Abstract
A method of sealing a cable penetration includes assembling a cable seal and inserting the cable seal into a cable penetration. Assembling the cable seal includes adhering at least a portion of a heat-shrinkable tubing to at least a portion of a cable outer jacket, and positioning a secondary elastic seal over the heat-shrinkable tubing. An example of a secondary elastic seal could be O-rings. A cap or other means provides the outer sealing surface.
