Sure; disconnecting the spring lock couplers is not too difficult, once tou see how the process works.
First, spray some WD40 or similiar light penetrating oil into each coupler; this makes the disassembly process easier. Then if possible rotate the 2 components in opposite directions, twisting them to make sure they are as free as possible.
Now, take the tool and place it around teh smaller part of the line, so that the lip on the tool is facing the open side of the coupling. Press the tool into the coupling untill it is completely seated; this is expanding the round garter spring inside the coupling that holds it together.
While holding the tool in place, gently pull the coupling apart using a twisting motion if possible.
When reassembling this type of coupler, always install new O-rings of the proper type, new garter springs, and lubricate the O-rings with mineral based refrigeration oil before snapping it back together.
