Here is what you need:
WATTS A-663 ADAPTER
I did this to my outdoor shower. I then added a
GILMOUR SHUT OFF VALVE. You'll want to add the shut off valve so you can keep any leftover water in the hose from draining out into your storage area.
I have all my water hoses, filter, etc fitted with
GILMOUR QD's - so I added the female QD after the shut off valve. Now, I can quickly snap on whatever accessory or hose I want to my outdoor shower.
The one I use most often is a hose fitting similar to
THIS ONE. The spray jet setting - and hot water - makes for cleaning the dutch oven a VERY simple task.
Hope this helps.
