Daisy-chaining gas manifolds

[BrewSomeMore]

Ok, I want to connect two gas manifolds together. Do I need a left threaded coupler or right threaded? Not many "threads" out there on this subject. Many thanks.

Left handed if it is regulator to regulator.

If truly coupling one manifold to another manifold, both ends will use right-hand threads, most likely 1/4" NPT.
I've not seen a manifold using left-hand threading...

Cheers!

Ok, they are low pressure connections so they are right threaded whereas high pressure connections are left threaded. Awesome, makes sense now. Thanks!
