Those are the type of fittings that I would use not the fittings that are just push on with barbs and I believe that those are the fittings that people out there are having problems with not the type shown in the PDF you posted. Also at the end of the PDF it says to proof the fitting at twice the pressure and I am sure that the DIY people do not have the setup to do that. Just make the hose and slap it on. So here again I say have a shop put the fittings on, they have the equipment and will do a static pressure check of the lines for leaks. Just my opinion. Or you can purchase all the tools to do it your self correctly $$$$$$.
