I recently put together an in-line Oxygen/CO2 Injection device together and thought I would share it. I’m trying to emulate how larger breweries control and simplify their processes. I gathered some tri-clamp pieces and purchased a 6” X 2 micron diffusing stone with 1 ½” tri-clamp
. I connected a female quick disconnect on a swivel to the ¼” FNPT connection on the diffusing stone. I placed it in a 1 ½” tri-clover T, put a 1 ½” sight glass and 1 ½” tri-clamp - CamLok quick connects on the In/Out.
Here is a video to show how it goes together and functions.
