Hey guys, my brother just received a free Snap On 1650 Pressure washer. I let him have one of my foam lances for it.

The issue is, my gun has m22 threads, and I'm not sure what size the snap on hose is. I feel like it's 3/8.
I know snapon, like karcher, have their odd sizes... Their Customer Service was unable to tell me what type of thread it was...



Can anyone confirm this for me, before I go tell him what adapter to get?



Thanks
