INSTRUCTION FOR UL LISTED EYAX AND EYDX SERIES EXPANDED FILL
SEALING FITTINGS APPROVED FOR USE WITH:
®
APPLETON "Kwiko
• The National Electrical Code in Article 501 Section 501.15 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.
• O-Z/Gedney sealing fittings are UL listed for use in hazardous locations with Appleton 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 A and CROUSE-HINDS Chico A CEMENT
FOR GROUPS C AND D APPLICATIONS: Sealing compound to
be mixed ONLY at temperatures above 35º F (1.7º C) and ONLY
Mineral Fiber Filler
“Asbestos Free”
STEP 1.
Install sealing fitting 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 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.
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 sealing fitting 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 sealing fitting and the small pipe plug
into the cover.

Be sure to read the mixing
instructions on Sealing cement can.
poured into fittings that have been brought to a temperature above
35º F (1.7º C). Seals must NOT be exposed to temperatures below
35º F (1.7º C) for a least 8 hours. Compound must be allowed 8
hours to cure to full strength before energizing system.
FOR GROUPS A AND B APPLICATIONS: Sealing compound to
be mixed ONLY at temperatures above 40º F (4.4º C) and ONLY
poured into fittings that have been brought to a temperature above
40º F (4.4º C). Seals must NOT be exposed to temperatures below
40º F (4.4º C) for a least 72 hours. Compound must be allowed 72
hours to cure to full strength before energizing system.

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.
Vertical conduit
1. Install sealing fitting 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 sealing fitting.
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" sealing fitting, 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 sealing fitting and pull conductors through.
2. Remove all pipe plugs and / or cover from the sealing fitting.
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 sealing fitting through the
large opening until 2-3 threads are covered with the cement. Fill
hole must be oriented in the upright position.
6. Replace and tighten in sequence the large pipe plug or cover,
the small pipe plug into the sealing fitting and the small pipe
plug into the cover.
1. Install sealing fitting and pull conductors through.
EYDX Series 1" TO 4"
2. Remove the large threaded cover from the sealing fitting.
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 sealing fitting 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 threaded
hole and tighten securely.
