The way my gas cock is oriented behind my range prevents me from installing a test gauge on it. So I figured I'd put the test gauge on a flex hose and attach the flex hose to the gas cock. This setup is not holding air long enough (>3 psi for >1/2 hour) regardless of how I tighten the flare nuts on the flex hose--kinda tight or very tight. Leak detector bubbles ever so slightly on the flares when I have 15 psi on there. I've tried two brand new flex hoses and they both seem to leak at the flares.
When I plug the gascock and set the test gauge up in the basement on the supply end of my new line, it holds air indefinitely. So all the black pipe joints and any place pipe threads are involved seems to be fine.
I imagine people don't often pressure test through a flex hose so I think these things leak more than people realize. Is there an alternative to the commonly available flex hoses with flares? I suppose the flares are there to make it easy to tighten without the hose spinning but something involving pipe threads ONLY seems like it would seal much better.
