Why does the description not show the size lines for in and out this unit will fit?

Fittings Size (1/4" TEE fittings)In case you need a bigger size fitting 3/8" for example we carry it ,you can search the following item B00TG08TQM H2o4u

What t fittings do I need to put this inline of my 3/4” pex? I’m assuming a few different fittings.

I am sort of going from memory, but I bought the white, I think teflon, fittings that are readily available at big box stores like Home Depot and Lowes. I believe the fitting provided is 1/4" so you need a pex fitting that fits the size of you pex pipe, but the "T" piece needs a 1/4" to take the one provided. I don't remember any particular difficulties, but in fact I was attaching to 3/8 white plastic tubing, so I needed a different "T" piece from the one you require. Its all a matter of finding the right "T" piece. I took a quick look, and the pex fittings are all compression fittings, so you might have to put a plastic loop with a t piece in the middle to take this device. Lots of ways to skin a cat.

How long are the cables? And is it for 1/4" ID RO line? Your missing the basics in the description

On the unit I purchased, the cables are approximately 45" long. It includes two "T" fittings for 1/4" RO/DI lines.

is this available with 1/2'' x 1/2'' x 1/4'' tee fitting? i need the probes to go to 1/2'' tubing

You can purchase 1/2 x 1/2 x 1/4 push-in fitting tees to replace the ones that come with it. I'm doing the same thing with a DI system for my detailing business.
