The Seal & O-ring dimension for cylinders are listed below, while "Diagram #" please refer to Lynns' post.

These dimensions are my measurment from the same seals&orings that I had used to repair my cylinders, and they have work fine for more than 1 month. Probably there is minor difference from the orginal MB parts, but they did work very well. If any friend knows the difference from MB's, please post to advise.

Also If any member is successful of obtaining the maker source, please kindly let us know.

I have to say, it is very easy to ask my friend to sell them to anyone who likes DIY, but I still think the "customer made" seals are not cheap and not recommended. (because of sharing the die cost)
