Applications:
EYD drain and EZD drain and inspection
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
• Prevent precompression or "pressure
piling" in conduit systems
Drain sealing fittings are installed in vertical
conduit runs and at low points in conduit
systems to prevent accumulation of
condensate above seal.
For sealing fitting requirements
see page 145.
Features:
EYD and EZD drain sealing fittings include:
• Drain to provide continuous, automatic
drainage of condensate
• Large openings with threaded closures
to provide easy access to conduit hubs
for making dams
• Integral bushings to protect conductor
insulation from damage
• Taper-tapped hubs to ensure ground
continuity
EZD drain and inspection sealing fittings
also include:
• Removable covers for periodic
inspection of seals
• Barrier for sealing compound easily
installed after dams are made and
before compound is poured.
Standard Materials:
• Bodies, and inspection or drain covers –
Feraloy? iron alloy and/or ductile iron
• Closure for drain – copper-free
aluminum or ductile iron
• Small closure plug – Feraloy iron alloy
and/or steel
• Drain – stainless steel
• Removable nipples – steel
