1/4 outlet to 3/8 inch quick connect?

My Ryobi pressure washer has a 1/4 inch outlet (non-quick connect). Pretty much all chemical injectors have a 3/8 inch quick connect inlet. But I can’t find a quick connect adapter for my pressure washer because it’s not a 3/8 inch outlet. So I guess I need to find a 1/4 inch to 3/8 inch quick connect adapter, which i haven’t been able to.

Please help.

Your best bet is to get another pressure washer


Not sure what your machine looks like but you may need to adapt the threads, then attach a QC to it

You want your machine to lead with a male

You can find a 3/8" to 1/4" fitting here.

Part#5405-6-4. It should allow you to connect 1/4" to 3/8" quick-couplers or plugs for interchangeable use.
