CS-Lok® tube fittings are fully interchangeable with Parker CPI™. Although it is always recommended to use all CS-Lok® components, intermixing CSLok® bodies and/or component parts with those of other manufacturers will not adversely affect sealing ability. CS-Lok® Tube Fittings are made to strict quality control standards and cannot guarantee that of other manufacturers. CS-Lok® Tube Fittings are proudly made in the U.S.A.
