Abstract
A glide adapter for a lift includes an inner seal extending between the piston rod and glide adapter to prevent leakage of hydraulic fluid which may escape the hydraulic cylinder from seeping from the lift. The sealed glide adapter comprises a generally cylindrical member having an axially extended threaded section for receiving a threaded glide at one end and a cylindrical recess formed at an opposite end, including an undercut recess for snap-receiving a resilient polymeric cylindrical seal which includes an annular groove for receiving an O-ring extending between the outer surface of the seal and the inner cylindrical surface of the glide adapter. The seal includes a blind aperture for receiving one end of the piston rod of the hydraulic cylinder. This design also facilitates servicing of the unit by allowing removal and replacement of the hydraulic cylinder.
