Feature → Business Impact → Application: 1-1/2 inch trade size with both male and female connections simplifies mating and reduces installation time, cutting field labor in new builds and retrofit projects. This improves overall project efficiency and minimizes commissioning delays in hazardous environments where space and alignment matter. Feature → Feraloy iron alloy and ductile iron construction delivers exceptional durability and corrosion resistance in aggressive atmospheres, translating to longer service life and lower maintenance in chemical plants and refineries. Feature → Vertical or horizontal sealing orientation provides flexibility to accommodate equipment layouts and cabinet configurations, reducing retrofit costs and enabling easier retrofits in constrained installations. Feature → Group B rating and NEC/CEC compliance assure regulatory alignment and safer operation in Division 1 and Division 2 zones, decreasing risk of code violations and potential penalties. Feature → 1-1/2" sealing with male and female ends supports quick replacements and standardized spares, enabling better inventory control and faster repair cycles. Feature → Available installation resources such as IF 287 instructions, CAD drawings, and datasheets shorten design time and improve install quality, reducing on-site errors and rework. Measured outcomes include reduced downtime, improved safety margins, and predictable lifecycle costs in hazardous location projects.

FAQs
Yes. EYS516 is designed for 1-1/2" trade size conduits and supports both vertical and horizontal sealing. This dual-orientation capability simplifies layout planning, reduces the need for extra fittings, and accelerates the install in tight or awkward spaces typical of hazardous locations.
EYS516 carries NEC/CEC compliance and hazardous-location approvals, including Class I, Division 1 and Division 2, Class II Division 1 and Division 2, and Class III. These ratings ensure suitability for hazardous environments such as chemical processing, oil and gas, and mining applications, reducing regulatory risk and supporting safe electrical installations.
Yes. The EYS516 is rated for Class I, Division 1 and Division 2 locations, making it appropriate for chemical plants and other facilities with flammable or hazardous atmospheres. Its Group B rating further reinforces suitability for these demanding environments by meeting stringent industry standards.
Installation resources include IF 287 - Conduit Sealing instructions, a 3D CAD drawing package, a Crouse-Hinds catalog page, and a detailed specification sheet. These materials support correct sizing, orientation, material compatibility (Feraloy iron alloy or ductile iron), and proper sealing technique to minimize field errors.
EYS516 uses durable Feraloy iron alloy and/or ductile iron for rugged service life in harsh environments. Its sealed design minimizes ingress and corrosion, reducing maintenance cycles. Regular inspection per site procedures is recommended, and replacement should rely on standard 1-1/2" fittings to maintain certified hazardous-location compliance and system integrity.
