Earl's Performance AT165056ERL Clamp-On Hose Fitting

These look great, perform perfectly and are easy to install--unless you make it complicated. There is no information on Earl's website showing how to install these. I guess it's assumed that everybody knows how to install compression fittings. But do an on-line search and you'll find lots of questions and few correct answers. Bottom line, don't flare the tube! Simply slide the nut and ferrule over the line, put the fitting over the end of the line, finger tighten the nut, then tighten it about one full turn with a wrench. The ferrule is pushed into the fitting compressing the line and creating a tight, leak-proof seal. These fittings are a great way to terminate hard lines with -AN fittings.
