For curing a puncture through to the tread, the air pressure from re-inflating forces OKO Puncture Free into the hole instantly forming a strong and permanent seal of any hole up to 7mm wide. Continued movement of the tyre forces the remaining liquid sealant around the tyre helping to maintain the exact tyre pressure for the legal tread lifetime of the tyre.


If you have more then one off-roader there is a 25 litre drum available for use by garages and fleet workshops, it comes with a heavy-duty aluminium shaft pump that doses 200ml per stroke, just rinse out after each use.
