    Hi

    I’d like to know has anyone tried to use RTV
    “ gasket maker “ to make his own gasket ??

    I have a primus 8r, svea 123 and a couple of stoves thinking of trying this method without making a mess

    i looked for couple of RTVs with high temp, but really not sure if it work for fuel cap gasket

    I’m not sure what you mean by “RTV”, but if it’s silicon-based you might run into big problems with it disintegrating in contact with fuel.

    For “rubber” washers, viton is preferred as it is very stable with gasoline, kerosene and alcohol.

    Put some RTV in a jar of Coleman fuel for a few months and see what happens.

    I was given some “special” NRV pips a few moths ago. One week in Coleman fuel and it started to turn black.

    Cheers

    I wouldn't recommend it (RTV) video is just one example of what can happen.
    In your case with a RTV cap gasket, potential of the same but different.
    If you want to skip to the action, 4.30 is where things heat up.

    @KWT The stove you mention are common stoves for which parts are readily available at reasonable costs. Why spend time and money trying to reinvent, in a poor manner, a wheel that is tested and reliable? You will spend more on a tube of RTV than the cost of overhaul kits for two or three stoves. If you've just got to do it yourself, buy one of the double hole punch sets and a sheet of viton and you'll never have to buy another gasket and the ones you make will work.

    RTV gasket maker is very much soluble in gasoline. It will not work at all.

    My understanding of that use is for something that will not be taken apart without replacing the 'gasket'.
    With stove seals, they are reused every time you remove the cap.

    @Tony Press: Good advice regarding testing it in CF prior to using.

    I see that you're in the US. If you don't have enough needed parts to justify the overseas shipping cost, Coleman 1-piece fuel cap gaskets fit the fuel caps of those stoves. They're a buck each at OldColemanParts.com He'll refund some of the shipping if it's a small/light order.

    I hope not. I too laughed at that video. Perhaps because I've had my own incident with invisible alcohol flames. At least I was outdoors at the time.
