Why kink-repairing air coils
Standard nylon coiled air lines usually fail by kinking when they're stretched, tangled or disconnected. Once a standard line is kinked it no longer meets DOT spec and has to be replaced. Reflexallen Intelli-Flex tubing is made to flex, kink, fold and stretch and keep working, from winter cold to summer heat.
For mechanics: Sold as a red and blue pair. Pick the length, coil diameter and lead length from the table to match the reach from the back of cab to the trailer. Molded in-line leads and non-corrosive cable guards cut chafing, whip and coil sag.
For fleet buyers: A standard nylon coil that kinks or creases no longer meets DOT spec and has to be replaced. Intelli-Flex tubing can kink, crease, fold and stretch and still pass DOT requirements, and its black tubing resists UV, abrasion and chemicals.
