Feature: Vertical sealing position is designed for vertical conduit entry only, reducing seal misalignment and maximizing containment integrity. Business impact: improves installation reliability and minimizes retightening cycles, leading to lower maintenance costs. Application: ideal for vertical conduit runs in chemical plants and offshore platforms where gravity-assisted sealing matters. Feature: Ductile iron with Feraloy iron alloy construction delivers superior mechanical strength and corrosion resistance. Business impact: extends service life in harsh environments, lowering replacement intervals and total cost of ownership. Application: suitable for rugged industrial setups with exposure to moisture and corrosive atmospheres. Feature: 3/4" trade size with male and female configurations provides versatile pairing with common conduit systems. Business impact: simplifies spares management and accelerates field assembly, reducing project lead times. Application: retrofit or new-install projects across a range of electrical enclosures and conduit branches. Feature: Group B rated and NEC/CEC compliance address hazardous location requirements. Business impact: mitigates regulatory risk and supports safer downtime activities. Application: essential for installations in Class I, II, and III locations such as refineries, petrochemical facilities, and mining sites. Feature: Comprehensive documentation and CAD resources (3D drawing package, installation sheets, datasheet) streamline engineering workflows. Business impact: enables faster design validation and accurate field installation, lowering project risk. Application: engineering teams leveraging CAD workflows and supplier approvals for hazardous-area projects.

FAQs
Installers should verify the vertical orientation specified for EYS26, mate the male and female ends securely, and follow the IF 287 conduit sealing guidance. Ensure the conduit size is 3/4" and that the mounting surface supports the vertical seal. Use the provided CAD drawings to confirm layout before field assembly to minimize resealing and downtime.
The EYS26 is designed for NEC/CEC compliance and is rated for Hazardous/Classified Locations, including Class I Division 1 and 2, Class II Division 1 and 2, and Class III. It is UL-certified for use in hazardous locations in the US and Canada, aligning with industry standards for safe operation and installation.
Yes. The EYS26 is part of the Crouse-Hinds EYS family and is designed to integrate with other EYS and EZS explosion-proof conduit sealing fittings. This compatibility simplifies standardization across projects and supports consistent performance in hazardous environments.
The EYS26 uses ductile iron with Feraloy iron alloy, delivering high mechanical strength and corrosion resistance. This combination provides long service life in demanding facilities, reducing replacement frequency and maintenance costs while maintaining seal integrity under tough operating conditions.
Installation instructions are available in Eaton’s IF 287 document, along with the Eaton Specification Sheet for EYS26. Additional resources include the 3D CAD drawing package and catalog pages for the EYS/EZS series, plus UL certification reports for US and Canada, to support compliant and efficient commissioning.
