Air-Seal Products is a specialist UK-based company that provides a premier range of liquid-based mechanical tyre sealants designed to prevent punctures and maintain optimal tyre pressure. Established in 2000 and based in Wellington, Somerset, the company serves a wide variety of industries globally, including agriculture, construction, waste management, and heavy haulage. Their sealants are typically installed at the beginning of a tyre’s life and use a combination of aramid fibres (similar to those used in bulletproof vests) to instantly seal penetrations of up to 15mm in standard tyres and up to 30mm in heavy-duty earthmoving equipment.
The company’s “rather repair than replace” philosophy emphasizes significant cost savings by extending tyre life by up to 20% and improving fuel economy by up to 3%. Unlike many temporary emergency sealants, Air-Seal products are designed to last the entire legal life of the tyre, remain liquid without hardening, and can even be washed out with water for reuse in new tyres. This commitment to sustainability and operational efficiency has made them a key partner for large-scale fleet operators, such as the Royal Mail, as well as individual users of cars, 4x4s, and motorcycles looking for long-term puncture protection.
