Karcher HP7 Pressure Hose

A hose looks like nothing but a piece of tubing, but it's actually two things: the path that carries suction or solution, and the seal that keeps it from leaking out along the way. When it cracks, splits, or collapses inside, you get lost pressure or lost pickup, and it's the kind of problem that hides — everything looks fine from the outside while performance quietly drains away.

This is the genuine Karcher OEM HP7 Pressure Hose, part number 6.392-978.0, brand new in the box. Genuine hose means the right inside diameter, the right wall thickness, and the right fitting on both ends.

Length: 28 feet. Hot water rated up to 311 degrees. Use in conjunction with TL7 hose.

Chasing a suction or flow problem you can't find? Run your hands down the hoses first. Cracks and soft spots love to hide on the underside.
