"Asbestos
Free" Sealing
Cement. Be
sure to read the
mixing instructions on Sealing
cement can.
STEP 1.
Install unilet and pull conductors through.
• Remove plug(s) from sealing fitting and
use fiber filler to make dam (s) in hub(s).
STEP 2.
DAMMING: Separate each conductor and
pack fiber filler tightly into hub(s) behind
conductors and around each conductor.
• These conductors must not touch each
other nor the sealing fitting wall.
• Clean fiber shreds away from walls or
conductors to prevent them from causing
flame and / or leakage of gases. Finished
dam must be flush with conduit hub
bushing.
STEP 3.
MIxing: Prepare sealing compound using a completely
clean mixing vessel in each batch. Shake the sealing
cement thoroughly in all directions. Mix sealing cement
with correct proportion of clean water as noted below.
APPLETON Kwiko CEMENT. Add 3 fluid ounces of water
to 1 lb. of cement, equivalent to 1 part water to 3 parts
cement by volume, for a minimum of 5 minutes or until an
even pouring consistency is obtained.
APPLETON Kwiko A and CROUSE-HINDS Chico A
CEMENT. Add one (1) part water to two (2) parts cement
by volume. Use cold water, warm water increases setting
speed. Add water and stir immediately and thoroughly.
• DO NOT mix more than can be poured in 15 minutes after
adding water.
• These cements are NOT INSULATING COMPOUNDS
and MUST NOT be used for such purposes.
CAUTION
Refer to Table 1 to determine the
maximum number and size of conductors allowed in a seal. (Page 4)
STEP 4
VERTICAL CONDUIT RUN. Pour sealing cement mixture into
the small pipe opening until the cement is level with the last
thread of the opening. Replace and tighten small pipe plug.
HORIZONTAL CONDUIT RUN. Pour sealing cement mixture
into the Unilet through the large opening until two (2) to three
(3) threads are covered with the cement.
• Replace and tighten in sequence the large pipe plug or cover
the small pipe plug into the Unilet and the small pipe plug into
the cover.

INSTRUCTION SHEET
INSTRUCTION FOR UL LISTED EYSEF AND EYDEF SERIES
EXPANDED FILL SEALING FITTINGS APPROVED FOR USE
WITH: APPLETON Kwiko®, Kwiko A™AND
CROUSE-HINDS Chico A®SEALING CEMENT
• The National Electrical Code in Article 501 Section 501-5 Class I, Division 1 and 2, requires that seals be installed in specific
locations. This is to prevent the passage of gases, vapors or flames through the conduit from one portion of the electrical installation to another portion.
• Appleton sealing Unilets®are UL listed for use in hazardous locations with Appleton Kwiko, Kwiko A, or Crouse-Hinds Chico A
compound only. These compounds, when properly mixed and poured, harden into a dense and strong mass which is insoluble
in water, is not attacked by petroleum products and is not softened by heat.
WARNING:
Failure to follow safety instructions may
cause ignition of hazardous atmosphere
resulting in serious personal injury and / or
property damage.
CAUTION: Temperature / Cure Time
Appleton Kwiko Cement must not be mixed and poured at
temperature below 350F (1.70C).
Cement compound curing time varies with temperatures.
Examples are: 35oF (1.70C) - 24 hrs., at 680F (200C) - 4 hrs.
APPLETON Kwiko A and CROUSE HINDS Chico A
CEMENT
FOR APPLICATIONS INVOLVING GROUP C AND D
CAUTION: Sealing compound to be mixed ONLY at temperatures above 35oF (1.70C and ONLY poured into fittings that
have been brought to a temperature above 35oF (1.70C).
Seals must NOT be exposed to temperatures below 35oF
(1.70C) for at least 8 hours.
FOR ALL APPLICATIONS
CAUTION: Sealing compound to be mixed ONLY at temper-
atures above 400F (4.40C) and ONLY poured into fittings that
have been brought to a temperature above 400F (4.40C).
Seals must NOT be exposed to tempertures below 400F
(4.40C) for at least 72 hours.

Vertical Conduit
EYSEF SEALING UNILETS 1/2" TO 4
Vertical conduit
1. Install Unilet and pull conductors through.
2. Remove the pipe plug where the cement will be poured
through and the large pipe plug or cover with the small pipe
plug for size 3", 3-1/2" and 4" at the center of the Unilet.
3. Dam the lower hub with fiber filler. (Page 1, Steps 1 & 2.)
4. Replace the large pipe plug or cover with the small pipe
plug for 3", 3-1/2" and 4" Unilet, tighten all threaded joints
securely.
5. Mix Sealing Cement with the correct proportion of water
per instructions provided with the cement. (Page 1, Step 3).
6. Pour Sealing Cement mixture into the small pipe plug opening until the cement is level with the last thread of the opening.
7. Replace and tighten small pipe plug.
Horizontal conduit
1. Install Unilet and pull conductors through.
2. Remove all pipe plugs and / or cover from the Unilet.
3. Dam both hubs with fiber filler. (Page 1, Steps 1 & 2)
4. Mix Sealing Cement with the correct proportion of water per
instructions provided with the cement. (Page 1, Step 3.)
5. Pour Sealing Cement mixture into the Unilet through the
large opening until 2-3 threads are covered with the cement.
6. Replace and tighten in sequence the large pipe plug or
cover, the small pipe plug into the Unilet and the small pipe
plug into the cover.
NOTE: On sizes 3", 3-1/2" and 4" the cover should be tightened down with the small pipe plug removed from it. This will
allow excess cement or air to escape out rather than seeping
through or pushing the dam into the conduit. When the large
cover has been tightened fully, replace pipe plug.
CAUTION
Remove any cement from threads in order to allow a minimum of 5 threads engagement of fitting threads, close plug
and drain / breather.

1. Install Unilet and pull conductors through.
2. Remove the large threaded cover from the Unilet.
3. Dam the lower hub opening with fiber filler. (Page 1, Step
2).
4. Replace the large threaded cover so that the threaded hole
is facing downward.
5. Insert the tube and wire drain core into the opening of the
large threaded cover so that the end being inserted will be
above the compound in a completed seal. (See illustration on
this page).
6. Be sure that the tube and wire drain core do not touch any
of the conductors, Otherwise, this will expose the conductors
in the completed and hardened seal. (See illustration on this
page).
7. Mix Sealing Cement with the correct proportion of water per
instructions provided with the cement. (Page 1, Step 3).
8. Pour Sealing Cement mixture into the Unilet through the
opening located above the large cover until the last thread is
covered with cement.
9. After cement has cured, (see page 1, "Caution: For temperature / cure time") pull out the old tube and wire drain core
and discard.
10. Thread the small pipe plug into this opening and tighten .
11. Thread ECDB drain-breather fitting into large cover thread-
ed hole and tighten securely.
