.
Industries such as oil and gas, chemical processing, mining, and energy facilities benefit from the EYS716 due to its large 2-1/2 inch conduit capacity, robust material, and explosion-protection ratings. It supports safe, code-compliant conduit sealing across harsh environments where exposure to dust, moisture, and corrosive agents is common.
The EYS716 aligns with NEC/CEC standards and carries NEC hazardous ratings including Class I Division 1 and Division 2, Class II Division 1 and 2, and Class III. Area classification is Hazardous/Classified Locations, ensuring compliance for cross-border deployments in North American facilities.
Constructed from ductile iron or Feraloy alloy, the EYS716 delivers rugged reliability that reduces maintenance frequency. Its standard 2-1/2 inch size, durable sealing, and compatibility with common conduit systems simplify replacement and installation, yielding lower downtime and a favorable total cost of ownership in harsh industrial environments.
