Abstract
Apparatus and method for lubricating cables, such as speedometer cables, disposed within a tubular sheath. The apparatus comprises a coupling adapted for releasable securement to one end of the cable and includes a passageway having an outlet in communication with the interior of the cable sheath when the fitting is secured to the coupling. A pressurized container of a low viscosity lubricant is included in the device as is an on-off valve. The valve is arranged to allow an aerosol of the lubricant to be carried from the container into the coupling and from there along the entire length of the annular space between the cable and its sheath under the pressure applied by the gas to effect the lubrication of the cable.
