1. A fluid coupling comprising(a) an insertion component extending along an axis, said insertion component including a front region, a first oblique region extending outwardly away from said axis in a direction away from said front region and a second oblique region extending inwardly toward said axis in a direction away from said front region;
- (b) a socket component sized to receive said insertion component; and
(c) a resilient wall metallic annular seal having a configuration defining, in cross-section, (i) a first lip sealingly engageable with said socket component, (ii) a second lip sealingly engageable with said insertion component first oblique region and (iii) a connecting section connecting said first lip to said second lip, said connecting section yieldingly supporting said first lip and said second lip for movement from a first spaced apart position when said insertion component is disengaged from said socket component to a second spaced apart position closer together when said insertion component is engaged to said socket component, movement of said insertion component into said socket component causing said second lip to engage and slide relative to said first oblique region and to become sealingly engaged to said insertion component.

Abstract
A quick-fitting pipe union is proposed with an insertion component, a socket component and at least one sealing element. The sealing element (7) excels by virtue of the feature that it comprises a connecting section (9) and two lips (11) that extend outward from the connecting section (9).

9. A pipe union assembly comprising
(a) a male insertion component having (i) a front section extending along an axis; -
(ii) a first oblique region extending rearwardly from said front section and tapering outwardly away from said axis;
(iii) a second oblique region extending rearwardly beyond said first oblique region and tapering inwardly toward said axis;
(b) a socket component sized to receive said male component, said socket component including a receiving end, an inwardly facing annular recess spaced axially said from said receiving end in a position to overlie said second oblique region when said male insertion component is fully engaged in said socket component, an inwardly facing annular groove spaced axially from said receiving end beyond said annular recess, said annular groove having a bottom;
(c) a retaining element receivable in said annular recess and engageable with said second oblique region for retaining said male insertion component engaged to said socket component; and
(d) an annular metallic sealing element positioned in said annular groove, said annular sealing element in cross-section having first and second resilient lips joined together at a connecting section, said resilient lips being deformable for movement of one toward the other upon axial movement of said male insertion component into said socket component, said first resilient lip sealingly contacting said groove bottom and said second resilient lip being urged closer to said first resilient lip by said first oblique region and becoming sealingly engaged to said first oblique region. - View Dependent Claims (10, 11)
