The one’s from Elring fall in between those that were in and the green one.

Measurements are the same between 2 set of Green and 4 set of Red/Brown.

The large Red/Brown got almost a glossy finish when compare to the small one.

The Elring ones fall in between the Red and Green.

The green ones are always Taller, smallest O/D, biggest I/D and the thinnest one.

So I put the Elring one in, torque to 25mm and its not leaking in a static condition like the green one was.
