Slime Tube Sealant 473 ml provides instant flat tyre repair for inner tubes. Using patented Fibro-Seal™ technology, it locates and seals punctures up to 1/8” (3 mm) the moment they occur. Ideal for emergency use on bicycles, strollers, wheelbarrows, dirt bikes, and more. Air pressure forces the sealant into the puncture, forming a flexible and long-lasting plug. Non-toxic, non-corrosive, non-flammable, and water soluble – safe for both the user and the environment.
