Oil filter O-ring size

[myturbo]

Does anyone know the o-ring size for the smaller o-ring used with the oil filter for the 996 TT? I have an oil filter from my C2, but it only has the larger o-ring included.  Porsche does not offer the smaller o-ring by itself.  It only comes with the filter purchase.

The part number is sold separately and retails for about $6.  http://www.sunsetporscheparts.com/oe-porsche/99970746540

Good grief guys, $6 for a 10 mm o-ring  :huh:

 

Anything special about it? I've reused them in the past, contemplated just using a plain nitrile ring, is it viton or some other exotic?
