When it comes to braided lines, Mishimoto offers a substantial variety of line and fitting options to ensure we have what you need for your project. Our PTFE-lined braided hoses provide substantial pressure and heat tolerances and are applicable for any automotive fluid without fear of line breakdown or degradation. PTFE lines utilize a specialized fitting, which seals using a compression ferrule, otherwise known as an olive insert. Because of the sealing method, these ferrules are single-use and must be replaced if they are removed after being torqued in position. In addition, we recognize that our customers often alter lines during projects, which is why we are offering a Braided Line Replacement Ferrule Pack.Mishimoto braided line ferrules are constructed from 6061 aluminum and are precision machined to exact tolerances. Offered in various -AN sizes, each pack includes 5 ferrules for multiple line adjustments or alterations. As with all our products, this ferrule pack includes our Mishimoto Lifetime Warranty.
