Abstract: A fluid connector in a fluid joint assembly such as in a machine hydraulic system includes a connector body having a stem with a seal face extending circumferentially around a connector axis at a backup sealing location. A non-metallic seal is upon the stem and extends circumferentially around the connector axis at a primary sealing location. The fluid connector also includes a swivel nut including threads and a snap retainer and supported for rotation upon the stem. The fluid connector can establish a primary sealing state by way of hand installation, and can be torqued to a backup sealing state to provide a robust metal-to-metal seal.
