I recently bought a gas powered 2600 psi pressure washer. It's a Troy Bilt XP series with a Honda motor. I want to buy the Foam Cannon here from Autogeek but none of the pictures of the fitting look like mine. Mine looks similar to an air compressor fitting just with an o-ring and more rounded at the base. Here are some pictures, hopefully someone can point me in the right direction.
