Frequently asked questions
What is DIN 11851?
DIN 11851 is a German standard for threaded pipe couplings in the food industry, often called dairy coupling. The male side has external threads and connects to a female part with a nut and gasket.
What do DN50 and DN40 mean?
DN stands for nominal diameter, i.e. the size of the coupling. The adapter steps down from the larger DN50 to the smaller DN40.
Do I need a gasket?
Yes, both sides are sealed with a gasket. EPDM gaskets for DN50 and DN40 are sold separately.
