We Were Born in the Mud
Since 1978, we have been quietly making tyre sealant history—from the fields of rural Britain to the mines, motorways, and backroads of the world. What began as a clever fix for farmers has become a global force, keeping vehicles moving and wheels turning in the harshest conditions on Earth.
Made in Britain. Proven Everywhere.
OKO started life helping farmers stay in the field when time, weather and harvests wouldn’t wait. From those early days, we’ve always believed in making things that last—and work when it really matters. Our first bottles were mixed by hand. Today, they’re made in our UK facility, engineered to stand up to brutal conditions across every kind of terrain.
Wherever there’s a tyre that can’t afford to stop—we’re already there.
Every OKO blend is carefully crafted to match what you drive, where you drive, and what you’re up against—whether that’s hauling stone in 60-tonne dumpers or tackling the Alps on two wheels.
Thicker fibres, finer flow rates, tuned performance by temperature and tyre pressure. We get properly into the detail, so you don’t have to.

Seal it Once. Trust it Always.
Once OKO goes in, it stays alert. Sitting quietly inside your tyre, it reacts in an instant when trouble strikes—sealing the hole from the inside out before you even notice you had one. It’s not magic. It’s the force of physics, fibre tech and forty-plus years of field testing.
It’s the safety net you’ll never see—but always count on.
Saving Rubber. Cutting Waste. Carbon Negative.
Yes, we’re tough on punctures—but we’re gentle on the planet. Independent testing by Intertek confirms that using OKO reduces tyre waste and slashes carbon emissions by 22%. In fact, we’re proudly carbon negative—doing more good than harm, every time you fit us in.
Less waste. Fewer replacements. A tyre that lasts its full life. Now that’s real sustainability.
If it rolls, we’re ready.
From wheelbarrows to 18-wheelers, mountain bikes to monster dumpers - OKO has a tyre sealant blend built for your wheels. No drama, no delays. Just lasting peace of mind.
