What Is OKO?

OKO Tire Sealants eliminate most puncture problems instantly, while you drive! OKO sealants are viscous fluids, designed to combat the costly inconvenience of suffering punctures. Unlike other products, OKO includes special corrosion inhibitors that inhibit rust on steel and aluminum rims. What’s more, our corrosion inhibitors normally last the life of the tire!

How Tire Sealant Works

OKO Tire Sealant is injected into your tubeless tire or inner tube via the valve stem before a puncture occurs. OKO remains in liquid form inside the tire, ready to provide lasting protection against punctures that may occur in the tread area. When a puncture occurs, air pressure forces your chosen sealant into the hole while the vehicle is moving, forming a permanent, airtight seal that instantly stops tire deflation. In short, OKO seals the hole as you drive!
