Pump hose upgrade
You could possibly replace the compressor’s hose (or cut it and replace the end part of it) with the Twin-head adapter hose kit from Topeak (www.wiggle.co.uk/topeak-twinhead-kit/). It comes with a selection of adaptors for common hose-fitting threads, plus an all-else-fails option for cutting and connecting to the orginal hose. The ‘Twin-head’ gives you the option of connecting to Schrader or Presta with equal facility. I have one of these on a floor pump. It’s been reliable.
