Eaton EYS316 conduit sealing fitting - Group B rated
Part Number: EYS316
Quick Summary
Eaton EYS316 conduit sealing is a rugged sealing fitting for hazardous-location conduit installations. In field deployments, mismatched seals or improper orientation can lead to moisture ingress, equipment downtime, and non-compliance with safety standards. This model carries NEC/CEC credentials and hazardous-location ratings—Class I, Division 1 and 2, Class II, Division 1 and 2, Class III—with a Group B rating, and supports vertical or horizontal sealing. For engineering teams and procurement, the reliability of a single 1" fitting simplifies inventory while ensuring regulatory alignment. The combination of ferrous alloy construction, field-appropriate installation, and compatible mounting options reduces maintenance costs and minimizes commissioning risk in demanding environments. UL Canadian certification further reinforces cross-border compliance for global projects.

FAQs
Yes. EYS316 is a 1" trade-size conduit sealing fitting designed to mate with standard 1" conduit components. It provides both male and female configurations and supports vertical or horizontal sealing, enabling straightforward integration into existing conduit runs and control-panel assemblies.
The EYS316 carries NEC/CEC compliance and Hazardous/Classified Locations ratings, including Class I Division 1 and 2, Class II Division 1 and 2, and Class III. It is Group B rated and also has documentation supporting Canadian certification, which supports cross-border compliance in multi-site plants.
Ideal for explosion-protected installations in oil, gas, chemical processing, mining, and other hazardous environments. Its vertical or horizontal sealing and robust ferrous alloy construction make it well-suited for outdoor enclosures, heavy-duty cabinets, and areas with harsh chemical exposure or vibration.
Install with the appropriate 1" conduit, ensuring matching male/female interfaces and proper sealing orientation (vertical or horizontal). Follow standard installation instructions (IF 287) and consult the Eaton specification sheet for torque guidance, mounting hardware compatibility, and safety considerations to ensure a compliant, sealed termination.
The hardened ferrous construction, reliable sealing, and compatibility with standard 1" conduit reduce maintenance cycles and replacement costs. Group B rating and NEC/CEC compliance help prevent regulatory downtime, while vertical/horizontal sealing flexibility shortens installation time, delivering lower lifecycle labor costs and faster project ROI.
