Done with MFLs for my corny connectors

[HutBrew]

Just had my 10# tank bleed out for the second time, due to a bad connection between the gas MFL and the nut&barb.

I’m sticking to barb connects exclusively.
Anyone else experience similar frustrations?

I have. But I still stubbornly like the MFLs anyway. Now I remember to check them occasionally and tighten whenever I put a keg in the kegerator.

Thanks for the input Yooper! I know they must work, but are not entirely fool proof... I hate admitting user error, but that’s gotta be it.

No, it happens. It's just that convenience of being able to swap out the connections outweighs the problems I've had.

Just to add, always use one of them little conical flare nylon washers if it's a metal to metal contact. Most of my quick disconnects have a plastic nib end that acts as the washer to metal swivel nuts, but some early ones I had did not and I *HAD* to use the little nylon washers to keep them from leaking.

[Edit: Like these]

I skipped barbs and went with EVA Barrier + duotight-MFL adapters off my MFL regulator.

I was concerned about the robustness of the plastic, but so far almost 12 months in, she's been holding. Still the same original fill on the 10lb tank I started with.

The tank rarely moves, and I'm using duotight "tee" connectors in place of a manifold to feed 4 kegs. Perhaps I've been lucky, but so far so good.

this. I have a 6 tap kegerator and I think 14 kegs now with a little more than half being pin-lock.
but with MFL's i can easily use either.
I do have a wrench and I do make sure they are snug every time i move them.
I have had more tanks drain from bad o-rings on post than loose MFP's.

Here's where being obsessive is a win
I have 26 gas QDs and 8 liquid QDs in fixed service between three fridges and a keezer, and literally have never had an issue with an MFL QD with its swivel/barb while in actual service. But, every one of those connectors was dunk tested under pressure, and any problems were resolved there and then (and there were problems - missing flare washer, cracked washer, forgot-to-tighten swivel nut, etc).

Since that point I've switched everything to PTC connectors and I don't think I have a single swivel nut in my entire cold side - and I still don't have any leaks, but then again, when I converted I dunk tested (or at least seriously sprayed down with bubble soap ) every one of those connections...

Cheers!

Thanks for all the input folks! Looking back I must have forgotten to tighten the swivel nut properly, and this is how the leak likely occurred.
I’ll probably stick with all barbs for now, but I appreciate all the feedback!

From an engineering perspective, the more potential leak points, the more opportunity for leaks. Adding more glands and packings than necessary comes at a price.
