Waterblast Two wire ultra high pressure Pressure Washer Hose - 3/8" - 8,700 psi

Eight thousand seven hundred psi. Surface prep, paint and coating removal, concrete cleaning - work where a standard washer hose is nowhere near rated. The red cover is the trade signal that this is a UHP line, not a wash hose.

Choose from the dropdown above. Every length is made up and ready to fit: 3/8" female swivel x 3/8" BSP male.

Ways to buy this hose

• Off the shelf – all 5 lengths below are made up, tested and ready to dispatch
• Every one carries its own part number, so a reorder gets you exactly the same hose
• The cover colours are the same hose inside. The difference is what you are dragging it across
• Want a length we do not list, a different fitting on the end, or both? We make them up here – call us
• Need something to wind it onto? See our hose reels

Specifications

How to choose

• Measure the run, then add ten to fifteen per cent. A hose pulled tight is a hose that gets dragged over an edge
• Check the machine, not the hose. This one tops out at 8,700 psi (600 bar), and your pump wants to sit comfortably under that rather than right on it
• Running hot water? Rated to 155°C
• Cover is a job decision, not a pressure one. Non-marking colours for finished floors and paintwork, dark covers for yards, gravel and anything abrasive
• Not sure the ends suit your machine? Send us a photo of the fitting and we will tell you straight

Technicians Advice

• Rate the hose to the unloader, not the plate on the machine. An unloader dumping to bypass spikes above the machine's rated pressure. This hose is good for 8,700 psi continuous.
• Most hoses die at the ferrule. The failure is a fold 50 mm behind the fitting from dragging the hose round a corner. Bend restrictors on both ends are the cheapest life extension going.
• Never clamp-repair a burst hose. Once the reinforcement lets go the length is scrap - a barb and clamp on 8,700 psi water is a real injection-injury risk.
• Long runs cost pressure. Roughly 5% loss per 15 m at full flow. Soft at the gun on a long run means step up a bore, not wind up the unloader.
• UV kills covers. Stored on a reel out of the sun, a hose lasts about twice as long as one living in an open ute tray.
