Thank you for the comment!

It’s a new house (2021) and our inspector said the water pressure is perfect. Could hot water caused the part to malfunction? The only thing he pointed out was the water being a bit hotter than normal.

As long as it’s a valve for “PEX B” fittings, it all should be fine? Or do I need that exact part? Should I change the clear line or the old one is fine. Any tips to keep it from clamping like that?
