Here you can see the completed threads done by the machine.† Taper BSP thread to fit into the 1Ē Worchester ball valve.† The Swagelok fitting has a straight thread and I wasn't sure whether to use a straight or taper thread, so threaded both ends of the bar, one taper, one straight.† Iíve since found out from Swagelok that there is a copper gasket that I need to seal the straight thread at the base.† I feel this should have been included with the fitting, but anyway, Iíve just ordered 2 of those and I will fit the straight thread.† Copper gasket part number CU-8-RG-2.
