    Hi ya'll

    The other day Brerarnold was asking about Coleman filler cap gaskets with respect to his 426B. Link

    I needed to change one out anyway, so I took some pics of my procedure. Once again, sorry if they aren't all quite in focus. My good camera died and I'm using this backup until I can get a new good one.

    The three parts of an old Coleman filler cap. There is a gasket in place on the brass insert though it is hard to tell.

    1244830454-PICT3709.jpg 1244830462-PICT3711.jpg

    Once heated nice and toasty with a propane torch the gasket in the insert poofs up and out of the groove in the insert.

    Gasket scraped out with a dental tool.
    There it is! See it now?

    1244830473-PICT3714.jpg

    Gasket completely out. Then, I remove any residue with 0000 steel wool as the one I've already done on the right.

    I fit o-rings to my Coleman caps. They cost me 5 cents each at the local hydraulic equipment repair/supplier. They work great.

    Cap all reassembled and ready to go. Once installed on the lantern/stove, I tighten the center screw nicely.

    Hope this helps those of you who are needing to do this replacement.

    Cheers,
    Gary

    Hi Gary, Thanks for the great post with pics! I didnt have any type of torch, so I just held on to the cap with a pair of pliers and melted it over the stove :shock: with the overhead fan on. :oops: (dont thel the missus). Then used a similar tool to scrape away the rest of the oring.

    Thanks guys! :)

    I need to say that it's not my idea. I learned about it here:-

    (dead link to old town yucca site removed by Mod...)

    (OK. I guess the o-ring was my idea.) :oops:

    There (edit - was) lot of good technical repair info for Colemans at that site.

    Cheers,
    Gary

    Hi all: Gary; great minds think alike. I have been using o-rings also from a hydraulic parts supplier for about 30+ YRS. they are the ticket. They are pressure and chemical resistant where as auto parts and hardware o-rings just don't hold up. Most pre WW11 Coleman's use lead rings that never go bad unless mistreated. Mike...

    That's a great description and great photos, Gary!

    I took the loafer's way out and replaced the entire cap. :whistle:

    Be careful that the o-ring is not too fat. Even if it is the right diameter, if its too fat the tank may not adequately vent as you loosen the cap. If this happens you will know when the cap is expelled and you are holding a cyclone of gas vapor in your hand.

    Some o-rings may "settle down" once clamped in place for a period of time.

    Got an assorted package of (vitron??) injector seals at the auto store that had a few that worked OK.

    I just did this on the old cap for my 502, worked great!
    With the right size O-ring, the sod slipped right into the rolled edge where the fibre gasket came out,and all was well with the world! :clap:

    When I get in to work at Ace hardware, I'll write the size down and post it for all here!

    Here's the dimensions of the O-ring I'm using here:

    11/16" x 1/2" X 3/32"

    Our ACE part (SKU) number here is 4072427

    Here is a picture of the 'fiber-like' material I found in my filler cap. Water test resulted in leaking, so I am going to get an o-ring for it. It doesn't look burnt, and the stove looks barely used. Anyone else seen this kind of material in a Coleman stove?

    snwcmpr, if there is a Harbor Freight store near you, they carry a 250 piece assortment of nitrile O-rings for about $6. Yes, made in China but they work just fine.

    As for that gasket from Coleman, I believe they area blend of asbestos, spotted owl feathers and humpback whale blubber.

    I got an o-ring from NAPA yesterday. $0.59
    Will burn it then brew coffee in the vintage Cory Vacuum pot today.

    Why not just use high temperature gasket maker silicone for gasket/o-ring replacement ???

    Another good source for high quality cap gaskets is Fred Kuntz. I think they are around 25 cents each and he has many different sizes.

    yep, i learned the same technique of burning out the old gaskets from a youtube video.
    Cigar Mike burns out gaskets the same way.
    the O-ring is new to me but i will give it a go the next time i replace a cap gasket. thanks for the info Gary.

    i found something like hemp twine in a cap once. i was out of gaskets at the time and never thought about using O-rings.
