Four way CO2 Manifold via William’s Brewing. Each of the four runs has a ball valve with an integrated check valve.
Check Valves. The check valve ensures that liquid doesn’t backflow from one line to another. It’s not common for beer to backfeed up a line, but it is certainly possible.
Barb Fittings. Each of the four runs and the inlet feature 1/4″ barb fittings. Personally, I prefer barb fittings on CO2 lines as they don’t loosen over time. Even a small leak could mean an emptied CO2 tank.
Aluminium Body. This manifold features an aluminum body. One end has a 1/4″ NPT to 1/4″ barb installed for hooking up to your regulator. The opposite end has a 1/4″ NPT plug installed. That plug can be removed and another brass valve or part can be installed… Q87, D16, or D69.
As of this posting, the four way is selling for $29.99. My rule of thumb for a good deal on these is anything below $10 per trunk. This one figures to $7.50 per trunk. Check William’s Brewing for up to the minute price and availability.
