Non standard gas line for Grainfather Pressure Transfer Kit.

[Vetal]

I bought a Grainfather Conical Fermenter with a Pressure Transfer Kit. I was going to use this to transfer the NEIPA I have going to my keg. I just found out that the gas line that comes with the Grainfather Pressure Transfer kit is not an SAE standard size. I believe its 5mm ID. The closest SAE equivalent would be 3/16th (4.762 mm). If I get a 3/16th inch barb and somehow convert this to a 5/16th inch standard gas line - would that work? I am thinking that there would still be a gap between the hose and the barb (approx 0.2 mm)... not exactly air tight seal. Any ideas? Thanks.

always use a barb larger than the tubing. A little dip in boiling water and it will stretch over.

Would a 1/4 in barb suffice? I ordered a 3/8 in barb and it is way too big.

1/4 in barb worked perfectly.
