OKO was the original effective tyre sealant when launched in the UK in 1978, has always been made in the UK, and thanks to a programme of continuous development and range extension since then, it remains the best.
It continues to be manufactured (with ISO 9001 and ISO 14001 certification for OKO’s entire operation) from cutting-edge ingredients sourced from leading innovators in chemical development. Imitation may be the sincerest form of flattery, and in the present day, there are many Tyre Sealant competitors to OKO. Viewing their websites and literature, many of their statistics, facts and statements stem from the original OKO data and web site.
