Question on burner gaskets

[Painter590]

I've been working on the camel back and have a question about my propane burner. It is in three pieces and I'm curious if it needs any type of gasket in between the pieces.

126 people looked at my question. Not one person can tell me what kind of gasket material I need to use.

cannot tell if it NEEDS a gasket from the picture, but if you are going to use a gasket (because the faces don't seal)

I would use compressed asbestos.

but since that is difficult to find (except in my basement next to the lead paint), you can find something here

the area doesn't get all that hot, but you do need something that will seal and stay sealed.

the graphite stuff is very durable...a bit difficult to work with but properly done will outlive all of us.

Bill thank you kindly.

I have not built one, but I agree that a gasket would be a good idea, just in case. You really do want the gas escaping only at the desired locations.

I know the gas pressures are very low, and it simply cannot build up very much pressure, since the outlet holes are close by anyway.

It may also help you to separate the pieces later, if they tended to rust together.

It could be that the lack of response is due to the fact that many haven't seen a burner that looks anything like what you describe. That vast majority of propane burners seen are individual burners on a manifold or slotted pipe burners. I wasn't quite sure what I was looking at when I first saw the post. Having said that, everything should be sealed accept where the gas exits.

I would ditto the need for a gasket.
on large boilers we see a lot of fiberglass type material held in place with waterglass and then assembled. many wood stove places carry the flat gasket material and waterglass.

[Bill Shields]

I would not recommend use fiberglass in this application.

Making it totally air-tight is not easy. it can leak...and a leak in this area can be a problem.

you want something SOLID

another thought...use soft copper sheet..

Here is a photo of the burner assemble together.

Here is a photo of where I want the flames.

I believe Mr Gasket still makes automotive exhaust manifold gasket material available in sheets. Any type of sheet material with "vitamin A" substitute should be ample.
