Abstract
A non-pressure head for a fluid cylinder, which includes a drain channel formed in the flange by a raised portion of the flange extending from a plane of the flange in the same direction as the head portion. The channel is cold formed in the flange. For the piston stop, the flange has an opening of a diameter smaller than a diameter of a piston on the piston rod to form a stop for the piston. A plurality of spaced ribs are provided between the flange and the head. The ribs are raised portions of the flange and the head and are cold formed in the flange and the head.
