Need Help with RODI System Fitting

[FluctuatingCO2]

Hello, everyone, this will be my first post. I have many years of freshwater experience, but I am working toward my first reef tank. I am building a new house and I need help finding a fitting to connect my RODI system. I had the plumber leave a 1/2" PEX line for me to connect to for feed water, as well as a nice P-Trap for the waste water (picture attached). The RODI system and controller will go on the wall, with water-change station underneath. I would appreciate it if someone can help me find a fitting to convert from 1/2" PEX to 1/4" polyethylene RO tubing. A fitting with a shutoff valve would be a bonus. Thanks in advance.

Thank you, that might work, though I did not provide enough detail in my initial post. The rest of the PEX work in the house is crimped, so I think the plumber would rather stick with crimped connections.
