A is the dimension letter in Dixon's catalogue drawing, in millimetres. Dixon's catalogues give different B and C figures for these liners, so only A is shown. No dimensions are published for the 1/2" and 3/4" liners under these part numbers.
Selecting the right option
Confirm the union is a DIN style before ordering, because DIN, SMS and RJT unions are not interchangeable. Choose the size from the tube OD you are welding to and the DN size of the equipment. The liner works with a DIN round slotted nut, a weld male and a DIN seal, which Dixon lists separately.
