Hello, another possibility, but not with peacock model, (peacok is different than next model, the oprv hole is close from the body , there are not enough distance from the body to place a splitter), is using a splitter with an octo downstream valve. Like this, the octo downstream valve is also the oprv.
For the eary Snarks, with the peacock top box, I make an adapter based on the very rare Nemrod accessory that replaces the second stage plug. This one can't be used with a pillar tank valve, so I also make an adapter that replaces the OPRV.
On all snark, that I owned the lp oprv port are in 3/8
My Snark IIIs and Silvers have OPV ports that are M10x1.0. 3/8 x 24 is very close, but threads are slightly coarser and the diameter is slightly smaller at 9.45mm (10mm male end on fitting measures at 9.86mm). A 3/8 x 24 fitting screws into mine, but it is very loose. Are you positive yours is 3/8"?
Hello Phil, Thanks for the information, I really think that it was 3/8, I am gone check , when I come back home , with a thread tool. When I screw the splitter I do not fell resistance, that is why I thought that it was 3/8. About the HP port 7/16??? Edit 13/09/2023🤦🤦🤦🤦🤦🤦 correction HP seems to be 3/8

I am not positive what the HP port threads are, but probably they are imperial b/c I think they were made to accept a standard hose. The LP cover adapter made by Nemrod had a female 3/8 x 24 port for standard LP hoses.
