Ok thank you! Sharkbite also makes Pex A https://www.lowes.com/pd/SharkBite-1-2-in-x-100-ft-Blue-PEX-A-Expansion-Pipe/5001460723Heatlink was new to me, and made in Canada. Licensed by Uponor. https://www.heatlink.com/content/heatlink-signs-licensing-agreement-uponor
PEX A can be used with expansion fittings, so the ID is bigger than those using the crimp or clamp fittings.
Apollo makes PEX A for some of its pipe.
Sharkbite PEX is PEX B, and use crimp or clamp fittings.
https://www.hammerpedia.com/oregon-frost-line/ says the frost line in Eugene is 12 inches. So officially you should probably blow out your pipe. How about putting it a tad lower?
I don't have any of the pex tools so are there any other fittings I can use besides sharkbite push connect?
I could dig a little lower but pipe will be insulated as well. It only gets down to 25 dgerees F for a couple hours a few days a year.
