Radiator relocate kit question- need help from others with them

So i just received my Rubberdown Customs Rad Relocate kit for my 13 Outty 1K. Top notch quality, very nicely manufactured and very sturdy. Only one part of the kit has me a little uneasy which is why im here asking. It came with the plastic 1" connectors to attach the different coolant hoses together. My question is this, how long have other members had these on their quads with no issues? I just feel a little uneasy with them, but im sure they’ll be fine. I was thinking about picking up some brass ones instead, but figured I’d ask before i dropped the $$$ on them. I know my truck has the composite within the coolant system but that seems to be a bit heavier and thick, what came with the kit has me questioning it.

Figured id ask! Thanks for the help guys and gals, ill get up a pic of my kit once installed!
