Quoted from Homepin:
I will cutNpaste here from AA regarding my answer to this question over there about silicon:
Q: "Have you considered silicon rings instead of rubber?"
A: Yes and we have played with silicon. If you nick silicon, even the slightest of nicks, the ring will split in seconds - it isn't long enough lasting for a "manufacturer" to use I'm afraid.
For after market use - no problem because it won't reflect on the manufacturer of the machine if/when they split.
Not worth the risk for us with so many other "unknown factors" already to contend with - at this early stage we sure don't need any more than we already have believe me!!!
Totally agree on this. Silicon cleans up so well but breaks so easily!
