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.

 

Mark S.

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.
