The connection between the spray handle and the high-pressure hose on my LAND LHP12160H pressure washer will not stop leaking. I replaced the O-ring on the hose, but it still leaks. Is that the only washer in the connection?

For the LAND LHP12160H, the high-pressure hose connection typically relies on a single O-ring at the tip of the hose connector to create a seal inside the spray gun inlet. If you have already replaced this O-ring and the leak persists, please consider the following possibilities:Check for Debris or Damage: Inspect the inside of the spray gun's female connector. Even a small amount of grit, sand, or a hairline crack in the plastic housing can prevent the O-ring from seating properly.Verify O-ring Seating: Ensure the O-ring is seated in the specific groove on the hose end and is not being pinched or twisted when you insert it into the gun.Connection Tightness: The manual notes that the spray gun uses a "cross buckle" or quick-connect style connection. Ensure the locking mechanism is fully engaged and clicked into place. If it is a screw-on type, ensure it is tightened firmly by hand; however, the manual specifically mentions that brass connection adapters include built-in rubber gaskets to minimize leaks—check if your specific model uses an adapter between the hose and the handle that might require its own internal gasket.Lubrication: Applying a small amount of silicone grease (not petroleum jelly) to the O-ring can help it slide into the gun inlet without catching or tearing, ensuring a better seal.If the leak is coming from the handle itself rather than the junction point, the internal valve of the spray gun may be damaged, in which case the spray gun assembly would need to be replaced.
