Viton O-Ring 19X4
To all the technical dudes out there like Beach and jzeller and anyone else who has gone and boughgt Viton replacements.
I have been looking around for the infamous O-ring and have come across several sources so getting it is not my question. I have noticed that there are several different specs for this size Viton O-ring anywhere from a 70A, 75A to a 90A on the durometer.
For those that have not heard this term before, it is a scale of durability of the O-ring to withstand a depression or deformation due to pressure on its surface and return to the original shape without leaving a dent. The higher the number, the less likely it will maintain any deformation from pressure.
I have not seen anyone mention any durometer spec for this part so I am asking, what are you using or does it even matter in this application seeing the original just doesn't hold up and any of them would be better than the original BMW part.
I just bought a bag of 10 with a durometer rating of 75A and am hoping this will be adequate as a replacement. I can hand them out locally if needed as long as they will do the job.
I am interested in what others have used in their repairs.
