<p>The proposed pressure-tight joint of piping parts has its internal part (2) arranged inside a piping external part (3). Between those parts (2, 3) there is arranged a packing (1) having the form of a ring of elastic material and consisting of a locating arm (11) fitting flat to a wall of one from the parts (2, 3) and a sealing arm (12) that in free state projects toward the other part (3, 2). The packing (1) free state cross section is L-shaped and the locating arm (11) thereof fits flat to a bottom of a circumferential recess (21) being performed in one of the piping parts (2, 3) on its side turned toward the other piping part (3, 2) and whose depth is greater than the sum of thickness of the packing (1) arms (11, 12) in free state thereof.</p> |
