Waterbox connection to COR 15

[seasand23]

How the heck do you attach a Waterbox 18/24 flex pvc to a COR 15? It seems additional parts need purchased than what comes in the box. Specifically, the collar portion doesn't seem to fit my adapter. Either too small or too large. Pics would be helpful too :)

Can you post an image of the Waterbox flex PVC and the adapter you're trying to fit it to?

I figured it out. Glued a 1.25" conversion adapter to the top of the union and the top fit into the tube. Thanks for following up.
