CABLE SEALING UNIT WITH SEALED ACTUATOR

摘要

A cable sealing unit has an actuator that is sealed to inhibit the intrusion of debris from compromising the working components of the actuator. A sealant can be pressurized using an actuator that includes a handle threaded over a shaft to compress a spring. A sealing arrangement is disposed at the actuator to prevent a particulate contaminant, such as sand, from damaging the threads of the actuator. The sealing arrangement also can prevent the spring from being exposed to particulate contaminants. The sealing arrangement can include one or more sealing members disposed on the handle and/or the shaft.
