Pressure washer connections

Will this hose fit your pressure washer?

Check the connection at the machine or spray gun before you buy. A fitting that screws on can still leak if the seal size is wrong.

Know the difference: M22 14 mm vs 15 mm

Both can have the same outer threads. The inner seal diameter determines whether the connection seals. If you cannot confirm that measurement, the safe result is “more information needed.”
