Eaton EYDX7 SA Expanded Fill Sealing Fitting - Hazardous
Part Number: EYDX7 SA
Quick Summary
EYDX7 SA expanded fill sealing fitting seals conduit in hazardous locations with a drain, enabling reliable protection for industrial wiring. In the field, moisture ingress and corrosion can compromise enclosures and extend commissioning time; this fitting provides a robust seal and built‑in drainage to mitigate that risk. It carries NEC/CEC compliance and is rated for Class I, Division 1 and 2, Class II, Division 1 and 2, plus Class III hazardous locations, with Canadian certification available. Copper‑free aluminum construction lowers weight while delivering corrosion resistance in harsh environments. The vertical‑only sealing orientation simplifies installation in vertical runs and reduces field misalignment, delivering faster, more reliable installations and long‑term lifecycle value.

Drain-enabled expanded fill sealing provides a robust moisture barrier for hazardous-area conduits. This reduces maintenance cycles and corrosion-related downtime, delivering higher uptime and lower lifecycle costs. It’s ideal for vertical runs in chemical plants, refineries, and offshore facilities where drainage is a must. Copper-free aluminum construction provides corrosion resistance while keeping the weight manageable. This reduces handling effort, minimizes structural support requirements, and improves freight efficiency on large projects. It’s well-suited for harsh environments like chemical plants, mining, and offshore platforms. Vertical-only sealing position simplifies alignment and reduces the risk of incorrect orientation during field installs. It supports faster commissioning and fewer field reworks, especially in tight conduit runs where space is limited. This makes retrofits easier and reduces the chance of incorrect orientation during field assembly. Trade size 2-1/2 inches with a 4.75 by 4.75 inch footprint ensures compatibility with standard conduit systems and enclosure openings. NEC/CEC compliance and hazard-location ratings provide regulatory confidence across North American projects, with Canadian certification available to support cross-border approvals. The drain-enabled design helps manage condensate and moisture, lowering corrosion risk and maintenance frequency, while the rugged construction provides long service life in demanding plants.

FAQs
Plan for vertical runs to leverage the sealing orientation and ensure the drain is positioned to collect condensate away from electrical contacts. Verify compatibility with 2-1/2 inch conduit openings and enclosure cutouts; use appropriate seals and gaskets per installation sheets. Follow IF 288 guidelines for EYDX fittings to ensure proper torque, mounting, and connection to conduits.
EYDX7 SA is designed for hazardous locations under NEC/CEC. It is rated for Class I, Division 1 and Division 2, Class II, Division 1 and 2, and Class III. The product is manufactured in copper-free aluminum and supports NEC/CEC compliance, with Canadian certification available. This combination supports compliant approvals in North American plants and cross-border projects.
Yes, EYDX7 SA features a vertical-only sealing position, simplifying alignment in upright conduit runs and reducing misassembly during installation. It supports standard 2-1/2 inch conduits and offers drain-enabled sealing to keep enclosures dry, improving commissioning times and uptime in hazardous environments. It also facilitates retrofits by reducing orientation errors during field assembly.
The copper-free aluminum construction offers excellent corrosion resistance, while the built-in drain minimizes moisture buildup inside enclosures. These features reduce maintenance frequency and corrosion-related downtime, lowering total cost of ownership over the life of the installation. The rugged seal design also supports longer service intervals in demanding hazardous-area facilities.
