Our Ventrac authorized liquid tire protection and sealant that minimizes downtime and stops punctures in their tracks. The liquid formula inhibits algae growth with the addition of a pH buffer, as well as prevents rust and corrosion of the tire rim. The fibers in the liquid filler come together and bind at the point of puncture to stop the leak. It’s as simple as filling your tires and being ready for anything. ReSeal Aluminum Pump (Part No. 72.0042) required for use is sold separately.
