Filter elements and filter assemblies are provided for use at any operating temperatures, having the filter elements disposed in sealing relationship in a leak-tight seal formed at such operating temperature by thermal expansion of at least two sealing components. Thus, at a lower or higher temperature, such as normal atmospheric temperature, the sealing components are contracted, and release the filter elements from sealing engagement, for removal and replacement, while at the selected operating temperature such sealing components are expanded, to form a thermal leak-tight seal therebetween. |
