Hi Mark,

It is best if you send the o-rings back to be reworked. Silicone
glue is not
very strong without the support of a Teflon jacket to hold it
together.


The rings will be cut down and made to an 11.155" ID so that the
ring OD
will be close to or snug with the outside groove diameter of
11.340.

If you wish the rings to be snug to the groove ID they can be cut
down to
11.110" ID but this probably is not as ideal due to pressure
traveling
outward.

Awaiting your answer.

Best regards,

Jeff Chrysler

       Mark,

        What final dimension have you and Jeff Chrysler come up with
for the
    outer coolent TES O-ring?

Kelly,
I verified the circumference of 11.340 CL by using a 3.32" aluminum welding
rod laid into the outer groove, bringing it around until the ends touched, cut
at that point, then straighten it out and measured it.  Creavey apparently
prefers to work with ID, so they subtracted .100" from my measurement to come
up with 11.240 ID.  I have not received the reworked O-rings, so I would
recommend you wait until I can verify that these actually fit as intended.
They were shipped UPS ground on 5/14, so I should have them in hand by mid-
week.  I'll send an update once I have checked them.

P.S.  Jeff Gillette has been great to work with and I highly recommend Creavey
Seal.  However, that may change if we keep sending our o-rings back for re-
work.  ;-)  I'll post the results next week.
