In theory no. In practice a good solder joint is proven to last 50+ years* while that exact design of adapter has been in widespread use for maybe a decade. *longer, actually, but other parts of the copper pipe will fail by friction before the solder joint does. Answer from bunjay on reddit.com

r/HomeImprovement on Reddit: Connecting copper pipe to pex - is there longevity and reliability differences between shark bite push adapters vs. female sweat adapters?
August 23, 2019 - The pex fitting for the copper was made of solid brass, and my torch did not get hot enough to make a weld that I felt confident with. Since I only had one connection to make, I ended up with a nut/bolt compression fitting that went onto the copper, and I screwed on the male pex connection. It worked, and I think it cost about $5. ... Sharkbite adapters great are great but they do fail.

My primary concern was how the existing copper, PEX and SharkBite would work together but more so how it would be accepted by potential buyers and inspectors. Answered as okay, TY. I'm moving forward now with PEX and SharkBite asap. Home Depot has most material in stock for what we need.
