Eaton Crouse-Hinds EYD4 Conduit Sealing Fitting - Hazardous
Part Number: EYD4
Quick Summary
EYD4 conduit sealing fitting with drain provides explosionproof conduit sealing for hazardous locations in industrial plants. Maintenance teams often battle moisture ingress and corroded seals in harsh environments; a drain-equipped seal minimizes water buildup and downtime. This model carries NEC/CEC compliance and UL certifications for Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III, plus area classification for hazardous locations. Its 1-1/4" female connections and vertical-only orientation, combined with ductile iron or Feraloy iron alloy construction, deliver robust sealing in space-constrained installations while offering straightforward retrofit with standard fittings. The combination of materials and certifications translates to higher system reliability and lower lifecycle costs for process plants and refineries.

Eaton Specification Sheet - EYD4
Drainable sealing feature reduces moisture ingress and helps prevent corrosion, delivering measurable uptime improvements in challenging environments. By keeping water out of the conduit seal, facilities see fewer seal failures and less maintenance downtime. Material choice combines strength with resilience: ductile iron and Feraloy iron alloy provide robust mechanical protection against impact and corrosion in harsh industrial settings. This translates to longer service life for assemblies exposed to temperature swings, humidity, and chemical exposure. Precisely 1-1/4 inch trade size with female threading and vertical-only sealing orientation simplifies installation and reduces field misorientation. The compact 2.19 in length and 5.06 in height fit tight spaces, while compatibility with the Crouse-Hinds EYD/EZD sealing family streamlines stocking and spares. Compliance and certification are built in: NEC/CEC standards alignment, UL listings for hazardous locations, and explicit area classification support. This reduces regulatory risk during audits and accelerates approvals for new facilities. Implementation notes: use with standard conduit fittings, follow IF 287 installation instructions, and reference the Eaton specification sheet for EYD4. The result is a reliable, code-compliant solution that minimizes rework and supports faster project timelines.

FAQs
To install the EYD4, ensure proper vertical orientation as specified, connect the female 1-1/4" conduit fitting to the mating conduit, and attach the drain-equipped sealing element per IF 287 installation guidelines. Verify area classification compatibility (Hazardous/Classified Locations) and NEC/CEC compliance prior to commissioning. Use compatible Eaton Crouse-Hinds components to preserve explosionproof integrity and minimize rework during retrofits or new installs.
EYD4 is manufactured from ductile iron and/or Feraloy iron alloy, offering robust mechanical strength and corrosion resistance. It is a 1-1/4" trade size female fitting with a vertical sealing position. The unit dimensions are approximately 2.19 in (length) Ă— 2.19 in (width) Ă— 5.06 in (height), and it weighs about 2.32 lb. UPC 782274375403 supports traceability. These specs support reliable operation in Class I/II/III hazardous locations.
Yes. EYD4 is designed for Hazardous/Classified Locations with NEC/CEC standards compliance and UL listings for explosionproof sealing. It covers Class I (Divisions 1 and 2), Class II (Divisions 1 and 2), and Class III environments, aligning with typical refinery, chemical, and petrochemical plant requirements. The drain feature further protects against moisture-related problems in wet or humid installations.
EYD4 carries NEC/CEC standards alignment and UL certifications for explosionproof conduit fittings. Certifications address hazardous locations and the specific Division classifications for Class I, II, and III environments, including both Division 1 and Division 2 where applicable. Area classification guidance and Canada-verified listings are supported via UL documentation, enabling global deployment with reduced audit risk.
The drain feature minimizes moisture buildup, reducing seal degradation and maintenance cycles, which lowers total cost of ownership. The rugged ductile iron or Feraloy iron alloy construction resists corrosion and mechanical wear, extending service life in harsh environments. Standard 1-1/4" sizing and vertical sealing simplify stocking and installation, speeding up project timelines and improving return on investment for facilities upgrading to compliant, explosionproof sealing.
