Eaton Crouse-Hinds EYD81 Conduit Sealing Fitting - Group B Rated
Part Number: EYD81
Quick Summary
Conduit sealing fitting is designed to seal and drain conduit entries for hazardous-location installations in industrial facilities. Engineers often battle moisture ingress and strict NEC/CEC compliance, risking downtime and equipment damage. This EYD81 unit supports hazardous/classified locations with a Group B rating, as well as NEC/CEC standards, UL certifications, and a durable ductile iron/ Feraloy iron alloy construction. Vertical-only sealing position helps maintain predictable drainage paths, and its 3" trade size matches common field conduit runs. By selecting this fitting, maintenance teams reduce moisture-related failures and simplify inspection cycles, while integrators benefit from a proven, code-compliant solution that supports fast installation and robust long-term reliability in harsh environments.

Feature → Business Impact → Application: The EYD81 uses a ductile iron and/or Feraloy iron alloy body, delivering enhanced ruggedness and corrosion resistance that lower maintenance costs and extend service life in harsh environments. This translates to fewer field calls and longer intervals between replacements in chemical plants and outdoor installations where moisture and dust are prevalent. Application: Ideal for explosion-protected conduit runs in hazardous locations requiring durable, compliant sealing.Feature → Business Impact → Application: Vertical sealing position with drain reduces water accumulation inside conduits, minimizing corrosion risk and ensuring reliable electrical connections during washdowns or rain events. Application: Suitable for outdoor installations and process areas where gravity-assisted drainage is advantageous.Feature → Business Impact → Application: 3" female trade-size coupling aligns with common field assemblies, simplifying spares and reducing installation time. Application: Fast integration with standard Eaton Crouse-Hinds sealing fittings in new builds or retrofit projects in mining, oil & gas, and chemical processing.Feature → Business Impact → Application: Group B rated and NEC/CEC compliance provide regulatory assurance and safer operation in Class I/II/III environments, lowering risk of non-compliance penalties and retrofit costs. Application: Suitable for plants with strict safety regimes and third-party audits.Feature → Business Impact → Application: Integrated drain and horizontal/vertical compatibility support easier maintenance schedules and reduced downtime during inspections. Application: Maintenance teams gain predictable performance during routine checks and after-incident investigations.Feature → Business Impact → Application: Availability of installation resources such as IF 287 guidance and official datasheets accelerates project timelines and minimizes guesswork. Application: Engineering teams can reference authoritative installation steps for quick, code-compliant deployments.

FAQs
The EYD81 is a female 3 inch conduit sealing fitting designed for hazardous locations, with vertical sealing and drain features. It uses ductile iron and Feraloy alloy for rugged durability and NEC/CEC compliance. When planning installation, confirm proper enclosure ratings, oriented drainage, and compatible conduit couplings to ensure full compliance and reliable operation in a hazardous environment.
EYD81 carries NEC/CEC compliance and a Group B rating suitable for Class I, Division 1 and Division 2, Class II, and Class III locations. It is designed for hazardous/classified locations and has UL certifications for explosionproof conduit sealing fittings with drain, providing regulatory assurance and safer field operation.
Yes. The EYD81 specifies a vertical sealing position, which supports directional drainage and reduces moisture retention inside the fitting. This orientation is particularly advantageous in outdoor and process environments where gravity-assisted drainage helps maintain long-term reliability.
By combining NEC/CEC compliance, Group B hazardous location rating, and a robust ductile iron/Feraloy construction, the EYD81 minimizes non-compliance risk and reduces maintenance frequency. Its drain feature prevents moisture buildup, lowering corrosion-related downtime and extending service life in demanding industrial plants.
