Product No. - OKO001 The OKO Off Road product can be relied upon to seal tread-area holes with a diameter of up to 12mm (in tubeless tyresit can also be used in inner tubes, where smaller punctures can also be sealed). However, unlike some other companies, OKO does not over-claim on behalf of its products. In tests, OKO Off Road has shown that it can seal holes of up to 20mm in bigger tubeless tyres. Even if it cannot always achieve this, it will slow down deflation to allow the driver to bring the vehicle safely to rest. Off Road OKO is primarily designed for use off the highway. It can be used on the road for slower-moving on/off-road trucks and service vehicles, and is often used in countries with bad road surfaces; it is preferred to other sealants for use inside inner tubes. It is not for regular long-distance use on any surface over 80 km/hour, or 50 mph. Product No. - OKO072 This is an application pump which easily fits on to the threaded opening of our on and off road
