Since the return side of a PS system sees little or no pressure then that hose will work fine. I used some -6 teflon hose and steel fittings to make up a pressure hose for my race car. I used rubber hose that was compatable with PS fluid for the return side. I only used crimp connectors to secure the hose to the barbed fittings.
