OKO Off-Road Tyre Sealant is the world's leading agricultural and construction tyre sealant, trusted by farmers, contractors, and fleet operators worldwide for over 45 years. The water-based, non-corrosive, non-hazardous formula instantly seals tread punctures up to 12mm in diameter as the wheel rotates, without stopping the vehicle. It extends tyre life by up to 20%, remains active for the full legal life of the tyre, and will not dry out, separate, or corrode rims.
The 25L drum is the professional-grade bulk format for agricultural estates, construction contractors, and fleet operators. Requires the OKO Metallic Application Pump (sold separately as OK024) for valve-stem installation.
Suitable For
Tractors, harvesters, loaders, forklifts, skid steers, quad bikes, golf carts, mobility scooters, wheelbarrows, and other slow-moving off-road and agricultural vehicles. Works in both tubeless and inner-tube tyres. Available at PartsForMachines with UK mainland delivery in 2–4 working days.
How to Apply
Apply through the valve stem using an OKO Injector (150ml syringe) or OKO Application Pump for 25L drums. The pump operates against tyre pressures up to 60psi/4.1 bar. Always apply to new or freshly fitted tyres. Drive 3–5km after installation to distribute the sealant evenly around the inner tread.
