The fitting has a fitting housing, and a tubular holder for a sensor that is guided in the housing linearly between two positions. The sensor determines a physical and/or chemical process factor in a process. A sealing bush (6) exhibits a circulating groove for receiving sealing rings (7a-7c), where the sealing bush and the housing are made of a plastic and metal, respectively. The sealing bush is dimensioned to position in the housing, to guide the holder parallel to a longitudinal axis between the two positions, and to seal an inner space of the housing in each position against the process. |
