Eaton Crouse-Hinds EYS16 conduit sealing fitting - Group B rated
Part Number: EYS16
Quick Summary
Eaton Crouse-Hinds EYS conduit sealing fitting seals hazardous-location conduits for reliable, field-installable protection. Unsealed penetrations invite moisture, dust, and corrosive vapors that cause equipment downtime and accelerated wear. This model aligns with NEC/CEC standards and UL certifications for hazardous environments, including area classifications for Class I Division 1 and Division 2 locations, with a Group B rating. Designed to simplify compliance and installation, it supports vertical-sealing assemblies and 1/2-inch trade size fittings to improve wiring integrity and maintenance uptime. Manufactured for feraloy iron alloy or ductile iron, the EYS16 provides robust protection in demanding industrial settings.

FAQs
The EYS16 is designed for 1/2 inch trade-size conduits and features male and female configurations to maximize compatibility with the Eaton Crouse-Hinds EYS/EZS sealing family. Its vertical-sealing design simplifies alignment during installation, reducing the risk of misfit seals and leaks. This compatibility supports streamlined spares management and faster panel buildouts in hazardous-location installations.
EYS16 is rated for Hazardous/Classified Locations and complies with NEC and CEC standards. It carries UL certifications for use in hazardous environments and supports classification of Class I, Division 1 and Division 2, as well as Class II and Class III locations. This certification suite ensures code compliance for a wide range of industrial, mining, and chemical processing facilities.
Yes. The EYS16 is designed for Class I Division 1 and related hazardous-location applications. Its Group B rating and robust feraloy/ductile iron construction provide the containment and durability required in high-risk environments. When selecting for Division 2 or Class II locations, confirm compatibility with the specific installation and enclosure requirements in the project specs.
Key installation considerations include using the vertical sealing orientation to optimize drainage and seal integrity, confirming 1/2 inch trade-size compatibility with existing conduit runs, and leveraging the EYS/EZS family for consistent sealing interfaces. Availability of installation sheets (IF 287) and a dedicated 3D drawing package facilitates accurate field mounting and faster commissioning.
The EYS16 reduces maintenance costs by minimizing ingress-related equipment wear and corrosion in hazardous locations. Its durable feraloy/ductile iron construction and certified compliance lower retrofit risks and downtime. While exact ROI depends on application, benefits include longer service intervals, fewer seal replacements, and safer operations in Class I/II processes and offshore facilities.
