Abstract

A multi-plane swivel connector for use in attaching a pair of fluid conveying members together, the connector including a pair of swivel portions, that connect together at proximate ends, one end being insertable within the other, a double sealed connection provided at the junction of the connection of the swivel ends together, there being a swivel nut securing externally to the outer end of one of the pair of swivel portions, there being a double sealed connection provided between the said swivel nut and the said contiguous swivel portion, there being a pair of O-rings provided at each of the double sealed connections between the swivel portions, and the connection of the swivel nut to one of these swivel portions, said pair of O-rings at each double sealed connection being of step relationship with one O-ring being of greater diameter than the other O-ring, one of the O-rings being formed of fluoro carbon, while the other O-ring of each double sealed connection being formed of fluoro silicone; and during the formation of the swivel portions, as through their formation as cast metal parts during an injection molding process, the pressures applied during the injection molding process being increased from the moment of injection until rapid cooling of the cast parts occurs, with the increased pressures being applied to prevent dendritic growth of the cast parts.
