Anyone have an issue with a weld-less valve kit not tightening enough? I finally got around to trying mine out on a 5g pot I have and no matter what I try I cannot get the gap between the coupling and the hex nipple to be even close to providing a seal. I am using the gasket included with the kit and I think I'm doing it all correctly (only 3 parts) but I'm left with probably 1/8" gap. The fitting is slo loose it free wobbles. Since the coupling is round I can only hold it with my hand to tighten but I can't get it to go any further in due to it's taper. The teflon tape help a bit but the gap is way too big still. I wonder if this is even possible with pots that are on the thin side.
