How to Choose a Pressure Washer Hose: A Buyer’s Guide

April 3, 2025 | Nate Cord

Choosing the right pressure washer hose can make all the difference for your cleaning jobs. In this guide, we break down everything you need to know—from what a pressure washer hose is to why you can’t simply swap it with a garden hose and how to choose the right hose for your requirements.

What is a Pressure Washer Hose?

A pressure washer hose is a reinforced, flexible tube that transports high-pressure water from the machine’s pump to the nozzle. Unlike standard garden hoses, these are built to withstand extreme pressure, which prevents leaks or bursts during use.

Can You Use a Garden Hose With a Pressure Washer?

No, a garden hose is not a substitute for a pressure washer hose. Garden hoses can supply water to the pressure washer’s pump but are otherwise not built to withstand the high pressure generated by pressure washers.

In fact, it is dangerous to attempt to use one as it could lead to bursts, leaks, or damage to the pressure washer and its target.

Thus, a hose specifically designed for pressure washers is essential.

Are Pressure Washer Hoses Universal?

So, is there one type of pressure washer hose? Not quite.

Pressure washer hoses are not universally interchangeable between all models. Your hose needs to be compatible with the connection type, such as screw-on or snap-on, and the pressure rating of your machine, measured in PSI.

You also need to consider the length and material of your hose, as we cover below. Keep reading to find out which hose is best for your requirements.

Which Hose is Best for a Pressure Washer?

The best hose for your pressure washer matches the pressure rating, length, and diameter recommended by the manufacturer. But it also depends on what you intend to clean.

1. Pressure Rating

This rating indicates the maximum pressure the hose can handle safely, expressed in PSI (pounds per square inch). Your hose’s PSI rating must exceed your pressure washer’s maximum output so it can handle the high-pressure water without breaking down.

2. Connector Type

Connector types determine how your hose can be attached to the pressure washer and other accessories. Many hoses come with common connector types, such as quick-connect fittings, which are designed to snap on and off. However, some hoses feature threaded or specialised connectors, which limit compatibility with other equipment.

Standard or quick-connect fittings are the most versatile (and universal), but for high-pressure applications, threaded connectors do provide a more secure, leak-proof connection.

3. Length

The hose length should reach all areas you intend to clean without causing a significant pressure drop, i.e. when it is overstretched. Longer hoses can sometimes reduce pressure, so finding a balance between length and performance is crucial.

For infrequent, light to medium cleaning jobs, you’ll tend to have a domestic pressure washer. These have short hoses (3-10m) with low to medium water pressure and flow rates.
Industrial pressure washers for heavy-duty jobs, on the other hand, have longer hoses (10-15m+) with high water pressure and flow rate.

If your work is confined to a small area, a short hose will suffice. However, if you need to extend your reach without moving the pressure washer unit, a longer hose is more practical.

What About Hose Size?

Hose diameter also impacts performance. A narrower hose increases pressure but reduces the flow rate (GPM), which can strain the pump. A wider hose improves flow but may lower PSI.

Small (1/4″) hoses are the most common. However, large (3/8″) hoses are often found on professional models for heavy-duty use.

4. Material

The material of the hose affects its performance and lifespan.

• Rubber Hoses: The most popular option, rubber hoses are kink-resistant and durable in cold climates. They are ideal for heavy-duty use (high-pressure tasks) but heavier and less flexible than thermoplastic.
• Thermoplastic (PVC) Hoses: Lightweight, flexible and affordable, but less durable in extreme temperatures or harsh conditions. Perfect for casual or occasional use in mild, temperate climates.
• Steel-Braided Hoses: Reinforced for industrial use and high PSI (3000+ PSI). Heavier and less flexible than their counterparts, but they are perfect for high-demand jobs in any condition.

If your cleaning tasks are highly demanding or involve rough surfaces, a steel-braided hose is best. For more casual or domestic use where ease of use is required, choose a PVC or rubber hose.

Final Tips

To recap, ensure the hose is compatible with your pressure washer’s PSI rating, fittings, and intended applications. Once you’ve picked a few possible models, customer reviews can offer insight into a hose’s performance and durability in real-world conditions. Additionally, a solid warranty period can give you extra peace of mind.

Once you’ve chosen your pressure washer, looking after it is as important.

• Don’t leave any water in the machine after use.
• Don’t drag the hose on the floor, as this can cause it to fail.
• Always store hoses coiled and away from sunlight to prevent cracking.
• But avoid bending it sharply or coiling it too tightly, as this can cause breakages. Use hose reels or coils to prevent stress on the structure.
• Periodically inspect your hose for signs of wear, abrasions, or leaks.
• Replace hoses showing cracks, bulges, or leaks.
• Pair your hose with the correct nozzle (e.g., a 3.0 nozzle at 25 degrees is best for general-purpose cleaning of pavements, driveways, and patios).
