Vehicle air conditioning system`s coupling seal for providing sealing between male and female couplers, has side faces defining maximum thickness of retainer, and annular face sealing lobes protruding axially beyond side faces

摘要

The seal (20) has a retainer (22) comprising opposite axial side faces (34, 36) defining a maximum thickness of the retainer. Radially inner and outer annular sealing elements (24, 26) made of elastomeric material e.g. ethylene propylene rubber, are integrally joined to the retainer. The inner sealing element (24) has annular face sealing lobes (50, 52) protruding axially beyond the opposite axial side faces of the retainer, and a radial sealing lobe (54) protruding radially inwardly from the annular face sealing lobes.
