Anyone know where I can find a source for weld in bungs for a Degas bottle coolant cap like this?
This is a link to a Canton tank that has the bung I'm looking for but I don't see the bung for sale separately in their catalog and haven't had luck finding one through Google

If you are looking for the weld in bung for the factory cap you will have to make it or call canton and see if they will sell you one before it gets welded into a tank..

Meziere makes bunch of different caps. Their website sucks. But here is the first one I found.

If you search weld in bungs and fittings on Summit Racing, you get a pretty good list of their caps if you search under their brand name first.

I am specifically looking for a bung for a coolant bottle factory Degas style cap as shown in that pic. I've gone through the listings at Atech and even emailed my rep to see if they've got a listing for it. I am so surprised that these aren't all over the market since they've been using these caps for over a decade now.
I may have to call Canton directly to see if they would sell me a couple..... or get my CAD guy to draw one up and I can start selling them!! :idea:

I remember these at Speedway but found it on Jegs.

not sure what the thread pitch you need if you are looking to use the stock cap.

Just what I could use as well but I can't weld aluminum. Damn.

I've bought these threaded and O ringed caps and bungs for oil fill caps in valve covers. They're not hard to find.
Like many things it's mostly in the way you "search" for things.... I find I have to search and then refine my search as I see the way things are worded etc.
Can't get the link to post correctly -- so maybe copy and paste it instead of just clicking on it. Should take you to a page with all kinds of weld in bungs with screw
in caps

Yes, the regular bungs with O-ring caps are easy to find in a million different sizes... I'm specifically trying to find one that will allow me to use a factory style degas cap for a coolant degas bottle I'm building. Vince posted up one that might be a winner but I haven't had time to go back and measure it yet... I figured just like a standard coolant neck there would be listings that specifically mentioned it by name.
That is a great link for an excellent selection of weld in bungs though Greg!

let me know if you need anything done. I am starting to get a lot of requests to make custom aluminum tanks.

Thanks, Vince. I'll keep that in mind. That link Greg posted has some steel bungs, too.

I finally got around to measuring a factory coolant bottle with that fitting... its a 2" diameter with a 10 pitch outside thread. Im going to go back through Gregs link but I don't think I've seen anything fitting that. I should search on a diesel forum since they seem to like their billet degas tanks... but most of them I've seen have switched over to a standard rad cap.
I just called Moroso because they had a Mustang coolant tank with the bung. They sold me 2 for $10 each. I'll have them in a couple days.

Sean, I'm curious now.
Are you replicating an existing tank? How did you math your way into sizing the tank? I have to admit, this seems like a better way of doing things and solves a couple of other issues as well. I also like that the cap is a 21 lb.
I tried to see inside the tank on the new mustang but I can't determine what is in there but would love to see what you have planned. Thinking about buying the moroso tank just to see.

Found some interesting info in this article regarding tank sizing.
https://www.cumminspower.com/www/literature/applicationmanuals/t-030_p93-115.pdf
We all know coolant expands when it warms up but an actual number wasn't readily available....at least to me. It seems that 6-7% of system volume is generally accepted as volume required for expansion. That is for an overflow tank or a degas tank.
A degas tank should have a volume of 17% of the total system. 6% for the above mentioned expansion and 11% for coolant. They call it draw down capacity on page 95.
So lets assume 4 gallons of coolant in the system, not counting the tank. 17% of that is 2.7 qts, I like round numbers so 3 qts it is. 3 qts is approximately 175 cubic inches and that would be the proper size for a degas bottle/surge tank.
Right?.....
