O-Ring für Pressverbindungen |
摘要 |
O-ring (1) for press-fittings that in at least one point has a recess with respect to the inner profile of the O-ring; at said recess the O-ring (1) has a cross section (3) modified with respect to the rest of the O-ring. Said modified cross section (3) substantially has a shape that can be obtained from an irregular hexagon having a plane of symmetry (Q-Q'). The presence of the recess makes said O-ring (1) suitable to detect possible leaks caused by lack of pressing, already during the tightness tests, while assuring a perfect tightness of the press-fitting. <IMAGE> |
