Do I have to have one of these? I was cleaning my pin lock kegs that I bought a while ago and noticed that they don't have gas dip tubes.

No I haven't pressurized then yet. I will try when I get home and see what happens.

The keg will leak without the tube and o'ring because the tube supports the o'ring so it will seal on the sides as well as the tube itself. You need to find the tubes or have a machinist make a solid machined version of the tube.
Look closer. Pinlocks have VERY short gas tubes. I mean, like 1/4" long, just enough to hold the Oring in place. It's pretty common for the tube to stick inside the post when you remove it.

Yuppers... I wondered where half of mine were when I was breaking them down...

WHAT?!?!?!
Sure they do. The o-ring on the dip tube applies upward pressure on the poppets to keep them sealed.
They also apply downward pressure on the Oring so that it bulges outward to seal between the post and keg.

Yep, that's what the post does...
What about flowing co2 through into the keg? Isn't that something?

I just assumed there weren't dip tubes because I ran my hand over the inside of the keg where the tube should stick out and there was nothing there. If there is a dip tube there what is the best way to get it out?
