Looking for help finding a replacement stainless pressure washer quick connect fitting.

Just received my BOSS Foam Gun, but found out the fitting they provided doesn’t fit my Ryobi pressure washer wand. Long term I’m planning on upgrading the hose/wand like Zach discusses in his thread, but short term I just need to make it work with the factory setup.

The problem:



You can see where the fitting is too deep, preventing it from locking into the wand.

The problem I’m running into looking online is that so many places don’t have good straight side views of the fitting, and no one has any measurements to compare to. I don’t want to order a $7 fitting, wait 5 days for it to show up and be wrong. The other challenge is that I’d like to get a stainless fitting to match the gun, since i don’t know how long term this will be.
