Don't confuse silicone grease with a sealant.  Silicone grease is a lubricant which some people use on threads, taking advantage of it's hydrophobic properties.

 

Pure silicone grease.  The stuff sold for scuba gear is good.

Hej sneeldip,

 

i went through some silicones - actually also some "fancy indian ones".

 

The best two i have used:

- TWSBI Silicone Oil (but it apparently reacts to certain liquids/inks)

- Bayer/Obermeier Korasilon (i use the medium viscous one, there are different ones, and it is by far the best one)

 

As a hint i would suggest you search at diver stores and look after "non reacting" ones.

Divers apparently use silicone extensively.

 

Best regards

Berg

There is also Liquid PTFE sealant for sealing water, compressed air, steam, oil, natural gas, etc.  Why not ink?...  However it is not reversible as silicone is, so I would be very cautious to use it.
