Inline Regulator for… $6.99!

william's brewing inline regulatorKeg King Inline Regulator via William’s Brewing.  About: “This in line regulator features 1/4″ hose barbs, and can be adjusted with a flat head screwdriver. It can reduce incoming pressure from 150 PSI to 1 PSI. It is very handy to use when you want to use a single output C02 regulator in a draft system, but supply different kegs with different dispensing pressures. 4.75″ long with included brass hose barbs installed.”

This is basically an inline secondary regulator.  You still need a primary regulator attached to your CO2 tank.  The idea is, you set the primary to the highest pressure you will use (without exceeding specifications of any component of your system) and then use these regulators inline (one per line) to fine tune pressure and carbonation [See: Balancing Your Draft System].  As an example, you could set your primary to 25 PSI for faster force carbonation and set each line to a different pressure based on desired carbonation level.

I think this is brilliant, especially at the current price of $6.99.  Check site for current price and availability.


The inline regulator is adjusted by a screwdriver and does not have pressure markings or a gauge.  You could use something like this inline gauge, manually check pressures with something like this keg pressure tester, rig up something with a t-fitting or (my least favorite) use trial and error.

    “Alternate Use Idea: I don’t see any reason why you couldn’t reverse the intended direction of this and use it as an extremely inexpensive Spunding Valve.”

    I don’t think it works the way you think it does. A pressure regulator like this senses a downstream pressure. If the downstream pressure drops, the valve opens. When the system pressure is satisfied, it closes. The valve regulates a higher pressure down to a lower pressure.

    If you reverse the installed direction the valve will simply close off as the pressure in the fermentor rises, as it is only trying to maintain the downstream (now upstream) pressure above a minimum level. When that level is met, it will close.
