I have a Swimquip DES 60 filter and I need a couple union adapters, but it seems that particular part is now obsolete? Any suggestions on where I might could find this part? The mfg code for the part is U111-208P. Attached is a pic with my filter details. My filter is currently connected to my push/pull valve using a flexible rubber coupling with clamps, but looking for a more permanent solution that can stand a little higher pressure when running my hot tub.
