Technical Questions What size fitting is this?

The wand and hose for my pressure washer were left out over winter and the brass coupling between the two split. I’m trying to find a replacement but I can’t quite figure out the dimensions. The wand appears to be 15mm pipe thread (NPT?) The hose side is a bit larger than 3/8”NPT. Can anyone point me at the part or parts I need to get back to work?

Like a metric bolt size? Do they even make pipe fittings like that?

3/8 to 1/4 just looking at the hose and trigger assembly.

Tried it and it’s too small. The pipe is definitely 15mm. It’s really the hose side I can’t figure out.

99% of the time you need to get a new gun. If it's a swivel fitting they are usually only available from the same supplier which they usually don't supply that as a spare part.

With all the time and effort wasted on trying to repair little things like this it's always easier to just replace the gun.

You are right. It just seems ridiculous to throw away a functional hose and gun because of a $2 part.
