DIN 3852 form a Chart

Date:Jun 01, 2019

The male DIN 3852 form A & B couplings will mate with the female DIN coupling.


The male and female form 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.


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