  • 25 litre drum & durable pump

OKO Mining Xtra Heavy Duty is an essential aid to operators of vehicles that suffer the very harshest off-road terrain. Fitting tyres 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 minimal weight penalty. It seals holes of more than 20mm in diameter. 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, tyres 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 tyre porosity, tyre 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 tyre sealants.


A Canadian forestry truck operating on harsh trails, fitted with tyre temperature sensors, recorded a 15% average reduction in temperatures on its OKO-fitted tyres compared to matched non-OKO tyres. Heat is the greatest cause of premature tyre wear.


OKO Mining is primarily designed for use off the highway. It can be used on road for slow-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.

The black 25 litre drum is used in combination with a durable aluminium-barrelled pump (sold separately), which delivers 200ml per downward stroke for rapid and accurate filling through the valve stem. Our specially-designed pump works against pressure, so you can inject OKO into tyres containing up to 45 psi/ 3.1 BAR.

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 large industrial tyres for much less than the cost of replacing one tyre, even using a remould.

Benefits

  • 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
  • Seals the hole in the tread area the moment the puncture happens
  • Designed for use in the harshest off-road environments
  • Lasts the legal life of the tyre
  • Deals with loss of air and provides a permanent seal to any hole in the tread area caused by puncturing objects with a diameter of 20mm+ in large tyres
