Applications:
6F
EYS and EZS sealing fittings:
• Restrict the passage of gases, vapors or flames from one portion
of the electrical installation to another at atmospheric pressure and
normal ambient temperatures
• Limit explosions to the sealed off enclosure
• Limit precompression or pressure "piling" in conduit systems
Sealing fittings are required:
• At each entrance to an enclosure housing an arcing or sparking
device when used in Class I, Division 1 and 2 hazardous locations.
To be located as close as practicable and, in no case, more than
18" from such enclosures
• At each conduit entrance of 2" size or larger to an enclosure or
fitting housing terminals, splices or taps when used in Class I,
Division 1 hazardous locations. To be located as close as
practicable and, in no case, more than 18" from such enclosures
• In conduit systems when leaving Class I, Division 1 or Division 2
hazardous locations
• In cable systems when the cables either do not have a
gas/vaportight continuous sheath or are capable of transmitting
gases or vapors through the cable core when those cables leave
the Class I, Division 1 or Division 2 hazardous locations
Features:
EYS and EZS sealing fittings include:
• Minimum turning radius
• Large openings with threaded closures to provide easy access to
conduit hubs for making dams
• Integral bushings in conduit hubs to protect conductor insulation
from damage
• Taper-tapped hubs to ensure ground continuity
EYS sealing fittings are available for installation in either vertical only
or in both horizontal or vertical positions.
EZS sealing fittings for installation at any angle; the covers with
opening for sealing compound can be properly positioned to accept
the compound.
