High Pressure Quick Release Coupling
Quick coupling for home and garden high pressure washers
Nilfisk Home & Garden High Pressure Washer with M22 Thread Connection on the Device Quick Connector
*Due to the connector being fresh out of the mould, your Nilfisk hose may be a little tight the first few times you use it. This will ease off and become much better. Ensure when inserting the hose it goes fully in until you hear the adapter click, indicating it is inserted correctly and secure.
*If you wish to unscrew the coupling for any reason, ensure the hose is disconnected as the water pressure will not allow disconnect.
