3/Eight inch Nylon ferrule & Brass tube insert



Used to Convert our 3/eight brass compression fittings for use with 3/eight John Guest tube. This simple conversion enables the heat resistant John Guest tube to be attached directly to the water heating panel and the circulating pump and can be used anywhere to join 3/eight tube in your system. The nylon ferrule replaces the brass olive supplied with the compression fitting and the brass insert stops the JG tube from distorting and leaking when used with hot water. First, slide the compression nut on the tube then the nylon ferrule with the tapered side toward the fitting, then push the brass insert into the end of the tube. This easy and neat conversion forms a leak-proof seal with a minimum of torque required when tightening the nut. When priming the system after installation this mechanism can practically form a leak-proof seal when only finger tight
