The test caps are just called test caps. I don't know their purpose fOr plumbing. I got some for the ends of my pipes though, they look exactly like the removable cap liners that come inside body scrubs so they don't spill. The end caps are pipe line line ends. They go on the outside of the Pvc pipe and are therefore too big to push the soap out with. Coulda bought a smaller one. IV been using drinking glasses turns upside down to push soap out of my Pringles molds but I don't know how it will work with PVC.
