This is a handy and reliable Presta to Schrader adapter. The problem with the thread on adapters sold at bike shops is that they don't work well with a Schrader air chuck (as used with a compressor).
Note: This video is old and as you know the bike accessories market is constantly changing so instead of linking to a specific pump head as I mentioned in the video what I recommend you do is get your pump head FIRST and determine the size of the tank valve you will need (1/8" NPT or 1/4" NPT).
