Kit Contents: 1 25 ft. coil 1/4 in. NiCopp tubing; tube nuts for SAE thread, inverted flare as follows: 10 7/16 in. X 24 long, 2 7/16 in. X 24 short, 2 9/16 in. X 18, 2 1/2 in. X 20. AGS coils are the same copper nickel alloy tubing as used in our pre-made lines. AGS is the industry leader in the automotive aftermarket for NiCopp brake, fuel, and transmission lines. This NiCopp kit is an economical solution for shops that want to build their own lines, custom lengths or non-standard applications. Use to fabricate 3/16 Domestic, European, Japanese, British, and adapter brake lines. AGS NiCopp is a nickel-copper alloy brake tubing that meets SAE Standard J1047 and ISO 4038; meeting all international and U.S. requirements for brake tubing. This alloy is approximately 9.2 Percent nickel, 1.4 Percent iron, 0.8 Percent manganese, and 88.6 Percent copper. Under the UNS system, this alloy is designated as UNS C70600. NiCopp is not only much more corrosion resistant than steel, but easier to bend and form and has the strength and structural integrity of steel lines. Nickel-copper, commonly referred to as 90-10 copper, has been used on several European vehicle brake systems since the 1970's, including: Volvo, Audi, Porsche, and Aston Martin. NiCopp has been used on hydraulic/fluid transfer systems on vehicles where steel lines and tubing are commonly used, including brake, fuel and transmission systems. NiCopp is considered the super-premium alternative for brake lines and should be considered where harsh environments are a factor, where the longest life-span for lines is required, and/or where direct OEM replacement is desired. NiCopp Does Not Rust or Corrode-DOT Approved for Hydraulic Brake Systems-Bends 58 Percent Easier than Steel Tubing and is available in 25, 50, and 100 ft lengths-Finished Lines Available for Domestic and Import. NiCopp lines and tubing meet the following specifications: SAEJ1047, ISO 4038, SAEJ1650, DIN 74234, BS2871.
