We supply the premier tyre sealant both to the UK market and overseas. Our Heavy Duty product will seal punctures up to 15mm in diameter and our Armour-Seal up to 30mm. Our water-based tyre sealant range have an indefinite shelf life and are non-reactive, meaning they will not react with the tyre rubber and do not polymerise, vulcanise or cure. Additionally Air-Seal Products tyre sealants will not separate and are also reusable. When removed from a worn tyre, they will be equally effective in another tyre. In fact our chemist have a sample that was removed from a road going vehicle that had accumulated over 300,000 miles – the life of three tyres and is still fully functional and could be used today.
