If you are only going to do a couple of connections, you might consider a pex "pocket crimper". They are used in conjunction with a set of vice-grips & require multiple steps w/ adjustments to the vice-grip's tension to complete a crimp. Their main advantages are: price (<$30), versatility (they can do crimps on 1/4", 1/2" & 3/4" fittings) & work space requirements (since they use vice grips, they often fit in areas too confined for traditional 1 stroke crimpers). You can google to find on-line sources or just pick them up at a local Lowes or Home Depot.
I opted for a $80 Kobalt set from Lowes. It was a multi-head, 1 stroke tool that works on all pex sizes w/compression rings. I also ended up also getting the clamp removal tool - it allows re-use of removed fittings. Both tools performed as advertised & were much quicker than using PVC and waiting for solvent welding to cure...
A different option is the use of the cinch clamp tool. It can also be used on all sizes, but uses the cinch-clamp bands instead of compression rings. They run about from about half to the same cost as multi-head tools & the bands they use end up with a small tab sticking out ...
