OKO Original Mining is classifed 'Non-Hazardous' and is safe for transporting by air, sea or land. It carries ISO 9001 (Quality), ISO 14001 (Environmental) and ISO45001 (Health & Safety) certifications - no other sealant company has as many approvals.

Whatever the lifespan of your tyres to date, expect OKO to extend it by at least 20%, even with no punctures. The sealant seals the tread, keeping the tyre cooler, more flexible, and at the right pressures.

For as long as the other tyres that have no punctures.

Yes - only a small amount of OKO is used in sealing each puncture, leaving plenty for the other tyres.

OKO Original Mining is not compatible with 'Direct' TPMS systems that use electronic sensor valves with narrow air passages. If the system uses sensors that are applied to the inner wheel rim, then the sealant can usually be applied.

Yes - the sealant forms a layer around the inner tyre tread. If any stray liquid has remained inside the valve, clear it with a stick so that the passage of air is not impeded. Always unscrew the valve core using a VCR (valve core remover) before applying OKO. Screw it back in after installation then reinflate the tyre to the recommended pressure. Note that mining and large construction vehicles often have large-bore valves and an adapter will be needed when using the drum pump.

OKO Original Mining can be used in any tubeless off road (OTR) tyre (tubes are weak and it is not possible to seal big punctures). It is most effective in tyres above 25 inches of wheel diameter. For the very largest, thickest tyres, of 50+ inches, where punctures are not common but tyre life is very short due to external damage, we recommend OKO LifeLong - it flows freely, cooling and conditioning tyres and protecting wheel rins from corrosion.
