Function of the Hose

The Centurion 3/4" Pressure Washing Hose helps:

• Deliver a consistent water supply to pressure washers
• Maximize inlet water flow with its large 3/4" diameter
• Reduce the risk of pump cavitation and starvation
• Protect surfaces with its non-marking outer cover
• Provide durable, reliable performance in commercial environments
• Simplify installation with standard garden hose connections

Its FGH swivel fitting minimizes hose twisting during installation and operation, making connections easier while reducing stress on fittings.

Common Signs Replacement Is Needed

Replace the hose if you notice:

• Cracks or cuts in the outer cover
• Bulges or soft spots
• Leaking fittings
• Excessive abrasion or wear
• Kink damage restricting water flow
• Loose or damaged garden hose threads

Replacing a worn supply hose helps ensure proper water flow and protects your pressure washer pump from damage caused by inadequate water supply.

Installation & Service Notes

Turn off the water supply before connecting the hose.

Attach the Male Garden Hose (MGH) end to the water source and connect the Female Garden Hose (FGH) swivel end to the pressure washer inlet or compatible equipment. Tighten fittings securely by hand and check for leaks before operating the system.

Ensure the hose is fully uncoiled during use to maximize water flow and avoid unnecessary strain.

Important: Never exceed the maximum 300 PSI working pressure or 200°F operating temperature. This hose is intended as a water supply hose and is not designed for high-pressure discharge applications.

Maintenance Recommendations

• Inspect the hose regularly for cuts, abrasion, and leaks.
• Check fittings and hose washers periodically.
• Avoid dragging the hose across sharp or abrasive surfaces.
• Drain and store the hose properly after use.
• Keep the hose out of prolonged direct sunlight when not in use.
• Replace damaged hoses immediately to maintain safe and reliable operation.
