QUOTE(Cap'n Krusty @ Oct 2 2008, 09:56 PM)  Please correct me if I'm wrong, but it appears to me that the ONLY difference between the currently available "racing" SS brake lines and the "DOT" lines is the sticker, certifying that the product so labeled has been tested in accordance with the DOT's specs and procedures. Costs money to do that, and the end user is gonna pick that up. If they can sell 'em to racers, that not-inconsiderable cost can be avoided, and their per-piece profit will be higher.

But to rephrase that, braided stainless teflon brake hose have passed TUV tests and are sold in Germany, just as the rubber hose sold there. That of course raises the question of whether they're also seeing these failures in braided lines.

There is a difference. The DOT 'whip' test described earlier stresses the joint between the hose and the swaged fitting, so hoses that are built to pass the DOT tests have a plastic collar extending a couple of inches up the hose from the fitting. This gives the hose a little support in the whip testing so it doesn't kink the hose where it goes into the swage. Non DOT hoses typically won't have that support collar, so they should certainly be a bit cheaper, and not only because they haven't gone through the expense of testing. If you're paying the same or more for non-DOT "racing" hoses then you're getting... uh... hosed. |
