It permits cable movement while retaining its sealing properties. The TDUX system has been tested in severe environmental conditions and is air-tight up to 7 psi (50kPa). The TDUX duct sealing system is water-tight in depths up to 16 ft. (5m).
The T-DUX-100-KIT-ENGL (894743-000) is designed for use in 4" diameter ducts with a maximum cable or innerduct OD of 3".
