Even with the best intentions, stuff happens: the spray gun that went into the garage in one piece comes out broken. All the wear and tear adds up over time.
If your spray gun is just worn out, we recommend getting one of our spray kits. The spray gun, hose, and lance all fit together perfectly and will wear evenly.
If you need just the gun, then it's all about the connectors. When you visit the link at the bottom of this page, click on a spray gun and you'll find specs and features detailing what kind of connectors the gun has and which pressure washer models it's compatible with.
