The picture shows a broken wye on my Penn State 1 hp dust collector. I am thinking that I do not want a branch system but just want to connect one hose directly to the collector. I cannot figure what part I need to order and it looks like I need a part that has a screw that connects to the collector just like the wye I would be replacing. As you can see, over time, I never used the other branch and the cover on that branch was made of cheap plastic that split and I think I am losing a lot of suction power by having this branch system with an unused port so I like to connect my hose directly to the machine. According to my measurements the opening from the dust collector is 5 inches in diameter and the Branch ports are 4 inches in diameter to accommodate a 4 inch hose.
I cannot figure out from looking at Penn State industries or rockler what part I would need to order to replace the plastic wye.
