Can this go over a hub?

Answers

You would need to measure the hub. This coupling is intended to connect (or repair) a PVC pipe with an INSIDE diameter of 4 inches. The outside diameter of this pipe is 4.5", so if your hub is in the 4-3/8 to 4-1/2 inch range, you should be able to fit it on securely enough.

Innacurate Description
Its clealry marked as 4”. It is very much 5”. Luckily I live close to store but still a huge annoyance and waste of my time. I don’t often need parts like this. Is this some sort of twisted “normal” industry standard of measurement? Like a 2x4 NOT actually being 2x4?

These worked exactly the way I needed them to. I was worried that they’d be too tight when I slid them on so that I’d have a rough time of it, but they were just slightly larger and slid onto my old drain pipe without much effort. Highly recommended. Sure beats smelly glue and primer!
