My xspc kit came with G1/4 1/2" barbs and 3/8" ID tubing. I am planning on buying new tubing but in the color I want they only have 1/2" ID 3/4" OD tubing. Is it safe to use this tubing? The inside diameter is slightly bigger so obviously it will be easier to get on or off but is it safe? Or should I also buy G1/4″ to 1/2″ ID, 3/4″ OD compression fitting?
