Ok I have been searching a LONG while to try and find the right pipe fitting parts in order to build the amp but I cant find a crucial part (mostly because I dont know its name or whether it exists at all).
Here is the picture of the Part I am looking for:

Does anyone have any ideas on what's the name of that sort of fitting/connector?
In the picture I showed which ends of the pipe I definately need to be open, but I am not so sure for the other 3 endings. I guess they can also be open and then I will just find a way to close them
SO please if you are any good at this pipe stuff plz post below the name of that sorta fitting/connector or anything very similar
