Shop high pressure hoses built for commercial pressure washers. We carry Kärcher pressure washer hoses from short 3' lengths to 150' runs, rated from 1,800 to 6,000 PSI, including gray non-marking hoses that won't streak concrete, shop floors or wash bays. We've been helping customers match the right hose to their machine for over 60 years.

The best pressure washer hose is the one that matches your machine's pressure, fittings and how you work. Check these six things before you order.
A hose's working pressure must meet or exceed your pressure washer's maximum PSI. An underrated hose can burst at the crimp or along the braid, and that's a major safety hazard. For machines up to ~3500 PSI, a 4000 PSI hose gives you a safe margin. For 4000 PSI-and-up machines, hot water units or all-day use, step up to a 6000 PSI hose. NOTE: A higher-rated hose won't raise your cleaning pressure, but will usually last longer under hard use.
25 feet: For close-range work, cart-mounted units and tight spaces. Easy to coil and store.
50 feet: The most popular length. Enough reach to work around a vehicle or other equipment without moving the machine.
100+ feet: Fleet washing, large lots, agriculture buildings and industrial sites. Pair long hoses with a hose reel to prevent kinks and trip hazards.
Short jumper hoses (3'-10'): Connect a pump to a reel or a reel to a wand.
Every foot of hose adds a slight pressure loss, so buy the length you actually need, not the longest one available.
A 1/4" pressure washer is lighter and easier to handle but restricts flow, which suits lower-GPM residential machines. A 3/8" pressure washer hose is the standard for commercial machines because it moves more water with less pressure loss, especially on 50' and longer runs. High-flow industrial systems may call for 1/2".
Pressure washer hose fittings aren't universal, so check both ends before you buy:
Hot water pressure washers need a hose rated for hot water. A cold-water hose can soften, blister and fail at high temperatures. Check the maximum temperature on the product against your burner's outlet temperature, leaving some margin.
A steel braided pressure washer hose has one or two layers of wire reinforcement under the cover. Single-wire hoses are lighter and more flexible and generally use up to around 4000 PSI. Double-wire hoses handle 5000-6000 PSI and hold up better to dragging, crushing and daily commercial use.
