Pressure Washer Nut

This goes over the nut. If your plastic thing that looks like this is broken or unusable, this is a perfect replacement.

For 25mm nuts.
- 33mm outer diameter for adjustable
- Knobs for hand turning

used on most pressure/power washers

there is a slight draft angle which helps put the nut on. the bottom where the knobby bits are face the end of the hose/ where you want to connect. so when you push it on, it gets progressively tighter around the nut.
