Unions, Sealing Fittings, Flexible Couplings,
Elbows, Drain/Breather, Close-Up Plugs:
Explosionproof
UNILETS
®
for Use with Threaded Metal Conduit
Features: All Fittings
•
Explosionproof, dust-ignitionproof.
•
Smooth, rounded integral bushing in
each hub protects conductor insulation.
•
Accurately tapped, tapered threads for
tight, rigid joints and ground continuity.
Features: Non-Expansion Unions
❶ Concentric ring interlocked design of
1/2”, 3/4” and 1” sizes makes possible
smaller diameter, allowing use in tight-
er spaces. 1-1/4” and larger UNY sizes
have removable male nipple.
•
Choice of malleable iron or alumi-
num
.
Features: Expansion Unions
❷ One-piece design eliminates need
for disassembly during installation.
•
Telescoping cylinder within cylinder
design permits expansion or contraction.
•
Standard or long types available.
•
Small external diameters—excellent
in restricted areas in wiring of pumps,
motors, and other equipment.
•
Internal phosphor bronze “bonding
jumper” ring assures positive ground
between telescoping cylinders.
Features: Sealing Fittings
❸ Raintight construction.
•
Removable nipple in male sealing
fitting may be used interchangeably in
top or bottom hub.
•
EYS—for sealing vertical conduit.
Large opening for damming and filling.
•
Expanded Fill EYSEF/EYDEF— allow
up to 40% conduit fill in compliance
with the National Electrical Code.
•
EYSF/EYSM—for sealing vertical con-
duit. Large opening for damming and fill-
ing.
•
ESUF/ESUM for sealing vertical
or horizontal conduit. Pouring spout
rotates
90° Removable cover provides
full access
for damming 2-1/2” thru 4”
sizes have threaded cover openings
for damming.
•
EYF/EYM—close radius type for seal-
ing vertical or horizontal conduit runs
.
•
EYDM Drain Sealing Fittings—close
radius type for sealing vertical conduit
runs. Access cover has drain valve for
automatic draining of water accumula-
tion above the seal.
•
Kwiko
®
A sealing cement is a specially
formulated water soluble powder. Mixed
to the proper proportions, it is poured in
sealing fittings and hardens to contain
and restrict the passage of gases and
explosions in classified areas
.
•
Fiber Filler-makes dams around
and between all conductors to prevent
sealing compound from leaking while
being poured in its liquid state.
Features: Sealing Hubs
❹ UL Listed for use in hazardous
locations when Kwiko
®
A Sealing
Compound or Crouse-Hinds Chico
®
A
Sealing Compound are used to make
the seal.
Features: Flexible Couplings
❺ Heavy duty design resists mechani-
cal abuse. Watertight.
•
Electrical conductivity equal to rigid
conduit on a similar length basis—no
bonding jumper required.
•
Interior insulating liner protects con-
ductors from abrasion under vibrating
conditions.
•
EXGJH—both end fittings are female,
each furnished with a removable male
nipple.
•
EXLK—female end fitting with union at
one end and a female end fitting with a
removable male nipple at the other end.
