Abstract
A piston rod-cylinder assembly, such as a gas spring, includes a cylinder in which a piston rod is axially movable and connecting members on the cylinder and the piston rod for attachment of the assembly in use. The cylinder and an axial portion of the piston rod are covered by a shrink-wrap sleeve for corrosion protection and/or coloration. A lubricant layer is provided between the cylinder and the shrink-wrap sleeve adjacent one or both ends of the cylinder.
