Buy Shrader Valve tubes and accessories, the most common valve found on bikes and cars.

Wikipedia:

The Schrader valve, invented by August Schrader in 1891^[1] consists of a valve stem into which a valve core is threaded, and is used on virtually all automobile tires and wider rimmed bicycle tires. The valve core is a poppet valve assisted by a spring. Schrader valves are also used on the fuel rail of some direct fuel injection engines and on some refrigeration and air conditioning systems, in a fitting larger than those used on tires, to allow servicing, including recharging with refrigerant. In addition, Schrader valves are sometimes used on irrigation systems to provide a place to temporarily attach a portable pressure gauge and they are often found on the buoyancy compensator hose of SCUBA regulator systems, allowing the user to remove the hose and attach the hose while in use. Schrader valves are used in bladder pressure tanks to introduce air when the air cushion needs topping up.
