Bob,  Would you mind explaining your reasoning?   Thanks.  --J.B.



Hi JB,
 
Gosh, i thought that would be obvious. 
 
First, Polyacrylate is the same material that the second generation of Chev  
pushrod tube O-rings were made of......that failed just as rapidly as the 
Buna-N  ones. Polyacrylate has a much lower temperature acceptance than Viton. So, 
since  Viton was a superior material for O-rings, it too is superior for the 
bell  housing seal. In my experience, viton wears and seals just as well as 
the  others. It just lasts longer before hardening up and failing to seal.
 
That is coupled with the problem that this seal is so difficult to replace  
when it fails. You want to use the best seal possible.
 
Then there are always the comments from Larry Claypool that the Viton  seal 
is all he ever uses......
 
Then there is my experience of having to replace many a hard-as-rocks bell  
housing seal that wouldn't seal.
 
Regards,
Bob Helt
