Does anyone know of a source for a 1/4" FFL (Female Flare) swivel to 3/16" barb? We all use a 1/4" FFL to 1/4" barb for our liquid lines connection to the quick disconnect at the keg end but it's a real pain to insert a 1/4" barb in the 3/16" tubing especially if you're using thick wall tubing. You've got to insert the tubing into boiling water to make that happen. I can find a 3/16" barbed tailpiece that connects to the shank end but I have not been able to find a 1/4" flare swivel that has a 3/16" barb. McMaster-Carr doesn't. The one Midwest supplies says is 3/16" barb is actually 1/4". ChiCompany has a 5/32" but that's too small. Anyone gotten lucky here?
