proven puncture protection


What is OKO

OKO prides itself as being the world’s first and leading manufacturer of advanced anti-puncture tyre sealants available. Now established for over 41 years, its accumulated knowledge, global sales, technical know-how and production experience has made it the world’s leader and no.1 choice for proven puncture protection.

OKO is an environmentally safe solution that comprises of specially treated materials of the highest grade, that have been specially formulated to perform and function in the most extreme conditions and harshest of environments. OKO can help deal with air loss and puncture problems of a tyre by providing a permanent seal to any hole or leakage in the tread and shoulder area.

How does it work

OKO is injected into the tyre BEFORE a puncture occurs and once installed, the viscous liquid remains in a pool at the base of the tyre. Given the motion of a revolving tyre, the centrifugal forces distribute OKO around the inner circumference providing a protective layer and coating against any punctures or leakages that may occur. When the tyre is punctured, air pressure forces OKO into the hole and compresses to form a strong, instantaneous and permanent airtight seal. OKO stays inside the tyre, ready to seal further holes and leakages as and when they occur, on a multiple basis.

In a sealed environment, OKO will always remain as a stable solution and will not disintegrate or precipitate. Its coolant additive significantly enhances the absorption of heat, lowering the temperature of the hull, which can help increase the working life of a tyre.
