I am removing a bathroom fixture that was attached to this cold water supply line:
I need to plug the pipe so it doesn't spray water when I turn it back on. Previously it had this fitting:
I tried this cap, but it leaked quite a bit.
I searched through many fittings at the hardware store, and finally ended up with this valve:
which worked (except when I put it on backwards, then it squirted water out, ack!).
It took 4 trips to the hardware store to arrive at this solution, and it's not really ideal, since I never want to turn it on. What would an ace plumber have done instead?

Jay, it looks like you have a typical RV compression fit PVC line there. Looking at your pics, I don't see any pipe threads on the end of the tubing. It is difficult, if not impossible to match a threaded fitting to this type of pipe. You might have to go to a RV supply with the pipe type(usually printed on the pipe) and purchase an end cap for that specific tubing. If you don't have a pex tool or compression plyers to install a collar, there may be a self sealing compression fitting much like a Shark Bite that can be installed with a wrench, or a simple glue on cap fitting. Be sure to remove any scored or damaged tubing end before trying to install a new fitting.
