Make sure you use male to male rotary fittings or you'll never get them to line up facing perfectly when you tighten them
EDIT : i suppose you could pad out the difference with an extra O ring here and there.
I got both, my worry with the male to male rotaries is the added height with them. Was looking to see if Bitspower has another way of connecting them together like the water tank connectors but doesn’t look like they do.
