The OSRAM TYREseal 450 is a liquid tyre sealant that uses particle gel technology to seal tyre punctures of up to 6 mm in diameter. After application, drivers can continue their journey for up to 200 km to reach a garage or tyre dealer, or to have the tyre permanently repaired rather than replaced. The full sealing process takes under 10 minutes and requires no tools or jacks, making it a practical roadside solution.

The product's valve passage technology means the valve insert does not need to be removed during application. Its formula is designed to be compatible with vehicle tyre pressure monitoring systems (TPMS), unlike foam sealants. It serves as a replacement for manufacturer-fitted OE sealant sets and can replace those that have exceeded their 5-year service life. It is also available as part of the OSRAM TYREseal KIT, which includes a compressor and storage bag.
