This is my first post to the forum and I will say up front I am not working on a plumbing project. However, the project that I am working on, I'm pretty sure is using a plumbing fitting. Can anyone tell me from the my photos if this is a plumbing fitting and if so, what is the name of it? I have scoured the standard box stores and have come up with nothing. The photos are for a device that picks up hockey pucks and stores them in a tube. I am just trying to figure out the black fitting and the rest I can fabricate out of PVC. Thanks in advance.
