Hillhead regulars Air-Seal Products, the tyre sealant specialists, will be showcasing their complete range of premier tyre sealants, which prevent punctures up to 1¼in (30mm) and stop all rim bead and other slow air leaks. The company’s sealants are widely used around the world in large heavy plant, including trucks, HGVs and loading shovels, helping to improve operational efficiency by reducing costly downtime. One treatment costs no more than the full cost of one tyre repair and lasts the legal life of the tyre. Last year, Air-Seal Products launched their new environmentally friendly tyre sealant using propylene instead of ethylene glycol. It is the same product that has been helping companies save money on puncture costs and downtime for almost two decades. Air-Seal’s eco-friendly products are based on water-washable components with no glues or gums, which means they are easy to install and quick to remove using water.
