3M Suction Hose for Karcher K2-K7 & Bosch AQT

Highlights

This 3M suction hose kit brings reliable water intake to compatible pressure washers, combining a quick coupling and a mesh filter with a three-layer hose construction for everyday cleaning tasks. It suits gardeners and home users who want a straightforward way to draw water from a tank or barrel without relying on mains supply, and it keeps coarse debris away from the pump.

Why it’s worth it

The hose’s layered build improves tensile strength and resists tangling, which helps during repeated use around the garden. The stainless steel 50-micron filter captures grit and particles before they reach the washer, helping to protect the pump. The quick coupling makes attachment to the inlet straightforward, and according to the manufacturer the hose material has been upgraded to be less prone to cracking in cold or hot conditions. Bear in mind that connectors must be hand-tightened to ensure a good seal.

How to use it

Assemble the included parts by hand, tighten each connector securely and prime the hose if necessary. If the hose is stiff after storage, soak it in warm water for one to two hours to restore flexibility. You’ll notice faster setup compared with makeshift suction solutions, and the filter reduces the chance of blockages.

What you get

The pack contains the suction hose, quick coupling fittings and the stainless steel filter. All parts are supplied for self‑assembly and no special tools are required.

Who it suits

It’s a good fit if you need a practical, durable suction option for compatible Karcher or Bosch electric pressure washers and prefer the convenience of a quick coupling and built‑in filtration. It may not suit users requiring bespoke lengths or fittings different from those supplied.
