Mini Keg Carbonation Cap / Pressure Relief Caps

These stainless steel caps are a great option for home brewers for carbonation & conditioning in our Mini Kegs.

These caps fit all of our mini kegs. They are a M35x1.5 thread (35mm thread T/D size 33.5 pitch 1.5)

Rather than needing a double ball lock spear for each keg you can use these.

The pressure release caps are great for those who want to naturally carbonate in the keg using dextrose etc without the need to worry about over priming. Should the pressure get too high in the keg (about 35 psi) the valve will release some to prevent any explosions or over carbonated beer (the kegs are rated to 100psi so it  would take a LOT of over priming to make one blow up)

The carbonation cap with ball lock post is great for those who prefer force carbonating using a CO2 regulator. Simply screw it into the keg, attach your gas line or mini regulator and set to the desired pressure.

Using a line splitter or a gas manifold you can carbonate multiple kegs simultaneously or have one with ball lock spear and be pouring from it while others with these caps carbonate.

  • Can you use this on the single ball lock connection ? = is there a 6mm barb under the cap ? The purpose is to quick foce carbonating in a i-kegger a small batch. Thank you.

    Hi David -
    Yes the single ball lock tops now come with a barb on the bottom - so you are all good to go (c:  YOu just need a bit of hose to connect the diffusion stone to the bottom of the cap.
