> Relying on an o-ring

Another category is Shark Bite, a simple push-on tech that is almost homeowner proof. All you need for many jobs is a cutter, some sandpaper, and the fitting: no pro tools, no torch. There are tight joist spaces the new copper crimper won't fit and overhead soldering is fraught, which you can sharkbite in 2 minutes.

Back to O-rings, I do wonder about the lifetime of the seals in there though.

Depend on size and material of the o-ring. A o-ring is a flexible material that under pressure will bend in order to fit a space. Under high pressure the material might intrude out slowly, if you repeatably bend it it might snap, and as with many flexible materials it may go brittle and crack if exposed to changes in temperature or moisture.
