Newbie here. I have a 4 button air button control panel. It says "Hercules". I need to replace the air button bellows. They are about 1 inch in diameter. They look just like HGA air bellows part number 6444-04 (which I ordered). However the ones I ordered are more like 1.25 inches in diameter. Anyone know where I can find ones similar to the 6444-04 but only 1 inch in diameter?

I did a pretty exhaustive web search but no cigar.

Bump. Here is a photo of the too large diameter bellows (1.25"). I'm looking for the same style but 1" diameter.
Thanks

Bump. The air button on the left is the one I need. The one on the right is the HGA model number that is too large. Anybody?
