Abstract
A jacket-assembly is sealed to a hydraulic elevator jack to protect the jack from corrosion. The jacket-assembly is preferably manufactured from a non-galvanic, non-corrosive material, such as high density polyethylene tubing. The jacket may be manufactured from any non-galvanic, non-corrosive material that is strong enough and flexible enough to be factory-installed on the jack. The jacket is preferably hermetically sealed to the jack. The jacket-assembly may contain a bulkhead mounted on the hydraulic elevator jack having an O-ring groove. An O-ring can be used to effect a hermetic seal between the bulkhead and the jacket. The bulkhead may be mounted on the jack with any conventional means, such as a weld. In one embodiment, a moisture sensor may be placed inside the jacket.
