Eaton EYD66 Conduit Seal Fitting with Drain – Class I/II
Part Number: EYD66
Quick Summary
EYD66 Conduit Seal Fitting with Drain provides reliable, explosionproof sealing for electrical conduit in hazardous locations. Many installations struggle with leaks, drainage buildup, and corrosion when fittings aren’t rated for tough environments, leading to unplanned downtime. The design carries NEC/CEC compliance and NEC hazardous ratings for Class I and II, Divisions 1 and 2, plus coverage for Class III environments, ensuring safe operation under demanding conditions. Vertical-only sealing, feraloy iron alloy and ductile iron construction, and a 2" trade size deliver robust protection with predictable maintenance costs. This combination supports OEMs and facilities managers seeking compliant, long-life conduit sealing that reduces maintenance cycles and total cost of ownership.

Eaton Specification Sheet - EYD66
Drain-capable sealing is a core feature that prevents water ingress and condensation, reducing corrosion risk and extending the life of field-installed conduits. The business impact is lower maintenance costs and higher uptime in hazardous environments. It is ideal for vertical conduit runs in oil and gas, chemical processing, and power facilities where drainage and reliability are critical. By eliminating moisture ingress, it also helps protect internal connectors and seals from salt spray and washdowns. Rugged ductile iron with a feraloy iron alloy core delivers high mechanical strength and impact resistance. This translates to longer service intervals and safer operation in vibration-prone equipment rooms and outdoor installations. The vertical sealing orientation supports gravity drainage, keeping the interior dry even in heavy rain or humidity. The fitment is well-suited for entry points through rugged enclosures and process areas where metal fatigue is a concern. NEC/CEC compliance and explicit hazardous location ratings (Class I and II, Division 1 and 2, plus Class III) reduce regulatory burden and simplify procurement. The package aligns with explosionproof requirements that many facilities specify in procurement specs, enabling inspectors to pass installations without extensive deviations. By meeting multiple standards in one part, it accelerates approvals and reduces the need for multiple adapters in hazardous areas. Canadian certification adds a further layer of market confidence for North American projects. With a 2 inch trade size, male and female configuration, and vertical sealing position, EYD66 offers flexible integration with standard conduit systems. It simplifies inventory management and speeds installation, especially in tight spaces where a non-draining seal would complicate routing. The male and female compatibility reduces the number of field modifications required during retrofits, while the vertical seal minimizes misalignment during assembly. Documentation including IF 287 installation guidance and the Eaton datasheet supports correct orientation and torque, reducing commissioning errors. The combination of robust materials, proven drainage design, and formal installation instructions yields predictable performance and lower lifecycle costs. Field teams benefit from clear guidance, faster training, and fewer callbacks, driving overall project productivity in critical hazardous-area projects.

FAQs
EYD66 is designed with a drain-enabled sealing feature that prevents water ingress and moisture buildup inside the conduit fitting. This drainage capability protects internal seals from corrosion, reduces maintenance needs, and improves reliability in wet or washdown environments commonly found in chemical plants and offshore facilities.
The EYD66 carries NEC/CEC compliance and explicit hazardous location ratings, including Class I and II, Division 1 and 2, with coverage that extends to Class III environments. This ensures regulatory alignment for installations in hazardous locations and simplifies procurement and inspection processes.
Yes. The EYD66 is specifically configured for a 2 inch (2") trade size and vertical sealing position. It uses male and female connections in a ductile iron/feraloy alloy body, making it compatible with standard conduit runs and vertical penetrations in hazardous-area enclosures.
Installation guidance is available via Eaton documentation, including IF 287 - Conduit Sealing and the EYD66 datasheet. These resources provide orientation, torque recommendations, and step-by-step instructions to ensure proper sealing, orientation, and compliance during commissioning.
The EYD66 reduces maintenance and downtime by preventing moisture-related faults and corrosion, improving uptime in hazardous environments. Its certified compliance streamlines audits, lowers risk of non-compliant installations, and reduces lifecycle costs through fewer field modifications and longer service life.
