This tool can remove the valve core from Schrader-style valve stems. These are commonly found on mountain bikes, car tires, HVAC, and water rocket launchers.

As this is a plastic tool, it cannot match the strength of a machined metal tool. Depending on the tightness of your valve, it may not work, or may break down after one or two uses. 

Version 1 (orange in pic) is the original; single-ended, very functional.

Version 1.1 (blue in pic) is slightly shorter for sturdiness and double-ended.

Try both and let me know what works better!
