Glass to metal seal
I hope my question is within the topic of this group.
Could anyone tell me if glass tubing can be fused to stainless steel tubing with a hermetic seal? If so, are there special techniques/methods that need to be followed? Would a scientific glass blower be able to do this. Any advise appreciated. Steven |

Steven You might want to enquire with http://www.indium.com/ . Indium is used in solders which can be used to solder glass and to form glass to metal seals. It's not cheap though at least in small quantities last time I asked. |

You might inquire with Randy Hansen in San Diego, he used to hang out here quite a while ago, haven't seen him in about a year, he runs his own Scientific Glass Lab and makes some really interesting pieces for working laboratories. |

Glass to metal seal
If your application were very low pressure, and the I.D. of the ss tube
allowed the glass tube to fit inside, a good grade (Dow Corning 712?) of silicon would seal it. There are also some mechanical setups that use a rubber gasket with lock nut. The nut squeezes the gasket around the glass tube, like the sight glass tubes they use to check the water levels in boilers. wrote in message ... I hope my question is within the topic of this group.
