Kelly/George,
I understand your frustration. I
went through a similar exercise when ordering o-rings for my 3-rotor. The
guy at Creavy (Jerry Chrysler I think was his name) was great to work
with. He’s a rotor-head from what I hear. What I finally did
to verify the correct length was to take a piece of 12 ga. romex and strip the
insulation off the wire. Lay the bare wire in the groove and shape it so
it stays in the groove all the way around to where it makes a complete circle. Then
cut it, recheck it, remove it, straighten and measure the length. It came
out within about .020 from what the calculations indicated. Also, be careful
that you’re speaking the same language as the Creavy guys. In other
words, be sure that you’re giving the diameter measured from the CL of
the o-ring and not the outside or inside. Everyone needs to be on the
same sheet here to get it right.
I’ll dig through my receipts tonight
and see if I can find my Creavy receipt. It has the final correct
measurements on it.

OK! I just got my TES "O" rings - they look
beautiful, but don't fit - bugger!!
So the sizes provided by everyone are incorrect.
Creavey Seal Coy. is in Olyphant PA
is anyone near there that can drop them an old damaged
housing, so they can trial fit the correct size "O' rings.
