OKO Puncture Free for Bikes


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 tyre
Suitable for all bike types
Ideal for tubes or full UST tubeless conversions


   OKO Puncture Free is a water-based liquid that is able to work on both tubed and full UST tubeless tyres.

   It gives peace of mind and lasting security for the tyre’s life, with a dose of 60-100ml per tyre in mainstream bikes, depending on size.

   An all-purpose product for commuting to mountain biking, 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’ tyres, use a rim strip plus OKO Magic Milk)

   250 ml bottle deals with one large bike with some to spare: for 26” MTB tyres it is now just 100ml per tyre, 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 tyre. Keep one in your backpack to make a bicycle puncture repair; with a tyre pump or gas bottle you can reinflate and ride away after many a puncture.

   Simple fitting, using the valve core remover and filling tube supplied in every bottle cap: or use an OKO Tyre 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 tyres rapidly. It uses the unique OKO Bike drum pump with adjustable dosage, plus Schrader and Presta screw fittings.
