A 15-year-old square o-ring has deteriorated to the point that it can't hold the seal, and propane leaks around it. I have exhausted myself searching for a suitable replacement.
The seal in question is part of the stove, not the regulator. It's on the nipple which the regulator pipe threads onto when connecting the regulator pipe to the stove.
The branding on the stove is "Coleman" and "Camp Chef," and model markings say "Mountain Series" and "Everest." It's about 15 years old and uses those 1-pound green propane bottles.
Is anyone aware of a way to get a replacement for this ring seal? I've trolled Coleman, Amazon and a bunch of different o-ring retailers and manufacturers. I'm honestly considering fabricating one if I can't find one. Without it the stove is un-useable, it just seems obscene to throw it away.
