Abstract
Official abstract text for this publication.
A flare-type brake line assembly includes (a) a brake tube having a flare with a first sealing surface, (b) a brake component having a port with a second sealing surface and (c) a tube nut to secure the brake tube and brake component together. At least one of the two sealing surfaces is treated to increase the coefficient of friction between those surfaces. A related method is also disclosed.
First claim
Opening claim text (preview).
What is claimed: 1. A method of sealing a flare-type brake line assembly including (a) a brake tube having a flare with a first sealing surface, (b) a brake component having a port with a second sealing surface and (c) a tube nut, comprising: treating at least one sealing surface of said first sealing surface and said second sealing surface to provide a first coefficient of friction between said brake tube and said brake component greater than a second coefficient of friction between said tube nut and said brake tube by (a) applying a material selected from a group of materials consisting of a paint, an adhesive, or a glue, to said at least one sealing surface or (b) roughening at least one sealing surface of said first sealing surface and said second sealing surface to increase said first coefficient of friction above said second coefficient of friction while maintaining sufficient sealing robustness between said brake tube and said brake component to prevent high pressure brake fluid from leaking between said first sealing surface and said second sealing surface when the first sealing surface is against the second sealing surface. 2. The method of claim 1 further including securing said brake tube to said brake component by tightening said tube nut in threaded engagement with said brake component. 3. The method of claim 1 including applying a paint to at least one sealing surface of said first sealing surface and said second sealing surface in order to increase said coefficient of friction between said first sealing surface and said second sealing surface. 4. The method of claim 1 including applying an adhesive to at least one sealing surface of said first sealing surface and said second sealing surface in order to increase said coefficient of friction between said first sealing surface and said second sealing surface. 5. The method of claim 1 including applying a glue to at least one sealing surface of said first sealing surface and said second sealing surface in order to increase said coefficient of friction between said first sealing surface and said second sealing surface. 6. The method of claim 1 , further including roughening said at least one sealing surface by a process selected from a group consisting of said acid etching, chemical etching, laser etching, knurling, sand blasting, and combinations thereof.
