Slime tube sealant seeks out and instantly seals tread area punctures up to 1/8 in (3 mm) using fibro-seal technology. Install in your bicycles, dirt bikes, wheelbarrows, riding mowers and more and enjoy two years of continuous flat tire protection. Slime tube sealant prevents and repairs flat tires caused by puncturing objects up to 1/8 in (3 mm) in diameter. Slime works repeatedly to repair new and existing punctures and is guaranteed to perform for up to two years. The inner tube formulation should not be used in a tubeless tire. Slime sealants are designed to treat tread area punctures only and should not be used to repair sidewall punctures, snake bites, rim spoke punctures or gashes from metal or glass.
