OKO is injected into a tubeless tyre, via the valve stem, BEFORE a puncture occurs. OKO remains liquid inside the tyre, giving protection against punctures that may occur in the tread area. When a puncture happens, air pressure forces OKO into the hole, aided by strong centrifugal force generated by the rotating tyre. OKO immediately forms a strong airtight seal that STOPS any tyre deflation. So OKO seals the hole as you drive and can be regarded as a permanent seal. It is 1.6 x stronger than a vulcanised puncture repair

OKO effectively seals holes as they occur, over and over again. The products are designed and engineered by the OKO Research team in conjunction with a leading Rubber Technology Research Institute. The whole OKO company, including production and administration, is certified under ISO 9001 for Quality and ISO 14001 for Environmental good practice. The company has also been assessed and warranted to be Carbon Negative – it removes more carbon than it generates, largely due to its ability to lengthen the life of vehicle tyres. OKO has been tested by various armed forces and major vehicle producers. Approved by JCB; Massey Ferguson; Manitou; and fitted to the wheels of disabled vehicles by various manufacturers / distributors. OKO has been used by the British Army since 1988; various S.E.A.T.O & N.A.T.O. forces; plus the United Nations Procurement Agencies. OKO has been operational with allied forces in areas of conflict like Iraq, Afghanistan. Tried and tested in the most hazardous situations.
