Are “push to connect” same thing as a shark bite?

I was shopping for some compression fitting supply line valves and noticed the overwhelming majority of supply line valves are of the “push to connect” flavor…presumably catering to DIYers at the big orange.

I’m just curious, is that the same thing basically as a sharkbite with the back facing teeth or does push to connect work differently?

Same thing. I will use them sometimes, but like most plumbers, we're a little wary of them.
If I can solder I do, If I can use expansion PEX, I do.
I prefer compression stops on copper over push to connect.

I find it interesting with how sharkbite came out only in 2004 but it seems like maybe they don't have a patent on the exact concept since others are basically making the same thing?

I mean the old garden hose quick connect is essentially the same concept but instead of barbs it uses balls and thus requires a compatible male piece.

Watts makes a similarly functioned fitting, but it's a plastic body versus brass. There may be others out there. Patents and copyrights don't last forever, and making a better mousetrap is human nature to explore, especially if he can make money off it.

Qest angle stops worked with the same principle. A compression backwards toothed washer held those onto a copper stubout.
