Click for larger image. | When applying aerosol-foam sealants, I often need to insulate a gap that is too narrow for the plastic tube that comes with the foam.
The accompanying drawing shows how I modify the tube to get it to fit in tight places.
- Before I push the tube into the can, I heat a short section of the tube over a torch.
- I keep the tube rotating so that it doesn’t burn, and when it gets soft enough, I stretch the tube. This action narrows the tube’s diameter.
- When the plastic has cooled, I simply snip the tube to match the diameter of the bead I want to create.
