Review on Milton S 684 4 MNPT Male Valve: Ensuring Optimal Performance and Durability by William Turner

This little adapter solved the first world problem I spent hours trying to solve on the internet. I bought a 12 volt compressor for our van so I can quickly inflate my bike tires (and car tires if needed). The compressor was perfect except that it only had a Schrader valve fitted at the end of the hose, not the usual 1/4" NPT fittings. Schrader/Presta adapters to my bike tire stats every time I needed to inflate a tire I see a way to connect a Presta cartridge to a 1/4" compressor hose. I was about to give up and return the compressor when I came across this wonderful 1/4 NPT Schrader adapter. It works great for what I need and with this adapter (plus a JACO Presta air chuck and some quick disconnects) I can use a 12v compressor to easily inflate tires with Presta valves.
