uhh.. silly question, but how do yall make sure your brass barbs are waterproofed on copper/plexi/polycarb tops?

the reason is that i have to put them on my rotor block (copper top)
then i goto do the same for my northbridge (polycarb) then i goto attach 2 barbs onto my plexi res..

so any input would b great
