Why don FlexKORE™ hoses have additional support at the fittings, such urethane sleeve, similar to many other DOT hoses?
FlexKORE™ hose assemblies don’t require the use of additional external support at the fittings because the fittings and hose have been designed and manufactured as an assembly to comply with DOT test requirements without these aids. Typically, conventional two layer Teflon® braided stainless steel brake hose construction fails the “whip” portion of the DOT test criteria due to fraying of the wire braid at the fittings which can then lead to fitting pull-off, loss of pressure, etc.
