Rubber grommets for tube socket holes?

[Captain chunkulus]

Anu of you guys ever used these or know where to Source the material for them? They look just like their regular grommets. However, I couldn't find these anywhere. Went to several hardware stores nobody has these.

I like the soft silicone o-rings. I use one for each mounting screw on the top-side between the tube socket and the chassis with a second o-ring between the mounting screw nut and the chassis on the underneath side.

haven't used it in your application, I get it from Napa, used as car trim, I like metal "grippy" fingers "inside the channel" of rubber

My bad, you said grommets, I showed you o-rings. McMaster has the soft silicone grommets as well.

I like the silicone because it is softer than rubber and is good up to 450 degrees Fahrenheit. Do not exceed this limit as all hell breaks loose at Fahrenheit 451.

The o-rings in the right diameter are good tube dampeners.
