The Austrian wine thread differs from the international wine thread, which has a metallic conical seal, in that a flat seal is used as a seal and a separate sealing ring is required.
As a characteristic feature, the nut is equipped with two round studs.
The Austrian wine thread is available in the following nominal widths:
4/4" (1")
5/4" (1 1/4") and
6/4" (1 1/2")
