FIELD: machine building.
SUBSTANCE: present invention relates to fittings with housing (1), in which seat (6) is located. Shutoff body (3) is arranged to be moved by element (5). Element (5) is at least partially surrounded by guide bushing (9). Guide bushing (9) is connected to seat (6). On seat (6) there is sealing element (7). Seat (6) has recess (17) for sealing element (7). Sealing element (7) is connected with seat (6) with geometrical closure. Joint is implemented due to an undercut.
