Abstract
A unique air vent is provided for use with heat-recoverable closures when installed on pressurized cables. Typically, when a heat-recoverable closure is used to repair a hole or opening in the jacket of a pressurized cable the cable must be depressurized during installation of the closure to ensure formation of a pressure and watertight seal. The air vent assembly permits installation of a heat-recoverable closure without the need for depressurizing the cable. After installation, the air vent can be used as an access point to the pressurized air within the cable.
