Adding a Schrader Valve to a Homebrew Keg

Adding a Schrader Style Valve to a Homebrew Keg

This was really just a matter of putting the right fittings together.  Pictured: Milton (S-684-4) 1/4″ MNPT Male Tank Valve – Anderson Metals Brass Pipe Fitting, Coupling, 1/4″ x 1/4″ Female Pipe – LASCO 17-6783 1/4-Inch Female Flare by 1/4-Inch Male Pipe Thread Brass Adapter

A quick check to make sure all of this fit together

Everything tightened down with teflon tape

This assembly is a tank/Schrader style valve to a 1/4″ x 1/4″ female to female coupling to a 1/4″ NPT to 1/4″ flare fitting.  All that to say, I have this threaded onto a ball lock QD here, but it could just as easily thread into an MFL pin lock QD.

Installed and pressurized.  This may give you a hint as to what the the related post will be about, but… maybe not.

Assembly Components

The parts and pieces I used, all via Amazon:

Important: Make sure every component in your setup is rated for the amount of pressure you decide to use.

Make sure the components you use are compatible and rated for your intended application.  Contact manufacturer with questions about suitability or a specific application.  Always read and follow manufacturer directions.

    I’ve done this. It’s very useful for pressure testing empty kegs without wasting CO2. Use an air compressor (or bicycle pump for a good workout) to inflate the keg, just like a car tire. Then spray StarSan or soapy water around the fittings and lid gasket to check for leaks.

    Mine uses a 1/4″ FPT to barb adapter to connect the Schraeder valve to a bit of air tube, then to a barbed ball lock disconnect. I believe that would be a cheaper build than this.
