Can you I.D. this Firestone keg?

[smokinghole]

Well I'm almost certain it's type B and I need the relief valve to screw onto the keg. These kegs don't have the same lid as cornys everyone else is used to. Unless you some how have this figured out I'm open to any ideas. I'm lost at this point basically and my understand is that I will either need to adapt the threaded post on the keg or track down the what I think would be type B or something that can take it's place.

I have several kegs with the type "B" relief - It just screws together with the "Nut" on one side and the "Valve" of the other. It's just a round hole in the lid of the keg. You should be able to adapt that without any real engineering required, I would think...

Unfortunately, they don't make the "B" relief valves any more, and the usual answer to "I broke mine" is to buy a whole new lid with the Corny "Screw in ring" type relief

That damn lid is weird and I have no idea what the thumb screw with the internal piece is for.

Tightening the wingnut causes the inner part of the lid to squeeze the o-ring outward against the keg neck to make it seal. It doesn't have any self-sealing when the keg is pressurized like a common Corney does.

Just had a thought. Do you know what the threads are for the pressure relief? Conceivably we might be able to use something from an air compressor.

It's 7/16-27...not a common size. In fact, it's totally uncommon.

I got a response from Williams brewing.

Well? What did they say?

Okay I haven't quite given up. So do you think it's type B or type D for the pressure relief?

If your relief valve post has external threads, that only leaves the B valve.

Williams basically said it's old and didn't know much but I have determined that the liquid and gas posts can be purchased there. Along with the gas diptube which you know. I might order a SS version as well in order to modify.

As for the relief valve type B cannot be had and I doubt that'd actually work. I will talk to my buddy with a machine shop hookup for an adapter or something else to be done. I'm going to modify this thing to work some how. When I figure it out I'll let you know.

I'm headed to a beverage service company in the next couple days. Maybe they can shine some light but I'm not holding my breath.

I don't think any of the available stainless gas tubes are going to easy to modify. It would be easier to have your machinist hookup just duplicate the plastic one out of SS.

Well I exhausted any and all local avenues for this keg which I'm sure was going to happen. I had to try anyhow. The service guys at the beverage company said fat chance. So I'll call my buddy with the machinist hookup and grab me the posts for the keg along with a normal corny lid and pressure relief. Then I'll see if I can get him to machine an adapter to screw onto the weird threads and screw the current style pressure relief into the adapter. If I successfully get one made would you like one? Or would it depend on cost?

Don't worry about getting one for me. I can have one made for what amounts to being free. My keg only cam with the lid and liquid dip tube, so I still have to get the posts, poppets, etc before I can use it and I'm not in a hurry. If I keep finding Corney kegs set out by peoples' trash(found two more a while back; one ball and one pin), I'll be in even less of a hurry.

Maybe I'll clean up this old 10gal, sell it, and put the money toward a newer one from CHI...

I know it's been a while since this thread had some action but I have news. I just purchased another one of these with a funnel welded onto the bottom of it for use as a homemade conical. The good news it has the ball lock connection and even the pressure relief valve along with the lid Oring. So it looks like I can use this new purchase as my fermentor and the one I already have as a serving keg in the future. Will supply info and pics of the pressure relief valve for all to see once I replace the batteries in my camera.

I bought this as a replacement for the B pressure relief valve

I know it's an old thread and many of the pictures are missing. I have what appears to be described in some of these posts. There is no thumbscrew looking piece and I cannot get it to seal. I have a gasket it fits around the inside wall of the lid snugly but no seal. There are three equidistant holes on the lid's side, cleanly bored, no threads. The relief valves appears to be a D from above. The writing on the keg says this is a Firestone Challenger VI. .
