Yeh, but some tubes, like at the master, have special nuts, AKA 3/16 tube but larger than normal threadIs it not 3/16 line from MS to Prop?
We are talking about special as opposed to the standardized fittings that are normally on a "say" 3/16 OD tube as in the chart I posted. any thread other than those is not "standard." There is only one standard thread size for 3/16 tube and that is 3/8-24Soooo does anyone know what size that is? If it is not 1/2 or 9/16 with 3/16 tube then I am lost as to what is considered special?
