German DIN 3852 Couplings Type A & B (Parallel Threads)
The male DIN 3852 Type A & B couplings will mate with the female DIN coupling shown below.

The male and female type A & B couplings have straight threads. Sheet 1 refers to straight metric threads, and Sheet 2 refers to straight Whitworth threads. The seal occurs when the ring seal (Type A) or the face seal (Type B) mates with the face of the female port.

There are two series of DIN 3852 Type A & B couplings, the light (L) and the heavy (S) series.
