My trick with the plywood stretcher worked great after only two days.
That TES water O-ring lies in the slot no problem. Here is a picture.

Neat idea, Paul

    Now how much do you charge for this service {:>)?

I mentioned this trick to Jeff Chrysler at Creavey when I ordered some smaller
section oil control O-rings and he said warm them up to 200 degrees F and they
will take a set sooner.

Hi Gang;
      Having a tremendous amount of design/manufacturing
experience with Pharmaceutical production equipment (A
big user of TFE seals), I agree with Mr. Chrysler 100%.

Teflon seals should not be installed or STRETCHED at
AMBIENT TEMPERATURES even if you live in the dessert,
this will definitely cause "necking  down of areas" and
deep "creases" (indentations), which are IMPOSSIBLE to
repair. It also "stress reliefs" them.

A while back, I designed a "Hot Box" which slowly
brought the seal to a target of 190-210 degF. Saved(s) a
ton of $ and labor in the mfg assy line and field
maintenance. (I know, my fee was a very handsome % of
what I saved them in royalties for 10 yrs.) :-)

I believe I had posted the pre-heating issue about a
year ago here, I guess it was missed.

I probably forgot you posted something on this Butch. Thanks again.

I am only stretching them a little bit :-) Probably less than 
10%. No necking down so far or other adverse effects.
