Some time ago, there was a discussion about Oil Cooler Adaptor Gaskets. Because a factory original part was no longer made and is not available, there have been a number of field fixes, adaptations, and repair possibilities discussed.

A question was raised about what the factory part measurements are and if they were available in any way. Doing some work on a local coach this winter I removed the Oil Cooler Adaptor Gasket to repair a leak and found what I believe must be an original gasket with an original profile. After our discussions I was quite surprised at what I found.

I've measured the old gasket and present to you what I found. The old gasket had a Tee Profile with sharp edges and no evidence of extrusion or major distortion, therefore it represents pretty accurately, the shape that was originally installed. Fluctuations in actual measurements can be expected by the stresses of installation pressures.

This posting is simply sharing what I found and adding to the knowledge base.(as I promised)

Check out the following pictures.
