This picture is of a 1/4 inch PEX line from a reverse osmosis filter. This section is right before a remineralization cartridge. The water before that cartridge is fairly close to being distilled water. I was looking for any product that would allow me to create a t-tap with a valve so I could get distilled water whenever I want and also just easily turn the valve to have the reverse osmosis filter send water to my refrigerator instead.
When I repeatedly disconnect the 1/4" pex line from the cartridge and reconnect it, after a while the seal becomes ruined I found and I figured a t-tap would fix that issue. After looking online for quite a while I am unable to find something that would work.

Disconnecting and reconnecting those lines will stress the connections and cause them to fail.
It should be simple enough to tap into that 1/4" line using a tee connector as you suggest and then adding a 1/4 inch shutoff valve on the tapline. Following is a link to some inexpensive components but you can probably find them at your local hardware store as well.
