You mean a union? Not clear that solves the problem either.
If you glue up two separate halves of a union, without the union
being together, you may not get the two halves to be perfectly
square with each other. When you glue up the second half, they
may be out of alignment.

Yeah, union, couldn't think of the right word.

It might work in some cases, as PVC pipe has some flexibility. But I agree, slower glue would be a better solution.

What if you refrigerate the glue? Does that give you some time? It does with epoxy.
