OK Jay,
Looking at the quality, complexity and cost of the other items here I have something for you to look at. A lot of people are using corny kegs and are attempting to limit oxygen uptake at all stages post fermentation. The most common way to "purge" a keg is to fill it with a StarSan solution and then push this solution through the outlet post. However, due to the physical design of the lid approximately 2 floz of air cannot be purged from inside of the pressure relief on the keg lid, as shown below. This 2 oz is WAY above the recommended O2 levels at packaging.
My thought is to drill out the cast pressure relief and replace it with a welded on 1/4" coupling. The coupling would have to be modified by, removing some of the threading, drilling the relief holes, adding a section of sheet/washer/ect to hold the spring compressed. Off some quick measurements we would be looking like something below.
Do you think this is economically feasible?
