Ryobi inflator to garden hose adapter, male US GHT (model P738)

This is an attachment for the Ryobi 18-Volt One+ Cordless High Volume Power Inflator (Model P738) to connect a garden hose to the inflator so it can be used to blow out residual water from a hose at the end of the season. 

To use: place the hose flat on the ground (straight or coiled), and blow out water until the outflow is minimal. To use this for more than one hose, quick-couplings make the process much faster than threading on and off each hose from the adapter.
