I have a newly acquired used Coleman 424 Dual Burner Dual Fuel Camp Stove. I am able to pressurize the tank; however, I have a fuel drip after about 20 pumps coming from the brass nut which goes over the shutoff valve. The leak is not from the stem but coming through the threads of the brass nut. When I removed the brass nut it appeared to have had a rubber seal that had hardened over time. I do not want to buy an entire generator as that would put me at the cost of a new stove. Can I buy the brass nut or does anyone have any idea what kind of packing this will require? I am hesitant about over tightening the nut and possibly creating a dangerous situation. Trying to get ready for winter power outages. Thank you for the help.
Had you already tried tightening that nut just a tad? Usually, that will fix a small leak (until next time).
I don't have a 424 taken apart in front of me but I think that the seal should be graphite packing. But, then again, the later models did get cheaply made and rubber o-rings were being used as seals rather than graphite, which, IMHO, is a better material than a rubber o-ring, even if its viton. You can get graphite packing material at your local hardware store. sam
I have tightened the nut further than I feel comfortable doing because of the quantity of fuel leaking out. I called Coleman and they only sell the entire generator for the stove at about $45.00. I believe with safety concerns and the fact that the packing material (which I also believe to be graphite) is difficult to remove and obtain that I will return the used unit and purchase a new one. I have read too many posts regarding this issue in various forums and prefer not to cook over a Coleman bonfire! I greatly regret ever giving away my old two burner when I left for college 20 years ago but if wishes were horses than beggars would ride (as my Mom would always remind me). Thank you for all of the help.
My mom used "if wishes were horses, beggars would ride" all the time, along with many other maxims. Her mainstay, which became mine, was this one: "Laugh and the world laughs with you, cry and you cry alone".
Let me encourage you to give a try to the repair. You have nothing to lose at this point, the packing material is available and cheap https://classiccampstoves.com/threads/15-off-graphite-foil-ccs-15th-birthday.30713/ , and it is easy to do (even the first time!) Afterwards you will have a safe, reliable stove. Good luck.
I have a new packing nut assembly for a 425 I believe they are the same as a 424 if you would like I will let you have it for postage
Maybe a little off-topic, but my 424 leaked also, and i used some teflon 0.1 tape wrap around the fuel cock. The Roll-up, glogging was enough to seal everything.
