Overview

Tempest Gasket Kit ST-07

Stratus Tool Technologies ST07 is a multi-layer gasket designed to combine the enhanced anti-leak characteristics of the FM07 fiber gasket with the resiliency and resistance to sudden rupture of the AN900-28 copper crush washer. The outer facings of this new gasket are comprised of an expanded PTFE matrix that provides better conformance to sealing surface imperfections. The perforated stainless steel core is embedded within the ePTFE to enhance stability and increase blowout resistance. Laboratory and flight testing have confirmed that this new gasket eliminates the nuisance oil leaks some operators have experienced when replacing FM07 fiber gaskets with AN900-28 copper crush washers in compliance with AD 2022-04-04 and Stratus Tool Technologies SB-001 Rev. B.

    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.

    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.

    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.
