Switched from compression fittings to push-on ends after a freezing job in Minnesota cost me 4 hours of rework

I used to swear by compression fittings on outdoor runs, but after a -20 degree morning left me with three cracked connectors, I swapped to push-on ends with heat shrink. Has anyone else had compression fittings fail in extreme cold?

Whoa, wait - three cracked connectors in one morning? That's brutal, I've never seen more than one fail at a time even in the worst cold snaps. I mean I swapped to push-ons a few years back for outdoor stuff too, but mostly just for speed, not because I thought compressions were that fragile in freezing temps.

You said "mostly just for speed" - that's how I thought when I first switched. But after seeing a batch of compressions crack in one morning, I'm thinking the cold does mess with them more than people realize. Those plastic bodies get brittle fast below freezing.
