Propane quick connect for 27 PSI camp stove

We're thinking of using a quick connect between the 27 PSI regulator (near the tank on our teardrop) and our Cook Partner camp stove. We've ordered this

but I think we may have made a mistake. Seems these are for "low pressure" grills, although I've seen comments on Amazon suggesting folks sometimes use it before the regulator, which would be something like 145 PSI at nominal temperatures.
I've also seen high pressure quick connects, which seems like it might be what we should use.
So I guess the main question is, will this work safely at 27 PSI? Where is the dividing line between "low pressure" and "high pressure" in the propane grilling/cooking industry?
As always, thanks for your comments!
