I've posted about this before, but unless Coleman found an everlasting rubber compound, what are you meant to do when the cap seal gets hard and needs replacing? Surely someone must sell new cap washers or do I have to make my own?
Ken has it right, Old Coleman Parts OCP, the American equivalent of the Fettlebox. Mike at OCP sponsors the Coleman Collectors Forum like Ross does this forum and CPL. You have a choice of a one piece cap, a three piece cap, 242 size cap and possibly a 427 cap. Since you didn't specify which lantern or stove you have. Early 500 stoves use the very small 242 lantern size cap. Later stoves like the 502, all (I think) suitcases use either the 3 piece or one piece depending on age. Some heat the cap with a torch and bur the old gasket out. I use a small jeweler's screwdriver with a blade the same width as the gasket as a chisel and scrape the old gasket out.
O-rings. @Colin Geer , seriously - that's all they are, and I'd like to think they aren't that difficult to get over in the UK, Brexit or otherwise. Murph
There's lots of them on ebay, for instance this: https://www.ebay.com/itm/Coleman-La...h=item1cc86c2979:g:qbAAAOSwozNcUm9Y:rk:2:pf:0 I buy from old coleman parts, never had a complaint. Tron
I'm sure O-rings work fine, but as inexpensive and easy to find as the right parts are, one might as well use the correct part. I've only NEEDED to replace a couple fuel cap gaskets out of over a dozen Coleman appliances.
O-rings will work in a pinch, but it's often hard to be sure of the material. OCP and Fettlebox do a good job of supporting the forums and I for one feel duty bound to support those businesses when I can. Add to that that both Ross and Mike give service above and beyond the call and there's really no reason not to buy the right stuff from the right folks. The flat gaskets work better in the long run IMHO and it's one less point of failure to worry about.
I was on the point of ordering a pack of ten washers from Basnett - absolutely perfect for my needs - until the shipping alone turned out to be $18! I think I'll make my own!
Most of my washers for Coleman are from Basnett. I have placed orders with them 3 times. Great washers. That said, there have been some that say the orders never get filled. If I needed them now, I would order from OCP.
Hi, I didn't know if Basnett's sells outside the US (I now know they do, if the shipping cost doesn't kill the deal), but I've used their fuel cap gaskets for several years, and they seem to hold up quite well. I'm guessing they're made of a Viton type material such as Ross uses for The Fettlebox gaskets. Even if you can't/don't buy from them, there are some helpful hints in their blog about replacing old "cooked on" gaskets. Rick C
I've made myself some Coleman single piece washers from 2.5mm Viton and they seem OK. They're a little thinner than the original but they don't fall out and keep the pressure. Next I need to buy some 3mm or 4mm Viton, but the punch set I got for Christmas does a good job.
@Colin Geer @Spiritburner Any one can get a machinist to make a die or buy a die cut set online. You just need the correct type material that is fuel resistant. Create at cottage business and make and sell then and make some money to impress your better half ( Girls come first if you expect to keep them around ) and have a wee amount of cash to support your GPA addiction. You just need to find proper material. Here a link to suitable material any thing Greater than 1 will not work for fuels. http://mykin.com/rubber-chemical-resistance-chart
