Crouse-Hinds series EYDX expanded fill sealing fittings with drains provide 40% wire fill capacity to allow uninterrupted runs in a conduit system. In addition to restricting the passage of gases, vapors or flames from one portion of the electrical installation to another, EYDX sealing fittings prevent accumulation of condensate above the seal. They are installed in vertical conduit runs and at low points in conduit systems.
