OKO GelFor all tyre sizes

The OKO gel can be relied upon to seal holes with a diameter of up to 10mm. 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. Even if it cannot always achieve this, it will slow down deflation to allow the driver to bring the vehicle safely to rest.
