A method and apparatus for forming pressure plugs in cable systems which are under continuous air pressure while maintaining a continuous air flow through the cable. A supplemental air source is connected to the pressurized cable casing on both sides of the area to be plugged to provide an auxiliary air pressure of sufficient quantity to override the normal pressure in the cable casing. Then, the pressure plug may be installed in the cable while the entire cable, and the selected portion of the cable being plugged, remain under adequate pressure to prevent any moisture from entering into the casing.
