seal for tree through sheet metal

[Davimont]

a good weekend to all.
I have a 18-inch tree that crosses a 2mm sheet. I have to seal this passage to avoid the passage of dust but I do not find seals (type gaucho to understand us) that can be inserted on a similar thickness.

I imagined a gasket with external groove but I don't get anything.
Do you have any advice?

It's already a good start! I did not treat these articles and therefore I did not know them.

Now I see if they can go well for my application.

thanks focus!

long ago, I had to design/design/model a structure that isolated the outside environment from the interior through lexan panels. My boss used emka profile seals.
in practice, they are "c" or "u" seals. insert the sheet thickness in the part between the two lips (in the two lips there is a steel wire that stiffens the "c"/"u").
I would opt for the seal in the second image (the only one indicated with the black arrow, to understand). the one I have indicated has the two lips and, on the side of this last, there is another layer of rubber that guarantees the seal.

whether it is a fixed pipe or a rotary shaft, the best dust seal but also for liquids, you can get it by crushing a flat circular seal, inner diameter equal to the diameter of the tube, with a metal circular ring close to the sheet with 4 screws.

on provo...v-ring?

I agree with you @ focus on the v-ring solution; it is simple and economical and it is good both that the tree is rotating and static. is the solution normally used on electric motors.

I already use that type of seals for other purposes and fit well to quite large arches, I have to insert it in a 20mm hole so too small. Thanks anyway.

good idea, I will keep it present for other applications but maintenance for this application has rejected it.

I think it's the best way.
I asked my supplier to send me a couple to do a test.


thanks to all for the advice.
