Copper-brazed, double-walled, steel tubing. When combined with AGS tube nuts (included) and flaring tool, 25 foot lengths are an economical solution for shops that want to build their own lines, custom lengths or non-standard applications. The entry-level replacement line is an excellent choice for aftermarket fluid transfer line repair and replacement. The steel lines and tubing are constructed with safety and longevity in mind. The tubing is produced by wrapping copper-coated steel around itself twice to form the tubing. This double-wall tube is what provides the strength and structural integrity to withstand the extreme pressures required, yet still remain pliable enough to be formed and bent to the shapes required to be routed beneath the vehicle.
