Puncture protection for equipment that suffers the harshest off-road terrain.

‘Badass Tire Sealant’ – OKO Extra Heavy Duty in action
OKO Mining Xtra Heavy Duty is an essential aid to operators of vehicles that suffer the very harshest off-road terrain.
Fitting tires with solid polyurethane fill is one solution but it carries a heavy weight penalty, is very expensive and adversely affects the ride, as well as placing a strain on axles.
In most cases, extra heavy-duty OKO Mining can work as well as solid fill, at a fraction of the cost and with a minimal weight penalty. It seals holes of more than 20mm in diameter in tubeless tires. That is why it is the natural choice for mines, quarries, waste management plants, and rough construction sites.
Norilsk Nickel, the world’s biggest nickel mining group and one of the biggest all-round mining corporations, has tested and officially approved OKO Mining for use in its vehicles after extensive summer and winter testing (down to -52 degrees C).
In underground Chilean mines, tires that normally last only 5 months had their life extended to 7 months by the use of OKO Mining. This is due to its beneficial effects upon tire porosity, tire cooling and conditioning of the rubber.
Britain’s biggest housebuilder specifies only OKO Mining, for use on all its construction sites, following a competitive assessment of other tire sealants.
A Canadian forestry truck operating on harsh trails, fitted with tire temperature sensors, recorded a 11.5% average reduction in temperatures on its OKO-fitted tires compared to matched non-OKO tires. Heat is the greatest cause of premature tire wear.
OKO Mining is primarily designed for use off the highway. It can be used on road for slow-moving on/off road trucks and service vehicles, and is often used in countries with bad road surfaces.
New 25 liter (6.6 Gallons) purple drum for easy identification: easy to use, 32% larger/better value than 5 US gallon pails and you do not have a messy lid to remove.
Sold separately (a one-time purchase): NEW adjustable heavy-duty all-alloy pump, which delivers 8.5 ounces (250ml) per stroke for rapid and accurate filling through the valve stem, and works against pressure of up to 60 psi/4.21 bar. (Not to be compared with competitive pumps that you have to assemble, are plastic or rust-prone steel, deliver smaller doses, are not adjustable and do not handle such high pressures). Because OKO is water-soluble, the pump washes clean for repeated use, and if the tire is removed from the rim in the future both the tire and the wheel can be hosed clean. Anti-corrosion agents prevent any damage to either.
Many users of very large mining tires pour the sealant directly into the tire well (either in the full 25-liter quantity or via decanted 5-liter jugs) having mounted one tire bead on the rim: then they simply seal up the second bead.
Precise calculations depend on the tire size and type but typically OKO can be fitted to all 4 large industrial tires for much less than the cost of replacing one tire, even using a remold.
Mining Xtra-Heavy Duty – An essential aid for vehicles and equipment that suffer from harsh off-road terrain. For Off-The-Road (OTR) tires dealing with bad conditions or over 25-inch rims.
Off Road – A versatile, all-purpose sealant, good for any OTR tire. You’ll be glad you fitted the original and best off-road tire sealant and tire life extender.
