    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Carbs & O-rings

The equipment that I make my living repairing and rebuilding (air path and
vacuum path spectrometers) use quite a few o-rings. These machines need to be air tight to operate properly. I also repair carbon/sulfur and
nitrogen/oxygen analyzers. These machines are a small induction furnace
that use nitrogen, helium and argon as carrier gasses. These also need to
be air tight to operate properly.

Being that these GS's need to be sealed air tight, I think the GS would
be a good use for this product. The intake o-rings and the inside of the
intake boots would come to mind. I sure someone can think of more uses
for it also.

Dow Corning High Vacuum Grease is a stiff, nonmelting silicone lubricating material and has much higher stability at the higher end of the temperature range(-40? C to 200? C), than hydrocarbon greases such as Apiezon? M, However, its initial room temperature pumpdown characteristics are not as quite as good taking noticeably longer to out-gas. This grease is very popular as a general laboratory lubricant, in large part to its low costhttp://www.2spi.com/catalog/vac/vacumain2.html. The product is very popular as a stop cock grease as well as for use as an anti-seize grease in ground glass joints. It is the recommended replacement for Dow Corning Stop Cock Grease. Dow Corning High Vacuum Grease is also used to lubricate synthetic and silicone rubber gaskets being used in high temperature applications.

dow corning makes another great lube that i use for o-rings, its 111 in a green tube. I believe it's for valves but it is tacky to hold the o-rings in place.

There's probably enough in this tube to last the rest of your life. Considering how
far a tube if this will go, $25.00s is really a good bargain. Heck you can go halves
and split the tube with a friend.

I usually have so much stuff with me on a service call, I squeeze some into a
little round tin instead of taking the whole tube. Lightens my load.
