Bike users told us that there was a gap in the market. Many riders have discovered the need for a bike tire sealant, but conventional latex-based bike sealants dry out rapidly and need to be replaced.
After years of development and testing, OKO introduced a ground-breaking range of bicycle tire sealant products. Worldwide testing in all temperatures and terrain confirms that OKO out-performs all other products.
STANDARD
OKO Puncture Free (all-purpose) and OKO X-Treme (for off-road use) are now lighter and smoother than ever, and represent an advance in puncture sealing performance compared to any competitor. They are both perfect for tubes and for full UST tubeless conversions. They last the life of the tire.
- The Best all-purpose puncture preventer
- Now lighter than ever
- Now seals holes up to 4 mm
- Works on multiple punctures
- Lasts the life of the tire
- Suitable for all bike types
- Ideal for tubes or full UST tubeless conversions
CHARACTERISTICS
OKO Puncture Free Bike is a water-based liquid that is able to work on both tubed and full UST tubeless tires. It gives peace of mind and lasting security for the tire’s life, with a dose of 60-100ml per tire in mainstream bikes, depending on size. An all-purpose product for commuting to mountain biking (perfect for peace of mind on your e-bike), it is ideal to use when converting to full UST tubeless, where you need a sealant that can deal with serious punctures. Many other bike sealants are just too weak to get the job done. (For ‘tubeless ready’ tires, use a rim strip plus OKO Magic Milk).
BENEFITS:
- Not latex-based
- Lasts the life of the tire
- Combats larger punctures
- Seals multiple holes
- Contains corrosion inhibitors
- Water-soluble
- Non Hazardous
SPECIFICATIONS
| Non Corrosive: Non Flammable: Non Hazardous (not excluded from air shipments unlike some ammonia-containing products). Washes out of the tire if required. |
| NO ADVERSE AFFECT UPON TIRES OR RIMS (contains anti-corrosion agents). |
| WORKS WITH INNER TUBES and FULL UST TUBELESS WHEELS/TIRES, with Schräder or removable-type Presta valves.(For ‘Tubeless Ready’ tires, use a rubber rim strip and OKO Magic Milk, which is the best sealant to seal the bead/rim gaps). |
| Colour: Blue. Viscous. Low Odour. |

For an even easier way of obtaining the OKO Puncture Free benefit, especially if you prefer Presta valves, try OKO Self-Sealing Inner Tubes. For maximum accuracy, for easier use with removable Presta valves, and for a host of workshop uses, use the OKO Tire Sealant Injector.
FEATURES
250 ml bottle deals with one large bike with some to spare: for 26” MTB tires it is now just 100ml per tire, up to 20% less weight than any recognised competitor. It’s a really economical way of ensuring peace of mind, for a fraction of the cost of replacing just one tire. Keep one in your backpack to make a bicycle puncture repair; with a tire pump or gas bottle you can reinflate and ride away after many a puncture.
Simple fitting, using the valve core remover and Schräder valve-sized filling tube supplied in every bottle cap: or use an OKO Tire Sealant Injector for easy, accurate measuring.
25 litre drum is ideal for retailer and team service workshops: the heavy-duty drum pump is a one-time purchase and can be rinsed out again and again for repeated use in filling tires rapidly. It uses the unique OKO Bike drum pump with adjustable dosage, plus Schräder and Presta screw fittings.
PRECAUTIONS
No risk and safety labels or warnings are required since this product is not classified as hazardous under current regulations. Normal safety precautions should be taken: wear gloves and protect eyes. Rinse product off any clothes that it may be spilled upon. Keep away from children. If swallowed, see a doctor.
X-TREME
OKO Puncture Free (all-purpose) and OKO X-Treme (for off-road use) are now lighter and smoother than ever, and represent an advance in puncture sealing performance compared to any competitor. They are both perfect for tubes and for full UST tubeless conversions. They last the life of the tire.

- Seals slits, snake bites and holes like no other product
- Now deals with slits and holes up to 7mm

CHARACTERISTICS
NEW FORMULA X-Treme is a genuine step forward in tire sealant performance – a real breakthrough product that fights bigger holes and even slits. Designed for the needs of off-road competitors and weekend riders, it is the difference between making it home and being left stranded by a ‘snake bite’/ pinch flat. It has been tested in the most demanding downhill, extreme and cross-country events and has been the difference between winners and losers. One 400 ml bottle will protect both a rider’s tires, with enough to spare. Like OKO Puncture Free, it is also perfect for full UST wheel/tire tubeless conversions in the case of those who will be putting their bikes through extreme tests. (Use OKO Magic Milk if you are using ‘tubeless ready’ tires).
BENEFITS:
- Not latex-based
- Lasts the life of the tire
- Combats larger punctures than any other sealant
- Seals multiple holes
- Contains corrosion inhibitors

It is super-light, with a dose of 30-80ml per tire in most sports to mountain bikes, depending on size. Magic Milk: the choice of leading World Cup contenders, Habitat Mountainbike Team. They use Magic Milk with Kenda tubeless-ready tires and Stan’s rims and find it “perfect” (Maarten Kemperman, Team Manager). Also used by top road race teams.
BENEFITS:
- Latex-based for sealing wheel/tire bead imperfections
- In practice, the lightest sealant you can use

- Advanced synthetic latex formula – will not rot tires or damage wheels and is safe for the many latex allergy sufferers
- Contains corrosion inhibitors and does NOT give off ammonia
- Washes off with water
- Non Hazardous
SPECIFICATIONS

| WORKS WITH TUBELESS READY and FULL UST TUBELESS WHEELS/TIRES, with Schräder or removable-type Presta valves. (if you have non-removable Presta valve cores, pour Magic Milk into tire well then mount tire onto rim). For ‘tubeless ready’ tires on standard rims, always use a rubber rim strip plus OKO Magic Milk. Shake the tire/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 tire sidewalls. Also spin the tire on the wheel for a prolonged period. Follow tire and wheel manufacturer instructions. |
