No, these adapters are strictly for the water inlet side of the pressure washer where you connect your garden hose. They cannot be used on the high-pressure outlet.

Rinse the adapters with clean water after each use and allow them to air dry before storing. Avoid using abrasive cleaners.

Yes, the kit is designed to connect to standard garden hoses. The yellow adapter connects to your garden hose, and the black adapter connects to the pressure washer's water inlet.

Quick Connect allows for fast, tool-free attachment and detachment of your garden hose to the pressure washer, saving time and effort during setup and takedown.

Ensure the hose and pressure washer connectors are clean and free of debris. Check that the O-ring on the garden hose connector is properly seated and not damaged. Push firmly until a click is heard.

Verify that the O-ring is present and in good condition on the garden hose connector. Ensure the connection is fully seated. For threaded connections, ensure the thread is not cross-threaded and is securely tightened.

Ensure you are pulling the collar back completely before attempting to detach the hose. Clean the connection area if dirt or debris is obstructing the mechanism.
