I present to you “The Air Flusher”.

A simple model to connect together a Air Line Quick Connector( ¼" threads) to a Watering Hose Quick Connector(¾" threads).

I created this “tool” to simply be able to blow out the watering hose and my pressure washer before storing them away before the colder seasons of the year.

I added two variants of it where the second one has ½" threads if you want to add a valve to it.

You will require to buy the quick connectors and/or a ball valve to use this.
 

Enjoy!
