Pack-Seal Connection Instructions 

A conduit seal is necessary for most equipment enclosures in hazardous areas. For Z-

purge, they are always required. Please consult your local code for other instances and 

full details. 

ALWAYS follow all NEC, NFPA, and local codes when installing conduit and pack-seals 

in hazardous areas!

 It is 

very important

 that knowledgeable personnel, familiar with 

national and local codes, supervise hazardous area equipment installations.

 

 

The sealing compound generally used for pack-seals is an inorganic, chemically setting, 

magnesium oxide base material, which develops a slight expansion while hardening 

into a porcelain-like body. Sealing Compound is supplied as a powder and need only 

be mixed with water to apply. Approximately one ounce of sealing compound is 

needed per cubic inch of space to be filled. 

The sealing compound powder has a shelf life of six months when stored in unopened, 

tightly sealed containers in a dry location at 70

°

F. 

Any equipment accidentally splashed with sealing compound should be cleaned with 

soap and water before the sealing compound cures. 

 

Equipment Required 

 

Four PAC-Seal fittings, 1” NPT or 0.75” NPT for the Z-Purge, or sealing conduits.  The PAC Seal 

and conduit size selected will depend on the size and number of conductors, which must be 

run to the unit.  Check the NEC tables (Chapter 9, Table 4) to determine the conduit size 

necessary 

 

Conduit for electrical signals and for electrical power (separate runs), NEC and NFPA approved 

for use in hazardous areas 

 

NEC and NFPA approved flexible conduit if needed for difficult installations 

 

Fittings as required for permanent conduit installation NEC and NFPA approved for use in 

hazardous areas 

 

Signal cables, power cables, and connectors as required to mate with the equipment within 

the enclosure or cast aluminum box 

 

AC   power switch for use in the safe area 

 

Procedure 

1.

 

Threaded surfaces and pour locations should be cleaned with soap and water and thoroughly 

dried before proceeding. 

2.

 

On a Z-purge system, no entryway is provided by DAISY for power and signal conduits. These 

entries must be made by the end user. Select a point on the enclosure that matches well with 

the location of the incoming conduit. 

Be careful to ensure that the point you have selected 

is free from obstructions within the DAISY enclosure

.

 Being careful to protect the internal 

electronics, air pathways, and keyboard surface from flyings and other debris, drill, or punch 

holes for the installation of the Pack-Seal fitting (1” NPT or 0.75” NPT, depending on 

application) in the wall of the enclosure.
