Linseal is spread over the inside of a tyre tread area as the wheel revolves, ready to seal puncture after puncture. When the puncture occurs, the escaping air pressure forces Linseal into the hole immediately forming a strong airtight seal.inseal is the revolutionary liquid puncture preventative. Linseal is designed to remain fluid inside a pneumatic tyre or innertube. Linseal will seal a hole in the tread area of a tyre instantaneously when applied BEFORE a puncture occurs.
