Different sized plastic dip tubes?

I got an incredible deal on a bunch of kegs from a guy last summer at $20 a piece (he even threw in one for free because the relief valve wasn't working). I just got ready to use three of them for the first time, and they all have plastic gas dip tubes that need to be replaced. Problem is, they're two different sizes.

The dip tubes for two of them are this style and have an OD of .25", so I'm assuming these would work: http://www.williamsbrewing.com/TAPERED-PLASTIC-GAS-DIP-TUBE-P2570.aspx




Here's the real problem. This one has a slightly smaller diameter. About 1/32 of an inch smaller. It doesn't sound like much, but I can't get the .25" tubes into it.





Does anyone sell smaller dip tubes, or am I going to be stuck having to drill this one to make it bigger?

 

Why do they need to replaced? If they aren't touch beer just clean and put back in. Are they cracked or something?

 

I had a similar issue, bought a Challenger IV keg that came with a warped plastic dip tube, and the normal metal dip tube that you use would not work, as they only went about a half inch in.

So I had to decide between drilling the opening or cutting the metal dip tube to about a third of an inch. After doing some research it seemed much easier to simply cut the metal dip tube down to size. Quick, easy, and it has worked great for me.

Because they leak CO2. I'm not just wanting to replace them for fun.

 

Halfway down on the right are the nylon pieces that you did not mention, but will probably need to be replaced as well, and on page 2 you will find the plastic dip tubes.

Thanks, I actually had no idea what those were and thought it was weird that there weren't any o-rings on them. Could be possible that those are the culprit and not the dip tube itself.

 

Probably the plastic insert leaking. On those I don't even think you need to install the dip tube, but if you do I would opt to replace them with stainless and just drill out the holes.
