Nova O-ring help

Drewed · 03-27-2008, 04:54 PM

I found the o-ring size chart, but have some questions on it.
Ex:
208 buna 70.

I know that buna is the type of material its made of, and 70 is the "hardness", but what size is 208? All I've been able to find on line is "english/metric measurements." I.E. 1 1/2" od x 1/8" thickness.

Am I looking at the wrong sites? Can somebody please help? At least a web site where I could order?

Thanks much!

Ok, found what I needed.

New question:

Any body know if I can replace a poly o-ring with a Teflon one?
