Speed-Flex Line 3 AN Female Swivel Both Ends Hose Size 3 Length 12.. Our factory assembled hoses are made from the same SPEED-FLEX stainless steel braid protected hose of extruded PTFE that is the world standard of the racing industry for flexible brake, clutch and instrument hoses. Hoses are assembled with Earl''s SPEED-FLEX crimp or swaged permanently installed hose ends. Each hose is pressure tested to 4,000 psi.. We have independent test lab reports on file showing that prototype assemblies exceeded D.O.T. recommendations in all categories. The only continuing test program however, is a 4000 P.S.I. hydrostatic pressure test of every hose assembly that we make. We do not claim that any individual hose assembly is certifiable to D.O.T. standards, and we therefore must advise you that.
