An assembly comprising two components having different thermal coefficients of expansion. Each component is provided with means such as flanges and bolts for securing the components together. At least one of the components is provided with slots in the flange and end portion of the component to impart flexibility thereto. One of the components is provided with a bridging piece which covers the slots to prevent leakage of fluid through the slots, and the bridging piece has a seal that engages the other of the components to form an effective fluid seal.
