The 1/4 to 1/8 adapter I picked up at the local hardware store, but, it leaks. It does not screw in far enough to make a contact with the seal. It will hold air, until the hose gets pushed in to its own fitting. For some reason, the adapter works fine on the 1/4 inch end of the Paasche hose.
The ideal solution would be a quick disconnect to go from whatever the thread is on the Paasche airbrush, to the blue hose. You can see, the compressor came with the female end of a Q.D.
Is there an ideal solution?
