Techna-Fit RX7 brake lines are made using teflon hose lines. The teflon hose line has an extruded teflon core, with an outer stainless steel braided wire covering. The chrome or zinc plated steel fittings are then permanently crimped on each end. All Techna-Fit hose lines have a PVC cover, which gives added protection from flying debris; it also gives some abrasion protection from the line rubbing on suspension parts, in extreme braking conditions, with full compression (most movement of line).
One advantage is that Techna-Fit RX7 brake lines reduce volumetric expansion. Over time and under continuous use, OEM rubber lines can swell and expand, exposing the driver to brake fade. The rubber cover is also vulnerable to attacks from the ozone layer (rubber deteriorates and causes failure). In extreme applications (auto x, racing, hard driving) rubber hoses might be susceptible to debris, thus causing failure.
Stainless steel RX7 brake lines provide some added protection from these issues. All Techna-Fit's factory assembled RX7 Brake line kits are backed by their lifetime warranty.
