German DIN (ULM/ULOS - VHM-VHOS)

German DIN (Deutsche Industrial Norme)

Popular couplings are German DIN (Deutsche Industrial Norme).  A coupling refered to as "Metric" usually means a DIN coupling.

DIN 24 ํ Cone
The DIN 24 ํ cone male will mate with any of the females shown.

The male has a 24 ํ seat, straight metric threads and a recessed counterbore which matches the tube O.D. of the coupling used with it.  The mating female is a 24 ํ cone with O-ring, a metric tube fitting or a universal 24 ํ and 60 ํ cone.

There is a light and heavy series DIN coupling.  Proper identification is made by mearuring both the thread size and the tube O.D. (The heavy series has a smaller tube O.D. but a thicker wall section than the light).

When measuring the flare angle with the seat angle gauge, use the 12 ํ gauge.  (The seat angle gauge measures the angle for the connector centerline)
