I just bought 2 2g kegs.
What kind of threads are the usual pepsi (ball) air in parts designed for? I am having a heck of time trying to find something to go from machine threads to whatever Cournelious kegs use for those in/outs. Right now they have some weird kinds of pressure stuff on them, but I want to convert to standard ball in, no quick disconnects. I got one of those pellet gun things to use for mobile partying and want to use it with the minis as well. |

Corny keg threads are a riot to figure out. Good luck!

I have a host of kegs in more sizes than people even know exist. If you post a picture I might be able to walk you through what you need to convert it. |

I don't understand what the real issue is, other than you need to know thread sizes so you can do some kind of conversion of your kegs.
The threads on the ends of disconnects are 1/4" flare. The threads on the body of the corney kegs are sized as follows:
--------
Firestone V Challenger, Firestone VI Challenger, Firestone Super
Challenger
Gas 9/16"-18
Liquid 5/8" -18
Cornelius Spartan & Super Champion
Gas 19/32" - 18
Liquid 19/32" - 18
Cornelius R (pin lock)
Gas 19/32" - 18 (2-pin)
Liquid 19/32" - 18 (3-pin)
John Wood 85, Firestone Challenger
Gas 11/16" - 18
Liquid 3/4" - 18
Firestone A, Firestone R, John Wood RA, John Wood RC (pin lock)
Gas 9/16" - 18 (2-pin)
Liquid 9/16" - 18 (3-pin) |

Not always. There's a bunch of weird sized stuff out there. |

Most all the non-barbed ball lock QD's have 1/4 inch MFL fittings, but I've seen pin-lock QD's in at least two different sizes, some are 1/2 -16 flare. |

Its not the corny keg threads (not normal ones) that are bugging me. It is the tops (air in) of these non-normal kegs.
Well I tried to post some images, but they failed to load becuase they were too big. Don't feel like screwing with them.
What I need to know is - what exactly is the threads on a corny keg so I can find and buy something EXACTLY like them. They are not compression. They are not pipe thread. What are they!?! I don't think they are 1/4" flare becuase the 1/4" flare compression are too finely threaded, and the pipe 1/4" flare are too coursely thread. The thread count is somewhere in between.
I suspect I need to go some experts at a plumbing or machine place. Once I know the part that can thread into the ball gas in, I can figure out something to connect it to these kegs. |

Find a Swagelok dealer in your area and then carry your keg with you when you go there. They will be able to match the fitting type and design so that you can convert to the typical ball lock connector as a final result.
It is my guess that your keg has some very specialized fittings on it. They WILL be Swagelok fittings - IMHO ......... |

still cant read into your words wether it is a "ball gas in" as you said, which I take to mean ball lock, or is it simply an odd notcompression,notflare,notNPT threaded post welded on the top of the keg?
maybe hold up a tape and try to count the threads per inch (or per 1/4 inch and multiply by 4). Then try to guesstimate diameter.
swagelok looks no different than flared to me.
see if one of these looks like it:

as Dan said, good luck! without a better description a picture or something to go I'm stumped. |

Well....
Whoever voted the 1 star... Thank You SO MUCH..
Just so anyone that MIGHT be interested ---
Here is a 1 gallon corny 'type' keg that is an aboration.
Here it is again with Swagelok fittings applied.
I've not brought it to the point of being able to use it as a typical 'corny' keg as the fittings to bring it there seem to be rather pricy and beyond what I can afford.... My pension and Social Security does not give me much lattitude.
So - each to their own.
OK - You one star Voter... Reveal your self and tell ALL of us what the •••• you know about this subject....!!!!
(Just in case anyone wants to know - I'm really pissed over the voting system on this forum AND the blatent dis'ing of its members....!!!)
I'm done.. |

Hey, I'm with you. Why do we still have the voting system? It serves no purpose other than taking cheap and anonymous shots at people you personally dislike.
For to accuse requires less eloquence, such is man's nature, than to
excuse; and condemnation, than absolution, more resembles justice.

Paul,
I'd stay the single-star icehole knew just what kind of reaction he'd get out of you. There's no way anyone on this board has anything against you. It's just juvenile hijinks. Don't feed the animals. |

Hey Paul,
That's the cannister that I sold you, I figured it would be a pain to find all the fittings. Looks like you are almost there, just need a VCR to NPT conversion.....
Good Luck! |

I've heard that the threads on the fittings welded to the top of most corny-type kegs are NPS - National Pipe STRAIGHT (rather than NPT - Tapered). I can't confirm or deny this.
Paul, remember that you don't have to be registered/logged in to be able to rate a post.
Anyone in the world who stumbles by this site could give you 1 star so they can get their rocks off. I think someone is intentionally doing it to evoke such reactions. I also think they're probably typing with one hand because their other one is busy.
I think everyone should ignore the stars - if no one ever makes any comments about them whoever is doing it will probably lose interest. |

Myself, I'd be very leery of non traditional corney kegs. Sometimes they have been used with some very scary chemicals. Unless you know whats been stored in them, be careful. |

Is the swagelock stem welded directly to the keg? I have a bunch of those type of kegs and your center two ports seems different than anything I've seen. Most of these kegs have NPT ports or tri-clover ports. |

This Keg was originally used to hold IPA (isopropyl alchohol) for a Semiconductor wafer dryer module for the company I used to work for. So the VCR fittings were welded to this, and the inside is completely electropolished. To assure cleanliness. I have 1 other like it that is a 5 gallon version that I use as a fermenter for my lagers (it fits in my lager fridge). |

Great Jeff, thanks for making this easier on me! Just kidding.
My tops do have straight machine threads on them. And after reviewing Tom's numbers, I suspect I Have a 'ball in' that is 9/16s or something weird enough that ACE hardware did not stock the parts (forget homedepot or loes). Of course that and the 18 threads per inch was probably enough to make sure I can't find anything in the store that will connect to the "ball in" pepsi connector. However, I suspect I can take a large selection of ball ins to ACE and find something that will connect to one of them - I have most pepsi styles right now. Then buy that connection and two ball ins and find something that goes to machine threads on the lids.
Hey Paul - just gave you a 5. Anyone willing to spend time on the pics as I wans't gets a 5 in my book. |

Sorry,Andrew. But I came across some freebie kegs a few years ago that had held some carpet cleaning chemicals at one time. There was no way of removing the odor in them. They even had some strange color inside. Both of them went to the scrap yard. I did manage to trade them for a sanke keg though. |

Corny kegs are often the vessels of choice for meth labs. |
