EYS and EZS IECEx Conduit Sealing Fittings

Crouse-Hinds series sealing fittings designed and certified for IEC hazardous areas.  EYS, EYSA and EZS sealing fittings restrict the passage of gases, vapors or flames from one portion of the electrical installation to another, limit explosions to the sealed off enclosure, and limit pre-compression or “pressure piling” in conduit systems.

EYS and EYSA sealing fittings are available for installation in either vertical only or in both horizontal or vertical positions. 

EZS sealing fittings are designed for installation at any angle; the covers with opening for sealing compound can be properly positioned to accept the compound.
