Hoses and Tubing

Pressure washer setups typically use:

• High-pressure hoses – carry water from the pump to the spray gun
• Supply (inlet) hoses – bring water into the machine
• Chemical/detergent tubing – used for applying soaps and cleaners

Each type is designed for different pressure levels and applications.

Key factors to consider:

• PSI rating – must match or exceed your machine
• GPM rating – ensures proper flow
• Length – longer hoses offer reach but can reduce pressure
• Diameter – affects flow and performance

Choosing the right hose helps maintain efficiency and prevents damage.

The most common pressure washer hose sizes include:

• 1/4″ – light-duty and residential use
• 3/8″ – commercial and industrial applications
• 1/2″ – high-flow or specialized setups

Always match hose size with your machine’s requirements.

Pressure loss can be caused by:

• Hose that’s too long or too small in diameter
• Kinks or bends restricting flow
• Internal wear or damage
• Leaks at fittings or connections

Using the correct hose size and keeping it in good condition helps maintain performance.

You should replace your hose if you notice:

• Cracks, bulges, or visible wear
• Leaks or weak spots
• Reduced performance
• Exposed reinforcement layers

Damaged hoses can be unsafe and should be replaced promptly.

Some hoses use standard quick-connect or threaded fittings, but compatibility depends on size, pressure rating, and connection type. Always confirm before purchasing.
