They have a fuse-like safety device screwed into the lid, and once "tripped" it has to be replaced. It's plastic and when the pressure exceeds the predetermined value, the plastic device gives way and releases the pressure. You then have to buy a new plastic screw piece and replace it.

One of these came with my kit when I got my keg from kegconnection:
It's a pretty handy little tool for pin lock people.

IMO, a common misconception. Because of turbulence, the air and injected CO2 readily mix and become homogeneous. This activity would be more accurately referred to as diluting the air with CO2. It certainly works to reduce the oxygen to acceptable levels in the keg, but there is no stratification of the air and CO2 while performing the action.

I am a big boy. What pressure do they vent at? I occasionally pressurize as high as 65PSI to burst carb.

Also my pin locks unscrew and can go over the tube or not. Easy to switch a gas in from an unused keg or switch them on the same keg.

Also, having the CO2 come in the dip tube is still just mixing, but I bet it is one hell of a lot more effective than dumping CO2 on top of the
O2.

Thanks for the replies! I probably over did it my first time.

This seems super tedious. I just rack from my fermentation vessel to my keg using longer tubing that will touch the bottom of the keg. This will minimize the amount of O2 hitting my beer to avoid oxidation. This being the case only the head space needs to be purged to remove any excess O2. Displacing the O2 is very easy if you use one of the tools aspiffymofo posted. They are cheap alone and come free when you by from kegconnection.

Removing the liquid out line to put a gas in seems unnecessary or getting a dedicated liquid post only for gas purges doesn't sound quite right. I don't mean to come off as insulting, just seems like more work than needed.

The pinlock connects screw off pretty easily from the hoses for that matter.

I syphon with a hose at the bottom too, I think everyone does. Purging is a step further.

Yeah I hear ya! Just trying to avoid more work lol. Once again I will state I'm not trying to sound pompous or anything.
