   OKO Magic Milk™ is a step forward for latex-based free-flowing liquid tyre sealants. It can be used with ‘tubeless ready’ or full UST tubeless tyres (for maximum puncture proofing on UST we recommend Puncture Free Bike or X-Treme)

   It is super-light, with a dose of 30-80ml per tyre in most sports to mountain bikes, depending on size.

Used and recommended by Habitat Mountainbike Team in World Cup MTB and Cross Country Mens & Womens events.

   250 ml bottle deals with two regular mountain bikes, or four racing bikes: for 26” MTB tyres it is just 60 ml per tyre. NOW new 500ml and 1 litre sizes, by popular demand

   Simple Schrader fitting, using the valve core remover and filling tube supplied in every bottle cap: or use an OKO Tyre Sealant Injector (especially when using removable-core Presta valves) for easy, accurate measuring.


Latex-based for sealing wheel/tyre bead imperfections
In practice, the lightest sealant you can use
Longer effective life than competitors – usually 6-12 months before you need to top up
Advanced synthetic latex formula – no allergies: will not rot tyres or damage wheels
Contains corrosion inhibitors
Washes off with water
Non Hazardous


   Non Corrosive: Non Flammable: Non Hazardous (not excluded from air shipments unlike some ammonia-containing products). Washes out of the tyre if required.

   NO ADVERSE AFFECT UPON TYRES OR RIMS (contains anti-corrosion agents).

   WORKS WITH TUBELESS READY and FULL UST TUBELESS WHEELS/TYRES, with Schräder or removable-type Presta valves. (if you have non-removable Presta valve cores, pour Magic Milk into tyre well then mount tyre onto rim).

   For ‘tubeless ready’ tyres on standard rims, always use a rubber rim strip plus OKO Magic Milk™. Shake the tyre/wheel combination vigorously from side to side at each point to force the sealant into the little gaps between bead and rim, and into the tiny holes in the porous tubeless ready tyre sidewalls. Also spin the tyre on the wheel for a prolonged period. Follow tyre and wheel manufacturer instructions.

   (For tyres with inner tubes, use OKO Puncture Free Bike or OKO X-Treme)

   Colour: White. Free-flowing. Low Odour (no nasty ammonia smell).
