Some brewers choose to add pure oxygen in-line immediately after their wort chiller, through a 1/2" NPT 0.5 micron stone (shown in picture) installed in a 1/2" NPT stainless steel tee fitting. This method is difficult to implement with any consistency as the two flow rates (pure oxygen and wort) must be carefully controlled to avoid inconsistent oxygenation. We recommend instead that pure oxygen be added after the wort is in the fermenter as it is easier to control the level of dissolved oxygen.
