Beer Brewing - Pin Lock (Coca Cola) to 1/2 " Water Adapter

I created this adapter to clean my pressure relief valve and it's tubing after some beer got into it. With this adapter you can easily connect the relief valve to e.g. a water hose.
You will need 2x M4*10 screws for the pins- grub screws look best - and the usual Cornelius Keg O-Rings.
