An ingress prevention system for use with pneumatic or hydraulic jack cylinders prevents debris and/or fluids from gaining access to portions of the pneumatic or hydraulic jack cylinders. The ingress prevention system includes a boot operable to retain and/or seal at least a portion of one or more jack cylinders within a boot cavity. The ingress prevention system reduces a jack cylinder's exposure to debris and/or fluids to maintain performance and prolong the operating life of the jack cylinder. The ingress prevention system further comprises at least one barrel seal operable to wipe debris and/or fluids from the surfaces of a piston rod as the piston rod reciprocates within a barrel.

A saddle and removable extension for a floor jack having a storage assembly is disclosed. A saddle and extension assembly of the floor jack includes a jack saddle fastened to a mounting bracket of a lifting arm and an extension having a flange and an extension saddle. To withstand off-center loading conditions when the floor jack is in an upper extended position, at least one extension fastener is operable to engage with at least one extension bore by fastening the extension to the jack saddle and the mounting bracket of the lifting arm. A storage assembly is provided on a body of the floor jack to house the extension during storage or transport.
