The stiff extruded PTFE liner with tightly woven high-tensile stainless steel outer braid solves the brake pedal travel problem by eliminating line swell. This increases the firmness and feel of the brake pedal, which allows you to modulate brakes more efficiently. Compatible with alcohol, gas, E85, diesel, hydrocarbon fuels, nitromethane, mineral and synthetic lubricants, and high-density fuel additives.
In the mid-1960's, Earl's pioneered the use of the armored flex hose of extruded PTFE to solve the brake line expansion problem associated with the new disc brake systems. The stiffness of the PTFE liner combined with the tightly woven high tensile stainless steel outer braid solved the pedal travel problem. By eliminating the line swell it also dramatically increased the firmness and feel of the brake pedal which allowed drivers to modulate the brakes more efficiently. Improved abrasion resistance and increased temperature capacity are secondary advantages.
The PVC coating on some variants of Speed-Flex hose provides improved appearance and abrasion resistance as compared to the standard stainless braid. Although the coating color is new, the hose is Speed-Flex and has all the same features, benefits, and durability that customers have counted on for many years.
