Product DescriptionThe ABB EYS11-TB is a 1/2 inch EYS-style sealing fitting designed to seal conduit systems against the passage of gases, vapors, and flames in hazardous locations. The body is constructed from ductile iron, the plug from gray iron, and the nipple from steel, delivering durable performance in demanding industrial and commercial environments. This fitting is installed by licensed electricians working on conduit runs that require code-mandated sealing at enclosure entries or boundaries between hazardous and non-hazardous areas.This sealing fitting is suited for use in classified hazardous locations such as Class I Division 1 and Division 2 installations where conduit sealing is required by the National Electrical Code. Typical applications include oil and gas facilities, chemical processing plants, wastewater treatment sites, and industrial manufacturing environments. It is sized for 1/2 inch conduit and is intended for use with a sealing compound that is poured or injected to complete the seal.Key Features1/2 inch trade size for standard conduit installationsDuctile iron body for impact resistance and long service lifeGray iron plug for secure sealing compound retentionSteel nipple for robust conduit connectionEYS-style design suited for hazardous location conduit sealing requirementsCompatibilityDesigned as an OEM-style replacement or direct-install sealing fitting for 1/2 inch rigid or intermediate metal conduit systems in hazardous location applications.Installation NotesInstallation must be performed by a qualified electrician in accordance with NEC Article 501 and applicable local codes governing hazardous location wiring. De-energize all circuits in the affected conduit run before beginning work. The fitting must be filled with an approved sealing compound after installation and before the system is returned to service. Do not use this fitting without completing the sealing compound fill, as an unsealed fitting does not provide the required gas or flame barrier.Technical SpecificationsTrade Size: 1/2 inchBody Material: Ductile IronPlug Material: Gray IronNipple Material: SteelUPC: 786210248066Standard InformationBrand: ABBManufacturer Part Number: EYS11-TB
