Swivel Connector for long hose

The long extension hose needs a connector / adaptor to connect to the cannulas, etc.
Usually this is done with a fixed adaptor like this one

However, I prefer this swivel connector because it helps prevent the hose from tangling, so we offer it as an optional upgrade.
