you could have tried the yellow teflon tape (for gas systems) or the liquid teflon dope. i just wrapped the white tape many times on EVERY male thread and hold pressure for a week solid.
There's what i was looking for. It's already done, so it's definetly permanent. Which means when I add another manifold for a couple more taps it will have to be attached to my 1/4 barb and hose to another 1/4 barb to the new manifold instead of a threaded coupler. Oh well
