Does anyone have experience with C&S Unions? I purchased a used heat pump earlier this year and did not think to ask for the other half of the union thats attached to the pipe. I now have the male half of the union and the nut that screws on but not the slip on part of the female union. This is on a Pentair heat pump HP1200 so it's 2" plumbing. I am trying to figure out what union I need to buy to get the correct half I need. All thats on the union parts I have is C&S Plastics / Sylmar Calif. Is this typically what comes on the Pentair heat pumps? I hate to order the half union from Pentair and this not be the original union. I do not think I have enough pipe on the heat pump to cut off the union and install another one. Suggestions?
C&S Union or Pentair?

Is this the part you are looking for:
C & S Plastics | Union, 2"s x 2"s | CSU-199 | CSU199
You'll pay more, but you can get it in a Pentair bag:
473381 | Union
C & S Plastics | Union, 2"s x 2"s | CSU-199 | CSU199
You'll pay more, but you can get it in a Pentair bag:
473381 | Union
I guess my short answer is yes, thats what I am looking at. Do you think they are both made by C&S? That's what I am trying to figure out. I dont mind buying the entire union for that price but would like to use the threaded half thats already on the heat pump.

Just use the half that you don't currently have to connect up to the existing bits on the heater. I don't know if they are available except as a complete union, but the parts should be interchangeable.
I am also worried about the threads being different. The one on C&S website says it has special fine threads unlike others.

Go to Lowes/Home Depot (or your local hardware store) and get a 2" union and see if the thread fits. If not, take it back get the pentair part (or just order the pentair part).
The Lowes one is a thought.. I am not worried about the price at this point. I am wondering if C&S is the company that makes the unions for Pentair? I currently have the C&S on my heat pump, or half of it.... I am trying to determine if the Pentair is the same as the C&S or vise versa. Maybe either would work, I dont know? Wondering if C&S makes the union a little different for the ones that Pentair uses? Maybe I am over thinking it but I had issues with other unions when I re did my plumbing. Had to unions that looked the same but had different flanges and threads. Non had part numbers.
