Applications:
Standard Finishes:
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
• Feraloy iron alloy and ductile iron – electrogalvanized and
aluminum acrylic paint
• Steel – electrogalvanized
