Jay, I believe your correct. The drawings and one picture show the tabs on the main chamber opening for a locking ring locking means, and those don't show the bevel that would be needed for locking with the two-part locking means shown as well in other pictures. I can see a design in my head for the flange on the main chamber that could have both types lock onto it. The NATO locking ring flange would work on it as it normally would, but the two part design would likely need to be a bit different to allow it to stay clear of the locking tabs on the main chamber that are used for the locking ring type. So unless the design could take both standard types of locking means I don't know what advantage it would have.
Is the two-part locking means also a NATO standard configuration, or just the locking ring type.

The two-part clamping ring interfaces with beveled surfaces so that when the tighter it is drawn together, the more pressure is put on the flat mating surfaces. R/Jay

So does
that mean they can be locked by both a rotating ring type, as well as a
two-part coupling flange, as it appears this DART unit can? Are
all the outer mating parts of the two-part coupling flange beveled so they
increase the pressure on the seal further as the two clam shells are brought
closer together? |
