OTK Tyre Bead Screw with O-rings & Long Tyre Valve Single Wheel Pack

Wheel bead screws with O-rings (OTK finger grip style) are specialized M5 safety screws designed to prevent kart tires from breaking their bead or rotating on the rim under heavy cornering loads. The knurled "finger grip" head allows kart racers to spin them in quickly by hand, while the rubber O-ring creates an airtight seal against the wheel barrel to prevent pressure loss. 

The Long TR413 Tubeless Valve is designed to provide an excellent airtight seal on tubeless rims. Ideal for karts, cars, and light vehicles, it ensures durability, safety, and easy installation. Made from high-quality materials resistant to high pressure and temperature, it's perfect for both professional and enthusiast use.
