This tube is double walled, 720 degree seamed by copper brazing, coated with PVF (polyvinyl fluoride).
PVF is coated on top of the galvanized dual welled steel tubing, offering superior corrosion resistance than any type of zinc or zinc alloy platings.
It is used for aftermarket replacement of brake line, fuel line, transmission cooler line, and other low/medium pressure fluid/air transfer, made to SAE J527, ASTM A254, JASO M101, GOST 11249, IS 8119 etc. general standards for automotive hydraulic tubing.
The tube is easy to bend and flare, suitable for SAE 45 degree inverted flare/ISO double flare, ISO/DIN bubble flare, ISO single flare etc.
