This heavy-duty sealant comes in a suitably businesslike package.

It is an essential aid to operators of vehicles that suffer harsh off-road terrain.

The Off Road heavy-duty product can be relied upon to seal holes with a diameter of up to 12mm. 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.

Off Road OKO is primarily designed for use off the highway. It can be used on road for slower-moving 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 use on any surface in excess of 80 km/hour, or 50 mph.


The green Off Road 25 litre drum is used in combination with a durable all-alloy pump, which delivers 250ml per stroke (against pressure of up to 60 psi/4.1 bar, so you do not need to deflate the tyre) for rapid and accurate filling through the valve stem.  Because OKO is water-soluble, the pump washes clean for repeated use, and if the tyre is removed from the rim in the future both the tyre and the wheel can be hosed clean.   Anti-corrosion agents prevent any damage to either.

Precise calculations depend on the tyre size and type but typically OKO can be fitted to all 4 agricultural or large industrial tyres for much less than the cost of replacing one tyre, even using a remould.


Punctures are one of the most common causes of costly downtime, and OKO can eliminate most of them

Can avoid the tyre damaging itself on the rim and having to be replaced
