1.0 General Product Information
The TDUX inflatable duct sealing system is a wraparound, inflatable, mastic-lined bladder
used to seal empty or filled cable ducts. When inflated to the proper air pressure, the TDUX
duct sealing system seals the duct, guaranteeing a reliable water block. TDUX systems
seal ducts with or without cables and can be installed even while water is flowing out of the
duct.
TDUX duct seals can be installed in cable ducts in manholes, vaults, buildings, cabinets, or
anywhere a reliable duct seal is needed. Applications include ducts containing multiple
copper, coax, or fiber cables, customer premises cable entrances, and air pipes.
TDUX duct seals can be installed between (-5°to 40°C) (23° to104°F). It is recommended
that the TDUX sealant bag and gas cylinders be kept warm until installation when installed
at temperatures below freezing.
2.0 Cautions/Warnings
DANGER: Do not inflate TDUX duct seal unless it is installed in a pipe!
Lubricant
1.
Protect TDUX sealing lubricant from freezing. If lubricant gets in eyes, flush eyes with
clean water for 15 minutes, holding eyelid open. Wash skin with mild soap and water if
skin irritation occurs. Seek medical attention if irritation persists.
2.
Use only TDUX sealing lubricant or company-approved lubricant. Use of non-approved
lubricants can result in damage to the cable or the TDUX duct seal.
Gas Cylinders
If the carbon dioxide gas cylinders are used to inflate the TDUX duct sealing system, the fol-
lowing safety rules should be considered:
1.
The gas pressure in the cylinder is approximately 900 p.s.i. (60 bar) at room tempera-
ture. Maximum operational temperature is 122°F (50°C).
2.
Keep cylinders cool and dry. Use only as instructed in the operating manual of TDUX-IT-
16 inflator. Misuse can be dangerous.
3.
Do not handle the cylinder with unprotected hands immediately after filling a TDUX duct
seal. Frostbite can result.
