    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.

I work for a company that makes commersial aviation parts, and we use tons of O-rings and rubber gaskets. We won't stock anything without the "cure date" due to shelf life concerns. These parts typically come in sealed plastic bags for the most part and the rubber is dry, no goop of any sort on the outside.

Aviation parts are a special case. Parts whose failure can cause a crash have very special requirements. "Cure Date" is essentially the manufacturing date.That's when deterioration starts. Dry parts, stored in the dark, in the form that they'll be used, last the longest. As rubber chemists improve things, life expectancy increases.

When I was a kid, we were always warned to not roll up electrical cords, because the rubber insulation would crack and expose the conductors. That was true. Now we use plastic insulation, and I don't recall ever seeing it crack.
