It all started with a British farmer, a leaking tractor tyre, and a question no one else had properly answered. That first OKO formula—born in the field and mixed with a practical, no-nonsense mindset—set the standard for what a tyre sealant should be: fast-acting, permanent, and built to last.

Over the decades, we’ve fine-tuned that core technology to handle everything from bicycles to military trucks. It’s the backbone of our range and the reason we now create bespoke sealants tailored to tyre weight, pressure, wall thickness, and the conditions you drive through—because one size never fits all.
