OKO X-Treme MTB Inner Tube Sealant OKO X-Treme MTB Inner Tube Sealant

OKO X-Treme sealant uses a combination of synthetic latex and quick sealant mixed fibres to seal holes and slits in inner tubes up to 7mm in size.

The trouble with MTB tyres and inner tubes is that you need to run higher tyre pressures to avoid snakebite punctures, and higher tyre pressure means less grip. X-Treme MTB Sealant is the gold standard, you can run low pressures and still be protected from pinch punctures and snakebites without having to worry about burping your tyres.

Tubeless tyres have been around longer than most people think, they've been around on motor vehicles since the mid-fifties and the first effective tyre liquid tyre sealant was developed by UK-based OKO way back in 1978. For motorbikers, quad riders, long-distance lorry drivers and fleet managers the world over OKO is the go-to brand for protecting their tyres and keeping them on the road (or off-road). OKO is the number one tyre sealant brand in the heavy off-road market. If you run 'heavy-plant', tippers, 30-tonne quarry lorries with tyres costing 10k+ a corner then you trust OKO to keep running smoothly. With the proven ability to seal holes in big tyres up to 20mm in size with their thickest formulation, we'd trust them as well. In fact, that's exactly why we've teamed up with OKO. They're the tyre sealant experts.

  • Synthetic latex, no ammonia, non-allergic formula

    Like OKO Puncture Free X-Treme is also perfect for full UST wheel/tyre tubeless set-ups in the case of those who will be putting their bikes through extreme tests. Some lucky people with an excellent seal between their bead and rim use it in tubeless conversions (But we recommend you use OKO Magic Milk if you are using tubeless ready tyres).
