A pressure fluid cylinder with anti-rotation feature, includes a cylinder tube of non-circular inner cross section and a piston which is sealingly received in the tube. The piston has a circular cross section and is connected at one end to a piston rod in coaxial relationship. In order to allow selective use of the pressure fluid cylinder with or without anti-rotation feature, an annular adapter is placed between the piston and the tube and has a circular inner surface area to complement a circular outer surface area of the piston so as to allow a relative rotation between the piston and the adapter. The adapter has a non-circular outer surface area to complement the non-circular inner surface area of the tube. Through insertion of a fastener in aligned boreholes of the adapter and the piston, the adapter and the piston are prevented from rotating relative to one another.
