Quick-disconnect airlock for corny keg? (is there a better way?)

[Trauts]

Is there a better way to hook up an airlock to the gas post on my cornelius keg? This seems... overcomplicated. I know there are drilled lids... that's not what I want.

Mock up of what I've come up with so far:

Barbed fitting to blow-off tube is what I would do.

yup. Remove poppet from gas-in post. Re-install post. Use 3" of 3/8" silicone hose and apply over top of gas in post. Insert air lock into hose

When done, remove airlock hose and post, and insert poppet. Re-install post. Purge with CO2. Very little should be needed......

I used to use a short piece of vinyl tubing over the 1/4" threads of the QD connector, going to a portion of racking cane from the bent part, and then another short piece of vinyl tubing to connect up to a bubbler.

Your better off just building a spunding valve

Slightly off-topic, but might be a solution for your problem.
This question got me wondering if there is a reason we don't use backflow check valves for airlocks.

The simplest thing in the world is to just use a gas QD with a barb fitting, and place a tube over that running to a jar of sanitizer. This makes a simple, cheap airlock.

A multi-piece plastic airlock is not practical, as illustrated by the Rube Goldberg collection of parts needed to attach it. But more importantly, it's not necessary either.

As long as you're careful to disconnect before cold crashing, to avoid suckback. It's kinda easier to forget that kind of thing when fermenting in kegs.

Is it just a one way valve? The problem there would be getting a vacuum in a corny if you seal it up before it completely cools and starts producing CO2. I don't think corny's are able to handle vacuums well.
