I believe Oliver's only have 1/2" PEX, but I’m not assuming anything. I only carry 1/2" spare parts and pipe. I carry a SharkBite 90*, coupling, tee, cap. I also carry a PEX pipe cutter and a SharkBite fitting removal tool. A word of caution about SharkBite fittings in general, some of their fittings are reusable and others are single use, so pay attention to which you purchase. Although I have complete confidence in SharkBite fittings, I have never had one fail while in service. I have had installation failures of my own making. So read all documentation available and follow the methods outlined within and all should be good.
I do have PEX crimp rings and crimpers at home and they are very hard to use for repairs below decks. So I don’t have any problem leaving SharkBite fittings in service, that I installed in an emergency.
The last bit of advice that I have is, buy a reusable SharkBite PEX fitting and some PEX pipe and get busy practicing.
