Water guages

[Martin CusdenParticipant @martincusden44107]

Does anybody have a contact for silicon tubing suitable for sealing guage glasses. It needs to be about 5mm, 6mm, and 8mm. ID

Silicon tubing

[nigel jones 5Participant @nigeljones5]

hi..they sell it by the mile on ebay. I dont like the stuff myself. I use a bit of ptfe tape and a smidge of bearing lock – guaranteed never to leak!

I bought a few sizes (EBay – medical/food supply) and cut thin o-rings. The problem is that the silicon tube wall is around 1.5mm thick and would not go into the fitting. I successfully made it work by stretching a smaller bore, but it was a fiddle. Much easier are the 1mm thick o-rings from Reeves, and they are only about 30p. I used two at each end with a touch of silicon grease. I also agree with the PTFE tape and Foliac (steam seal) solution.

I've used the thin section O rings that Reeves sell for the purpose
