I have had the same good luck. Did you ever try to use a lube on one side to make a removable gasket? Bruce<br><br><div class="gmail_quote">On Mon, Sep 5, 2011 at 7:56 AM, Brian D Paasch <span dir="ltr"><<a href="mailto:brian@indianarenewables.com">brian@indianarenewables.com</a>></span> wrote:<br>

We used Quad rings in milled (trepanned) recesses, with vacuum greases applied. These seals were resealable many dozens of times. I don’t know about temperature ranges available for them. In our case, we used them on the exterior joints of the vessels where the temps seldom exceeded the boiling point of water. But that was in the 1960’s, so I wouldn’t be surprised if materials have improved a lot since then. <u></u><u></u></span></b></p>
