Specialized Airlock Tube & Tire Sealant
8oz Bottle | Flat Prevention | For Tubes with Removable Valve Cores
The Specialized Airlock Tube & Tire Sealant is an easy and effective way to reduce flats and keep you riding longer. Designed to coat the inside of your bicycle tube, Airlock continuously seals small punctures and slow leaks before they become ride-ending flats.
Its advanced, completely homogeneous formula stays evenly distributed inside the tube without separating or puddling, providing reliable, long-lasting protection. The convenient 8oz bottle contains enough sealant to fill two standard bicycle tubes and includes a valve core remover and application hose for quick, mess-free installation.
