1.5'' PVC Union thread size

[tevch]

I have an old 1.5'' male union and I am looking for a female part
However, all 1.5 unions I can find have different threads. What I have seems finer thread.

Any idea what is the model or the name for that thread?

What is that union connected to?

It is connected to Fafco solar heater. I got it used with the existing male union part, which seems to be DIY

Many pool manufacturers use proprietary union threads that are not interchangeable with anyone else. See if Falco sells unions.

Thank you. As I said the whole PVC connector was DIY by the previous owner. But yeah, I checked - Fafco doesn't sell unions.

Let’s see if @1poolman1 recognizes it.

Have never really paid attention to the thread-pitch on PVC parts, just know that "this" won't fit "that."
Also have never seen solar panels use unions. Why not just get a new union, and if the dimension is critical, a 1.5" pipe extender, cut the old off and use new. Seems it would beat looking for something to match.

Yeah, that is what I am gonna do after spending too much time looking for this weird thread pitch. This was just last hope. Thanks anyway.
