Thomas & Betts EYS51-TB Conduit Sealing Fitting

Description:

The Thomas & Betts EYS51-TB Conduit Sealing Fitting is used in hazardous location conduit systems to prevent the passage of gases, vapors, and flames through threaded rigid conduit while maintaining the integrity of explosion-proof electrical installations. Commonly installed in oil and gas facilities, chemical processing plants, refineries, grain handling facilities, power generation plants, and other Class I, II, and III hazardous locations requiring explosion-proof conduit sealing. Maintenance electricians, industrial contractors, OEM manufacturers, and system integrators use this sealing fitting for new installations, hazardous area retrofits, conduit maintenance, and replacement of existing conduit seals.

Applications:

The Thomas & Betts EYS51-TB is designed to seal conduit runs using approved sealing compound, preventing the migration of explosive gases, vapors, or flames while minimizing pressure piling during an internal explosion. It is widely used on motors, junction boxes, process equipment, control panels, petrochemical facilities, mining operations, and industrial manufacturing plants where explosion-proof conduit systems are required. The EYS51-TB is suitable for both vertical and horizontal conduit installations.
