A pressure washer hose wears out long before the machine does: it gets dragged over block paving, kinked round corners and left out in the frost. This page lists the replacement hoses we can find that fit, from 6m Bosch AQT hoses to Karcher's 10m anti-twist hose for the K2 to K5 and 15m reel hoses for HD and XPERT pro machines.
Need more reach rather than a new hose? See our pressure washer extension hoses, or the hose connectors and adaptors if your fittings don't match. Every hose is sold by My Tool Shed.
Pressure washer hoses are not universal. Each brand uses its own fittings, and even within one brand the hose depends on the age of the machine and whether it has a built-in hose reel. Get these three things right and the hose will fit:
Then match the hose length to the job and check the hose's maximum pressure is at least the machine's top pressure. A hose rated lower than the pump can split.
Most people looking for a Karcher hose own a K series machine, so here's how the Karcher replacement hoses on this page split up:
For a K2 made from 2009 (K 2 Classic, K 2 Power Control, K 2.850 and similar) the H10 Q is the direct replacement and gives you more reach than the short hose most K2s come with. For an older K2, use the HK 7.5 or HK 12 kit. See our Karcher K2 page for the machines and the accessories that fit them.
Check for a reel first. A K4 without one (K 4 Classic, for example) takes the H10 Q or the 9m hose. A K4 with an integral hose reel, such as the K 4 Premium Power Control, takes the 10m reel hose instead. Our Karcher K4 guide covers the full range.
Karcher's HK kits are the easy way to bring an old K series machine up to date. The HK 7.5 gives you a 7.5m hose and a new gun; the HK 12 adds 12m. Both clip into the machine through the supplied adaptor, so later Quick Connect accessories fit too. Neither is made for machines with a hose reel.
Every hose on this page side by side, from the listings. Prices move day to day, so these are bands, not exact prices.

The Bosch 6m hose replaces the hose on EasyAquatak, UniversalAquatak and the AQT 33-10, 33-11, 35-12, 37-13, 40-13 and 42-13. It push-fits at both ends with no tools and is made to resist twisting. Bosch's own listing gives the same model list, part number F016800360. For the machines themselves, see Bosch pressure washers.
The Draper APPW11 is the genuine replacement for the PPW900. Petrol machines run harder than most electric ones, so use the maker's hose rather than a generic one. More on the machines in our petrol pressure washers range.
Professional Karcher machines use two connection types. Older ones have a traditional M22 x 1.5 screw lock; newer ones use Easy!Lock, a quick thread that Karcher says is up to five times faster to connect than a normal screw thread (see Karcher's EASY!Force trigger gun page). The two don't mix without an adaptor, so check your gun and machine outlet before you buy. Hot water HDS machines need a hose rated for heat: the Easy!Lock hoses here are rated to 155°C. Our Karcher professional pressure washers page lists the HD and HDS machines.
A replacement hose takes the place of the hose that came with the machine and runs from the machine to the gun. An extension hose joins on to the existing hose to give you more reach, usually through a connector. If the old hose is split, leaking at the crimp or badly kinked, replace it. If it's fine but too short, an extension is cheaper. The trade-off is that every joint is one more place to leak, and a very long run of jet wash hose can lose some pressure at the nozzle. If you often need more than 10 metres, a longer replacement hose is neater than stacking extensions. Our extension hose page has the add-on options.
A third kind is the drain and pipe cleaning hose. It fits on the trigger gun in place of the lance and has a jet nozzle that pushes itself along a blocked drain or gutter downpipe. A pipe cleaning hose doesn't replace your high pressure hose, so you still need a sound one to run it.
Most hoses die from damage, not age. A few habits make yours last:
Never tape or patch a split high pressure hose. It is carrying water at well over 100 bar, so a repair can burst in your hand. Replace it.
No. Fittings differ between brands (Karcher Quick Connect, Bosch push-fit, M22 screw threads) and between old and new machines. Some third-party hoses come with adaptors, but the safest choice is the maker's own hose for your model.
No. A garden hose only feeds water into the machine. It isn't built for the pressure the pump makes and would burst between the pump and the gun.
If the hose clicks into the machine and into the gun without screwing, it's Quick Connect. K series machines made from 2009 have it. If the hose screws on at the machine, it's an older model: use an HK upgrade kit or an adaptor.
A little, over very long runs, because of friction in the hose. Within the lengths sold for home machines (up to about 15m in total) you won't notice much difference.
Replace it if you see a bulge, a split, bare braid, cracks near the ends, or it leaks at the crimp. Leaks at the clip are often just an O-ring.
Not with a straight replacement hose for a Quick Connect machine. The HK 7.5 and HK 12 kits include a gun because older guns don't take the new hose. Spare guns and lances are on our guns and lances page.
Not sure which machine to buy next? Our K2 vs K3 vs K4 vs K5 vs K7 comparison and the full pressure washer accessories range are good places to start.
