Adding additional Premium Secondary C02 Reg's onto a Micro Matic 1163

[Highjnx]

Should have bought the 4-way secondary, and now I'm wanting to add an additional unit onto the 3-way system I installed. I've inquired directly with MM, and was given the number of my local Rep who never returned my call in Seattle. So I put this out there - what is the correct connection nipple needed. The other three are chrome plated brass or stainless, and look similar to part # 1319069. However that part has Left Hand Threads, and the Secondary Reg's have RHT. MM lists a couple of brass options, but they wouldn't match the look of the original 3.

Any help is appreciated.

Cheers
