Manifolds allow you to have one CO2 tank with multiple lines. Each line can be turned off individually without affecting flow to other kegs. Each ball valve contains a check valve that ensures no beer or gas can flow between the two kegs. The barbs are all 5/16", standard for gas line in the beer industry.
We also have 3 way, 4 way, and 6 way Manifolds
3 Way $39.99
4 Way $49.99
6 Way $59.99
