Pex - minimum pipe length between fittings (with copper crimp rings) | Terry Love Plumbing Advice & Remodel DIY & Professional Forum

I’m installing some 1/2” pex and connected 2 fittings using copper rings with a very short piece of pex (just over 1-3/4” long).

After installed i googled and can find minimum length for when using expansion system would be 2” long for 1/2” pipe, but can’t find any details when using copper crimp rings.

Is there a minimum pipe length when using crimps?
Do i need to cut this out and connect with a longer piece of pipe?
