500ml Motorcycle Tyre Sealant & Instant Repair (Linseal OKO): Linseal International Limited has developed the worlds first fiber and latex free tyre sealant. The sealant is a secret mixture of thixotropic compounds and recycled rubber. Following a year of rigorous testing the sealant has proved 100% successful in both tubed and tubeless tyres. The new sealant is much less viscous than it's predecessors making installation much simpler and quicker. 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.
