Selecting the Right Pressure Washer Hose

Selecting the Right Pressure Washer Hose

Pressure washer hoses use pressurized jets of water to loosen and remove dirt, grime, oil, grease and other contaminants from equipment and surfaces. They can handle high working pressures as well as extreme temperatures.

Choose a flexible yet durable hose capable of withstanding regular use without kinking and abrasion, and select fittings which match the threading size and type of your machine threading threadings.

Working Pressure

Working pressure refers to the maximum operating pressure rating for any given hose or tube. It’s crucial that this working pressure matches up with dynamic and static pressures experienced in your application; otherwise it could cause failure, leaks and safety hazards that require replacement of that particular product.

There are various factors involved in determining a hose’s rated working pressure, including temperature of media being run through it, environment in which it will be used and vibration or pulsing effects which may cause fluctuations in working pressure of hose.

Manufacturers typically mark a hose’s working pressure, although this typically only refers to its individual pressure rating and not that of its assembly as a whole. This is because fittings and clamps used can affect its working pressure; for example a high pressure air hose connected with light duty radiator clamp will likely fail under its stated working pressure rating.

Bursting pressure refers to the maximum short-term internal peak pressure a hose can tolerate before succumbing to catastrophic failure, typically four times or higher than its working pressure. It serves as a safeguard against sudden pressure spikes or system malfunctions which could otherwise cause it to fail catastrophically. A bursting pressure should not necessarily reflect long-term reliability and performance as its level may change with use over time.

Burst Pressure

Selecting the optimal pressure settings for your garden hose is essential to its safety and longevity. A properly maintained, high-quality hose can serve you for years if maintained well and is worth investing in. When selecting your pressure hose it is important to take into account your gardening tasks as well as equipment needs; burst pressure should also be considered in making your selection decision.

Burst pressure refers to the short-term peak pressure a hose can withstand before structural damage occurs and it ruptures, typically well beyond the working pressure range to ensure safety and prevent catastrophic failures. Bursting pressure depends on several factors including its construction material, reinforcement layers, inner/outer diameter dimensions as well as temperature of fluid being carried in it.

Working Pressure (WP) refers to the maximum continuous pressure a flexible hose can endure without incurring structural damage or leakage during its lifespan, determined by its thickness and strength. Exceeding it could result in damage, degradation and premature burst if exceeded; failing this threshold could result in increased structural failure as well as premature bursting.

The maximum working pressure of a flexible hose typically equals four times its minimum bursting pressure or proof pressure; this indicates it has undergone an integrity and safety test to verify its operation and integrity.

Hotsy Water Blast offers pressure hoses that have undergone rigorous proof tests and are certified for 3,600 psi pressure levels, so we highly advise following manufacturer recommendations by regularly inspecting for signs of wear or degradation, such as signs of wear or degradation in your hose’s casing or spray pattern, while keeping it cool and dry at all times.


Pressure hoses transport materials under internal pressure in a controlled fashion from one location to the next, requiring greater care than more rigid forms such as pipes in terms of handling.

Most hose manufacturers provide a selection of sizes, working pressures and diameters. Your choice will depend on the application and cleaning needs for your system; while diameter determines flow rate which can influence water pressure.

Common pressure washer hoses include small (1/4″) ones intended to operate at up to 3,200 PSI for consumer-grade electric or gas pressure washers, while larger industrial-grade versions can handle much higher pressure levels. No matter your application, ensuring proper length and routing is key to ensure safe use of the pressure washer.

As a general guideline, an extended hose will lose approximately 2.5 percent of pressure per 100 feet it extends – this should provide sufficient cleaning power for most tasks while adding weight that could become burdensome to transport around a job site. However, extended hoses also mean more weight to drag around.

Proper hose routing is essential to ensuring no part of the hose is pulled, kinked, or crushed, while assemblies must also be secured with clamps to keep them from rubbing against other components and to minimize movement and strain on fittings. Swivel ends can help extend the lifespan of assemblies while decreasing repairs or replacement needs.


Material selection for pressure washer hoses is of great significance in their operation, as this determines their durability and flexibility. When purchasing one of these components, ensure it’s made from strong yet flexible materials which can withstand damage caused by harsh cleaning chemicals, water pressure fluctuations, extreme temperatures or other environmental elements. Kink-resistant structures will help maintain continuous waterflow without interruption to your work activities.

Professional-grade pressure washer hoses typically made of PVC plastic, rubber, or polyurethane are constructed for heavy-duty jobs like car washing or general cleaning. PVC plastic hoses are the most widely used variety, as they can handle high water pressure while being less flexible than rubber or polyurethane options; PVC plastic is commonly preferred because of its ability to hold high water pressure without losing flexibility compared to rubber industrial hoses; they’re best for light duty such as car washing or general cleaning tasks. Rubber industrial hoses offer greater resistance against abrasions cuts cuts chemicals while being more flexible than PVC plastic options while being more resistant than PVC plastic versions in terms of water pressure handling capabilities as well as being better able to hold higher water pressure levels than their counterparts when exposed to colder environments than other forms.

Working pressure of a hose is determined by its combined working pressure of its components – including the hose, fittings and end connections. When selecting a hose it is important to consider its maximum pressure rating as this will impact on whether or not your desired working pressure can be reached. When selecting fittings and end connections for your hose it is also advised that threading size of each component be compatible as poorly connected hoses may rapidly leak or even be damaged due to exposure to water or chemical contaminants.


Pressure hoses are used to transport pressurized fluids, and must be capable of withstanding significant amounts of pressure. Selecting fittings that will protect the hose from damage, reduce friction and energy loss, and ensure safe, secure connections are crucial in order to ensuring its smooth functioning and safe transport. Durable materials that match up well with hydraulic fluid should be selected. Furthermore, selecting appropriate sizes for connections must also be selected in order to prevent malfunctions, damages, or endangering lives – which TT Weber Hydraulic offers an extensive selection of hydraulic fittings so you can find what suits you best!

When selecting a hydraulic hose fitting, there are numerous considerations to keep in mind when selecting one, including port connections, fitting ends and sealing methods. You should also decide between permanent or reusable hydraulic fittings; permanent ones (also known as crimped fittings) require special machines while reusable hydraulic fittings (sometimes referred to as compression fittings) can be easily secured using wrenches and pliers.

To ensure a leak-free connection, it is imperative to clean hose ends and fittings prior to attaching them – this can be accomplished using either compressed air or lint-free cloths. Furthermore, it is also vital that the diameters match perfectly – otherwise collapse may occur, creating unsafe or ineffective connections.

Some applications may require special hose fittings, like reducers or elbows, which allow you to connect a hose of varying diameter to meet specific needs. Other special fittings, such as adapters, can connect thread sizes or types for changing flow directions or adding connections.
