They are high temp unions and there are different ones, My type pump uses a 1.5 inch thread and 2 inch union like this
CMP 1.5 in. MIP x 2 in. PVC Hi-Temp Union 21063-160-000
some have a 2 inch thread and 2 inch union like this
CMP 2 in. MIP x 2 in. PVC Hi-Temp Union 21063-200-000
and others have 1.5 x 1.5
CMP 1.5 in. MIP x 1.5 in. PVC Hi-Temp Union 21063-150-000

the 1.5 inch to 2 inch can be used on skimmers, and through wall connections like I did :) when you screw them on make sure the go all the way to the rubber O-ring to make a good seal :)

Hope this helps :)

Thank you for taking the time to answer my question. Got a sec for another one? Am I going to have to cut the liner to use these or will the just plug into the hole already there?

you will have to cut the liner, the easiest way I have found is a soldering iron on high... mark your circle with a pen and cut/melt slowly... works great :)

here is my install post #93 New above ground oval 18x33 install

you will also need these




good luck and have fun :)
