ABSTRACT:
A fluid coupling assembly includes a rotatable fluid coupling and fastener, and a gasket having upper and lower washers interconnected by a deflectable strap. When the strap is laterally deflected, the fastener passes through openings in the coupling with minimal interference. The strap exerts a return force for engaging the washers with the fastener upon release. Tangs on the washers engage the fastener, and one washer forms a seal against a surface. A banjo joint assembly includes a rotatable banjo coupling, the gasket, a gasket with tangs, and a bolt retained to the coupling by the tangs. A method for preparing a fluid coupling assembly for attachment to an external surface includes providing a gasket with deflectable portions, positioning a fluid coupling in the space therebetween, deflecting the portions sufficiently to insert a fastener into the coupling, and retaining the coupling on the fastener when the portions are not deflecting.
