Which type of quick disconnect couplers to use?

Most if not all of the o-rings can be replaced using a pick. (looks like a round pointed screwdriver and real small.) All of the couplers that I have used, just un-screw to replace.

Thanks Jerry!
I will have a look see at the coupling next time I am out at the compound.
