OKO Truck & Bus is a concentrated HGV tyre sealant designed for On Road use in the tubeless tyres of Heavy Trucks, Semi-Trailers, Coaches & Buses, and other on-road vehicles over 5 tonnes that may travel at extended high speeds.

It prevents punctures and stops deflations happening as you drive.

OKO seals the hole in the tread area the moment the puncture happens.

OKO On Road Truck & Bus tyre sealant has been formulated to last longer in fast moving hotter tyres. It copes with the additional speed and heat and reduces the temperature inside the tyre.

Should last 100,000 to 140,000 km/ 60,000 to 90,000 miles before needing to be topped up (depending on usage, road quality and nature of the tyre).

Deals with loss of air and eliminates the puncture problem by providing a permanent seal to any hole made in the tread area caused by puncturing objects with a diameter of up to 8 mm.

OKO stays inside the tyre, ready to seal further holes as they occur.

25 litre drum is sold with a NEW heavy-duty all-alloy, high-pressure pump that is rinsed out after each use and is a one-time purchase. Unlike some others, it comes fully-assembled and ready to use.

Whereas some other sealants come in pails with messy removable tops, these secure drums have a screw top that replaces easily to protect the product until the next use.
