Advantages

Reinforced Metal Gasket
Features a sturdy 1.5mm thick steel ring around the valve hole. This prevents tearing under high pressure (tested to 150 PSI) and ensures a tight, secure seal for the valve stem, drastically reducing the risk of air leaks.
Precision Valve Stem Hole
The hole is die-cut to an exact 10mm diameter to snugly fit standard truck valve stems. Combined with the metal eyelet, it guarantees a secure fit, protects the tube from damage at this stress point, and maintains optimal air retention.
Heavier & Thicker Construction
We use a high-grade, durable rubber compound that is 6.0 mm thick and weighs approximately 5.2 kg, significantly more than standard tapes. This massive build provides an ultimate barrier, resisting pinch flats, rim abrasion, and penetration from sharp debris.
