Default Kegging-3/16" liquid line on 1/4" shanks/tails?

Been mowing through kegging forums and the search engine and couldn't seem to find this answer.

How concerned should I be with 3/16" line on 1/4" inch shanks/tailpieces? It seems like most vendors only carry the 1/4" shanks. Should I look around more for 3/16" shanks or is this a non-issue?

Thanks for any input here.

The line stretches over no problem. A short dip in boiling water makes it much easier.

Yep.....a dip in a coffee cup of hot water and it'll slip right on.

Don't forget hose clamps -- it might look like it's tight .... but it's a lie

My question was more one of fluid dynamics and potential for foaming than anything else. Yanno, a 3/16" tubing run hitting a 1/4" shank that's also probably room temp...

Of course I can get a 3/16 onto a 1/4....using brute force all things are possible. ;-)


bolts, saw that one today while link searching!!!!! Yeeeouch! Yep, just ordered a nice pack of small SS worm clamps from mcmaster. I am going to go threaded fittings all the way, but will definately be clamping off any barbs.

I've never had an issue with foaming that I couldn't trace to line length or pressure or temperature...

Oetiker clamps FTW!

There's a reason every beverage company on the planet uses these - They are great!
And all you need to crimp or remove one is a diagonal cutter - You really don't need the special crimper.

Bonus - They are cheaper than worm clamps, they are smaller than worm clamps, and they don't have that annoying little tail to cut you open like worm clamps!

I use them on every connection I make:

Put some duct tape over the gauge - Or better yet - Replace the high pressure gauge with a plug - High pressure gauges are useless!

+1 for no problems with foaming. You'll be fine.

Ok, that's it...I'm sold. I never used these before and thought you needed the special tool. Any special technique to this?

That is GREAT advice, thanks for posting that!

Not really.
I just crimp it with a side cutter. I crimp from one side, then flip and crimp from the other, just to get it even. YMMV. As long as your crimp pulled the 2 sides together - Regardless of what it looks like - It's tight.

To remove, simply use your side cutters between the "tail" and the "Ring. It's hard to explain, but they come right off - Essentially you have to use your cutters to peel the tail off the ring, and the punch marks that hold it down.
