  • Mild Steel -3 AN Brake Line Kit
    Mild Steel -3 AN Brake Line Kit
    (Part #6178560)
    x
                

    This brake line kit bridges the gap between our stainless steel -3 AN kit, and our steel inverted flare version. It includes a 25 foot roll of 3/16" steel brake line, four 18" stainless steel braided hoses and enough -3 AN fittings to plumb your brake lines. 

    Since we don't know what calipers and master cylinder you will be using, these fittings are sold separately.

    Stainless Steel Brake Line, 3/16 Inch

    Our 3/16" stainless steel tubing is made from 304 grade (rated at 6000 psi) which is double annealed to allow easy flaring.

    NOTE: This line is intended to be used in conjunction with 37 degree AN # 3 style fittings which make use of a single flare. Stainless steel line will not work with 45 degree double flare 3/8"-24 flare nuts. We strongly suggest that the 37 degree single flare (flaring tool # 910-89524) be used when flaring this line for the AN # 3 tube nuts and sleeves.
