ABSTRACT:
A novel fluid coupling and seal assembly. The assembly includes a coupling body 12 having generally concentric first and second bores 36,38 of greater and lesser diameters, respectively, the first bore also being provided with a generally cylindrical groove 44. A resilient retainer 14 is assembled within the generally cylindrical groove, the retainer having a plurality of prongs 52 which extend inwardly and towards the second groove. A seal assembly 16 is disposed within the coupling body between the retainer and the second bore, the seal assembly including an O-ring 60 formed of an elastomeric material and a tearable diaphragm 64 integral with and of the same material as the O-ring and capable of blocking the passage of fluid through the O-ring prior to the insertion of a fluid line 24. The fluid line which is adapted to be associated with the coupling is provided with a flange 26 which is engaged by the free ends 58 of the resilient prongs to hold the fluid line within the coupling assembly.
