ARNCO Flatproofing

Pumped into the tire through its valve stem, Arnco’s patented*, liquid polyurethane flatproofing polymer replaces all of the air and cures to a resilient, synthetic rubber core in 24 hours. It completely eliminates flats. It works in any tire with a sound casing. It works in the most adverse weather conditions; Arnco flatproofing has been tested to 70° F below zero by the University of Alaska. It works to keep your equipment working.

Arnco Flatproofing is available in three grades to meet your your particular load, ride and traction needs.

Flatproofing is achieved by replacing the air in any pneumatic tire with a patented liquid  polyurethane that is pumped into the tire through the valve stem.  The result is a resilient, synthetic rubber core that will never go flat.
