ABSTRACT:
Disclosed is a new dynamic sealing device and a related remote control cable. The device, made of a thermoplastic polyurethane, has a pair of sealing ridges of differing diameter which bear against a rod moving with respect to the outer cable portion, i.e., the conduit. The outer ridge excludes airborne contaminants and the inner ridge retains a synthetic lubricant. The jacket of the cable core is made of nylon 12 which, like the thermoplastic polyurethane and the lubricant, has PTFE as a constituent. The "gap" between the core and the conduit is decreased compared to corresponding prior art cable and the core jacket thickness is about three times that of corresponding prior art cable. Core column strength is about doubled and the new device and cable exhibit a number of other performance advantages as explained in the specification.
