To use OKO sealant, simply inject the correct amount into the tyre through the valve stem using the OKO® Injector or OKO® Pump, which are specifically designed for OKO products. Follow the dosage instructions on the label according to tyre size. After application, re-inflate the tyre to the recommended pressure and drive for 3 to 5 km (2 to 3 miles) at a moderate speed to distribute the sealant evenly around the inner tread. The tyre is then protected and ready for use.

OKO works immediately after application. As soon as the vehicle is driven and the tyre rotates, the sealant spreads and coats the inner tread. If a puncture occurs, the internal air pressure forces the sealant into the hole, sealing it instantly—usually within a fraction of a second—without any delay.

Yes, OKO is safe for both you and the environment. It is classified as non-hazardous, non-flammable, and non-combustible under international regulations. OKO products are formulated to be environmentally friendly, and they contain corrosion inhibitors that are safe for metal components. While basic precautions should be followed—such as avoiding eye contact and not ingesting the product—OKO poses no serious health or environmental risks. Used tyres with OKO can also be disposed of through normal recycling channels.

OKO sealant lasts for the legal life of the tyre. For Off Road use, it remains effective until the tyre is worn out. For On Road vehicles, it can last between 100,000 km to 140,000 km (approximately 62,000 to 87,000 miles), depending on driving conditions and usage. It does not degrade, dry out, or separate over time—it stays in suspension, ready to seal punctures whenever they occur.

If OKO is inside the tyre, you can continue driving normally after a puncture. The sealant works instantly to seal the hole as it happens, preventing air loss. Unlike traditional run-flat situations that can damage the tyre, OKO helps preserve the tyre’s integrity, allowing you to drive for the full remaining life of the tyre—provided the puncture is within the sealant’s capabilities and the tyre structure is not compromised.

Yes, OKO is designed to seal multiple punctures over time. A single application can handle numerous holes in the tread area, as long as they are within the maximum size specified on the product label. It remains active inside the tyre, ready to seal each new puncture as it occurs.

OKO is compatible with external TPMS (Tyre Pressure Monitoring Systems) that measure pressure from outside the tyre. However, for internal TPMS sensors located inside the tyre cavity, the sealant may coat the sensor and interfere with accurate pressure readings. In such cases, OKO is not recommended unless the TPMS is external.

Yes, you can safely inflate your tyre after the sealant has been applied. OKO remains in the lower part of the tyre and does not travel up the valve stem. It will not block the valve or interfere with air flow, so you can pump up the tyre as normal.

OKO can be used in any pneumatic tyre, with specific formulations for different vehicle types and conditions. OKO Off-Road is ideal for agricultural, construction, and off-road machinery; OKO 4x4 & Van suits SUVs and commercial vans; OKO On-Road is designed for motorcycles; OKO Truck & Bus is for tubeless tyres on heavy trucks and buses; and OKO Mining is built for extreme industrial environments. While OKO works in both tubeless and inner tube tyres, tubeless is always recommended for optimal performance and durability.
