I can not change tools without letting all the air out of the compressor. Reason is I have a hook on my left hand. If I had a shut off value on the out let I wouldn't have to empty the air each time I change tools.

I think quick connects will work for you, as long as you are talking nail guns or impact guns etc..

you can hold the tools between you legs and use your good hand to work the fitting

That is how i did it when i cut my finger off

good luck

I would offer same advice quick disconnects on all my air tools

Using the right fitting from the compressor will help you. Starting from compressor attach a female fitting then attach the male fitting to the hose run about 4 mtrs of hose then attach a female fitting to the hose then attach a male to a regulator/water trap (the in hole) then attach a female fitting to the other side of the reg.(the out hole) then a male fitting to the rest of the hose and at the end of the hose attach a female fitting and then attach the male fitting to the tool. This setup will be a easy way of disconnecting and re-connecting hose's and tool to your compressor plus with fitting the reg./water trap your air tools will last longer. If your still not sure contact your nearest air tool specialist and they should be able to give you what you need and set your compressor up for you. Good luck!!!!!!!!!
