I've tried several different options, but none fit well enough to prevent water/dust ingress. Others seem to have had similar problems, because these now exist... ARB Fitting Air Coupler Pacifier (ACP-ARB). They are spendy, but Joey makes top notch stuff.
Well, that sure looks like what I'm looking for. Right now I have duct tape over the chuck. I'll give one a try.
I'm surprised they take something special since it's a standard fitting. I've actually thought about taking a fitting and filling it with metal (solder?) and the sticking that in there. This is a great business opportunity for someone with a 3D printer.
