ABSTRACT:
A connector for delivering combustion gas to a gas fired appliance from a stationary supply line where the appliance moves toward and away from the supply line with the connector straightening and flexing between them as the appliance moves. The connector comprises a flexible hose assembly and first and second swivel fittings at respective hose assembly ends. Each swivel fitting defines a gas flow path and comprises a swivel member for communicating the connector with the appliance or the supply line. The hose assembly comprises a flexible metal hose member antitorsion fittings forming ends of the hose assembly connected to respective swivel fittings. The antitorsion fittings comprise pintle and nipple members rotatable relative to each other to prevent torsional stress in the hose member when the appliance moves relative to the supply line.
