I picked up a 3-way manifold today, but didn't notice until I got home that the barbs on the manifold are probably 1/4" od and the red gas line that I have is 3/8" id. Am I going to be able to clam down tight enough with my Oetiker clams on the hose to get a good seal on the barb, or should I put a wrap or two of teflon tape around the barb, before I put the line on it? The only other line that the LHBS has is clear, thinner lines for party taps, but it would seat snugly on the barbs.
On a semi-related note, the one keg is now venting gas through the release valve, even when the pull ring is all the way down. Can I just keg lube the schyte out of the release poppet, or do I need to order a relacement?
