Lenflex R1 single wire braid Pressure Washer Hose - 3/8" - 4,000 psi - Grey non-marking

One wire in 3/8" gives you full flow at 4,000 psi with a lot less weight on your arm than a two wire. If your machine tops out at 4,000 psi there is no reason to carry the extra braid.

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

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 4,000 psi (276 bar), and your pump wants to sit comfortably under that rather than right on it
• Running hot water? Rated to 100°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 can spike well above the machine's rated pressure. This hose is good for 4,000 psi continuous - check what your unloader actually does before you go smaller.
• Most hoses die at the ferrule, not in the middle. The failure is almost always a fold 50 mm behind the fitting from dragging the hose round a corner. Bend restrictors on both ends are the cheapest life extension you can buy.
• Do not coil tighter than about 150 mm radius. Tight winding work-hardens the wire braid. Use the reel, not your elbow.
• Swivel on the gun, male on the machine. That is what stops the hose corkscrewing as you work around the job.
• Never clamp-repair a burst wire hose. Once the braid lets go the length is scrap. A barb and clamp on 4,000 psi water is a genuine injection-injury risk.
• Long runs cost you pressure. Budget roughly 5% loss per 15 m at full flow. If the gun feels soft at 60 m, that is the hose, not the pump - step up a bore rather than winding the unloader.
• UV is what kills the cover. Store it on a reel out of the sun and you will get roughly double the life of one that lives in an open ute tray.
