In the illustrated embodiment, the adapters are threadedly connected to the hose end fitting and service fitting, respectively, and are provided with structure for effecting a quick connection between the adapters and, thus, between the service hose and service fitting. In one embodiment, the hose fitting adapter defines a rectilinear through passage, and in another embodiment, the hose fitting adapter defines a right angle turn flow passage. The hose fitting adapter is provided, in the illustrated embodiment, with a core depressor for engaging an opening in the core valve of the service fitting upon sealed connection of the adapters. The hose fitting adapter may be provided with a shutoff valve which is adapted to be opened by the engagement of the core depressor thereof with the core valve of the service fitting.
