Eaton EYD56 SA Conduit Sealing Fitting - Class I/II/III
Part Number: EYD56 SA
Quick Summary
The Eaton EYD56 SA conduit sealing fitting is designed to seal and drain conduit entries in hazardous locations. In harsh industrial environments, moisture ingress and contamination can compromise splices and accelerate corrosion if fittings lack drain capability. This model meets NEC/CEC requirements and is rated for Hazardous/Classified Locations, including Class I, Division 1 and Class II, Division 1 (and Class III per spec). Constructed from copper-free aluminum, it combines light weight with durability. Its vertical-only sealing and 1-1/2 in trade size fit standard conduit runs, while the male and female configuration simplifies field installation and reduces inventory complexity for maintenance crews.

Eaton Specification Sheet - EYD56 SA
Copper-free aluminum construction reduces weight and total life-cycle cost, easing handling during installation and minimizing material waste on site. The corrosion-resistant body stands up to humid plants, offshore platforms, and wet process areas, helping maintenance teams extend service intervals and lower replacement expenses. With a 1-1/2 inch trade size and a male-and-female design, the unit delivers flexible field assembly and faster connections across standard conduit runs. Vertical sealing position simplifies orientation in enclosures and reduces the risk of improper drainage, while the drain feature actively channels condensate away from splices. Rated for Hazardous/Classified Locations under NEC/CEC standards, including Class I Division 1, Class II Division 1, and Class III, the fitting supports compliant installations in chemical, petroleum, mining, and other harsh environments. This reliability translates to improved safety margins and faster project commissioning. Built to withstand installation demands, the EYD56 SA pairs with typical conduit seals and spare parts in Eaton's Crouse-Hinds range, enabling streamlined inventory management and compatibility with existing conduit systems.

FAQs
The EYD56 SA is designed for Hazardous/Classified Locations under NEC/CEC, including Class I Division 1 and Division 2, Class II Division 1 and 2, and Class III. It is well-suited for chemical plants, refineries, mining, and other facilities where explosive atmospheres or dust hazards require robust sealing and drainage in conduit installations.
Yes. The EYD56 SA features a drain to channel condensate away from splices, reducing moisture-related corrosion and prolonging the life of sealed conduit connections in challenging environments such as wet process areas and outdoor installations.
The fitting is designed for a 1-1/2 in trade size with male and female configurations, offering flexible field assembly. It uses a vertical sealing position, which simplifies orientation in enclosures and helps ensure proper drainage in vertical runs.
This product carries NEC/CEC standards for hazardous locations and area classifications, including Class I, Division 1/2 and Class II, Division 1/2, with Class III ratings. UL certification for use in hazardous locations is available in Eaton’s certification listings, supporting regulatory compliance and project acceptance.
The copper-free aluminum construction lowers weight and reduces material costs, while corrosion resistance extends service intervals. The drain feature minimizes condensate-related faults, reducing maintenance time and downtime. Overall, this leads to faster installations, fewer field calls, and improved lifecycle cost in harsh environments.
