Ah, I'll have to get some (and hope that it's available in small
quantities) unless there's an acceptable alternative which I already
have.

How about Vaseline? I know it degrades rubber, but modern O-rings are
neoprene or similar, aren't they?


Even if they are, I certainly wouldn't want any possibility of vaseline
in my tea...

(I realise that it shouldn't get in there, but we all know how things
don't always work out as planned.)

For the cost of a small pot of silicone grease, I would not risk it.
