The connecting portion includes a neck and a cap head with the cap head connected to an end of the neck disposed opposite the piston rod body. The cap head is wider than the neck. A mounting portion of the piston rod body extends into a receiving portion of the cap body to connect the piston rod body to the piston cap.
