Abstract
A block fitting assembly includes a first block, a second block, and a first sealing element disposed between the first block and the second block. A clamping device applies a clamping force for compressing the first sealing element between the first block and the second block in an axial direction of the block fitting assembly. A first heel structure projects axially from one of the first block or the second block and projects towards the other of the first block or the second block. The first heel structure is configured to be spaced apart from or to contact the other of the first block or the second block depending on a temperature of the first block.
