Sealing fittings are installed in conduit runs to minimize the passage of gases, vapors, or flames from one portion of the electrical
installation to another through the conduit, as well as to prevent precompression or "pressure-piling" of vapors or gases in conduit systems.
NOTE:
Seals should be made only by experienced, careful persons in strict compliance with these instructions. Even slight variations can
cause serious field problems. Read directions completely.
DIRECTIONS FOR INSTALLATION
Using the drawings and chart at the right as a guide, install the sealing
fitting into the conduit system. Refer to the National Electrical Code,
Articles 501-5 and 502-5 for the regulations covering your specific
application.
Pull the conductors (wires) through the conduit system.
Using Packing Fiber, build a dam at each conduit hub (except upper hubs
in vertical seals.) Use a wooden stick to force the wires apart, and pack
the fiber tightly around all wires. The dam must be tight and strong
enough to keep the liquid sealing compound from leaking out before it
sets up. The completed dam should be even with the conduit stop.
Use the included Sealing Compound with these fittings. The sealing
compound is mixed with water at the rate of three (3) parts of sealing
compound to one (1) part of water by volume. See chart to determine
the amount of compound required for a specific fitting. Use a clean
mixing vessel for each batch. Sprinkle the sealing compound into the
water while stirring, until a thick paste is formed. Continue mixing for AT
LEAST THREE (3) MINUTES.

minutes. Discard any material that becomes too stiff to use. Never
attempt to restore workability by stirring in more water.
After the compound is mixed, slowly pour it into the sealing fitting to the
required level. Make sure that the wires are well separated, so the
compound completely surrounds them. Pour slowly to avoid trapping air
bubbles in the compound. Immediately wipe any spilled compound from
conduits and threads, and close the fitting with the close-up plug. Make
sure the plugs are tight.
Initial set of the sealing compound will occur within thirty (30) minutes.
However, the compound requires a minimum of 8 hours above 32° F to
develop sufficient strength to withstand explosion pressures.
