The same tried and tested formula has been manufactured for the past 25 years  and is unique, it is the only fibre free sealant on the market. (Tyre sealants evolved with formulas which included chopped fibres, these products tend to dry out after a puncture is sealed and the tyre will deflate after a few days, Linseal technology is completely fibre free and tyres that are sealed in contrast to fibre sealants stay inflated without going down.)

The sealant remains active for the life of the tyre, permanently sealing hundreds of holes caused by puncturing objects of up to 10mm in diameter. In tests for the British Military, over 30 large punctures were sealed in a tyre and the vehicle was still fully operational many months later.
