Tyre Sealant Liquid For Tubeless Tyres. Tubeless sealant is a liquid designed to plug small holes in a tyre’s casing, thus preventing punctures. Our liquid tire sealant works to seal punctures up to 1/4″ (6.5 mm) quickly.
Although they are advertised as “prevent and repair,” these tire sealants are best added before use. Sealant is a liquid with some type of fibers inside (every manufacturer has their own secret sauce) that when you puncture, almost immediately find the hole and seals it from the inside of the tire so you can. After installation, when the tyre rotates puncturefix pro forms a layer inside the tyre and when the tyre encounters a puncture, the air pressure in the tyre forces puncturefix pro to seal the wound.
