The Deutsches Institut Normung standards DIN 11864-1 and 11853-1 are specifically concerned with aseptic screw joints for connecting piping in food processing plants. A DIN 11864-1 Form A fitting uses an O-ring, which is embedded in the male threaded part, while Form B uses a square-section gasket. The addition of a female plain piece and a round lock nut makes up the complete DIN fitting.
