FIELD: manufacturing technology.
SUBSTANCE: invention relates to sealing devices. Disclosed is ring gasket (22) arrangement having V-shaped cross-section located in annular groove (24), having cross-section in form of trapezoid, in which smaller trapezium base (30) corresponds to groove (24) cylindrical bottom and which is radially open inside at level of trapezium large base (32), in which gasket (22) has radially outer circular bearing plate (28) and two generally conical annular branches (26), radially elongated inward from bearing plate (28). Each branch (26) Inner radial end rests against axial direction into corresponding groove (24) wall (34, 36). Gasket (22) is installed in groove (24) so, that gasket (22) bearing plate (28) is radially located at certain distance from annular groove (24) bottom.
EFFECT: invention improves connection leak-tightness.
