Hi guys. I have a Dacor D20 in mint condition that I would like to get into the water. What bothers me is the special swivel coupling port that connects to the octopus. I am referring to piece 169 in the schematics attached. I would simply like to plug that port and use the regular 3/8 for connecting LP hoses.
The thing is that it does not seem to be a standard thread, it has a larger diameter than the HP 7/16 and a slightly smaller (and different thread) from the LP 1/2 that some high flow second stages have.
Anyone knows the specs for the thread. The outer diameter of the connector is 11.9 mm (0.47 inches) and it looks like 24 TPI thread.
Thanks for any clues

Jordi
