Puncture Safe is a liquid gel product, easily installed in minutes through the tyre valve providing your vehicles with permanent protection against punctures (up to 9 mm HGV). IT IS NOT JUST A TYRE SEALANT! Developed in the United States, Puncture Safe conforms to stringent, British, American and European safety standards and has a 36 year unblemished track record for keeping transport moving. Puncture Safe lasts the life of the tyre and can be washed away when the tyre requires replacing. The Puncture Safe treatment doesn't just repair punctures as they happen; it also delivers further benefits. Puncture Safe helps control under inflation (the number one tyre killer) by creating a sealed air chamber within the tyre which helps improve fuel economy by up to 10%, extends tyre life by up to 40%, helps prevent blow outs and most importantly, keeps your vehicles on the road.
