AGS is the industry leader in the automotive aftermarket for steel brake, fuel, and transmission lines. This 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. The finished tube is fused and zinc-coated to provide excellent rust and corrosion resistance as well. The AGS Standard Steel line has been the choice of professional installers/mechanics and do-it-yourself mechanics for many years. When properly installed, the standard steel line can provide a long-lasting repair or replacement for many types of vehicles and for all types of fluid transfer systems, including braking systems. However, when a vehicle is expected to see harsh environments like snow, road treatments, salt air, etc...on a regular basis or when the longest replacement life is required; other AGS premium lines like Poly-Armour and NiCopp should be considered.
