NPT to QD hose setup

[That Petrock Emotion]

I just bought a booster where the drive gas feeds in though a standard QD (same gauge as an inflator hose / drysuit hose). I want to use a compressor instead of air from cylinders. I have a three chamber water and oil filter that I would run between compressor and booster. The outflow port from the filter is a 1/2" National Pipe Taper (NPT) female. I need to get a hose which goes from a male 1/2" NPT to the above-mentioned standard QD. Help appreciated!

You can make an adapter very easily however you may want to consider changing the the drive gas feed into something other than an LPI and use a standard QC (Industrial or Automotive) compressor fitting. If your booster is a mini (small variety) then it should be fine but these can restrict flow of drive gas for larger boosters. I really only use LPI on my smaller Haskell mini.

You can buy 1/2" NPT to 1/4" NPT bushing/adapter and then get a 1/4" NPT to 3/8" F to use an LPI hose

Interesting, thanks!

That BC nipple is going to be a massive constriction on your drive gas flow. Which booster is this? It may be very unhappy running on a massively upsized 1/2" hose (depending on the compressor output)
