Includes the bottom gasket against the engine case and the copper crush gasket between the top and sleeve of the adapter. I always buy two sets because the adapter moves so much and it’s handy to have a few sets on hand during oil filter changes in case the adapter moves.

Highly recommend this upgraded gasket. The original gasket was not reinforced like this one and it failed. Lost oil pressure and had to do a single engine landing. This seal is far superior.

Stopped the pesky leak that was present when using the copper crush gasket.

I purchased my oil filter conversion kit several years before the first gasket became available. It was plagued with small leaks, I believe because the copper crush gaskets would further crush when the oil filter was torqued. I was very pleased when the filter kit guys gave me one of the first gaskets at Oshkosh when I complained of the problem. It completely eliminated any leakage on my installation. When I first saw the SB to replace the gasket with the copper crush ring, I hesitated as long as I could and was very happy to find they had developed a new gasket resistant to cracking and approved for the SB.

Little pricey haven’t tried it yet hopefully it stops the constant leaks

I had my F&M oil filter adaptor properly installed with the permissible two AN900s. I found that it is almost impossible to remove the old oil filter without moving the adaptor requiring that it be completely reinstalled. I am hoping that the additional friction of this gasket will allow me to remove the filter without moving the adaptor next time.

Super service by Alaska branch of Aircraft Spruce. ST-07 gasket kit fulfills AD requirement.

Required for AD 2022-4-4 for replacing the oil filter adapter lower fiber gasket. Download the process for the installation of the gasket from the Tempest website because it involves a precise way of doing it without damaging the fiber gasket. ST-07 also comes with the upper copper crush washer.

Ill give it 5 stars if it doesnt leak....Just installed it on a customers O-300 and it seemed to be a better torque on the seal that the AN900s. To me it felt as if the threads bottomed out and that was the torque. But this felt much better. So well see if it leaks or not.

Going to try their new gasket )
