Pentair UV Sterilizer Union HELP!

[BQ5]

I have an older Pentair UV Sterilizer model EU25-U that I bought used from facebook. Unfortunately, it make without the unions and I’ve been having trouble finding a solution to get this this plumbed onto my system. Looks like the part number I need is ZUNIONB15 but know one carries it anymore. Has anyone had a similar issue and found a good solution?

Have you tried reaching out to pentair directly? I've purchased replacement unions from them in the past.

Do you have the old female ends with the pvc pipes glued in if so you can try to cut the pipe flush and buy a honing tools to drill out the old pipe.
