Ranging from rubber hoses to thermoplastic hoses and even Polytetrafluoroethylene (PTFE)-core hoses, hoses of various structural designs are available to meet the demands of virtually any fluid power application. This means that any distributor can source hoses of every specification from a single supplier—LOMOFLEX, a hose manufacturer based in China. Furthermore, we manufacture precision-engineered, high-quality crimp fittings and tooling. This enables our customers to also procure complete hose assemblies directly from the LOMOFLEX hose fitting facility. We specialize in designing custom hoses and fittings tailored to the specific needs of particular industries—such as high-pressure water jet cleaning, sewer cleaning, and jet washing operations.

The application scope for hydraulic hoses is vast. These specialized hoses are primarily utilized within hydraulic systems to convey pressurized fluids, thereby facilitating the transmission of power. In scenarios requiring the movement of loads or directional traction, hydraulic hoses play an indispensable role. Employing hydraulic systems to execute load-moving tasks offers numerous distinct advantages.

When selecting hydraulic hoses, several critical factors must be carefully considered: the operating environment, working pressure, operating temperature, and physical dimensions. Given the wide variety of hydraulic hoses available on the market, selecting the product best suited to the specific application is of paramount importance. It is crucial to note that environmental factors—such as UV radiation, ozone, chemical agents, and saltwater—can potentially damage hydraulic hoses; therefore, the appropriate hose type must be selected based on actual operating conditions.

For instance, underground operating environments necessitate hydraulic hoses equipped with flame-retardant properties and anti-static coatings. Flame-retardant and heat-resistant hydraulic hoses provide effective protection, not only safeguarding equipment but also ensuring the safety of operators and maintaining the continuity of production operations.

Hydraulic hoses are manufactured using a diverse array of materials, commonly including rubber, thermoplastic polymers, and PTFE (Teflon). Quick-disconnect couplings, meanwhile, offer exceptional convenience; they allow for connections to be established without the need for specialized tools and feature automatic sealing capabilities upon disconnection. Some quick-disconnect couplings consist of a male component and a female component—the male component is typically referred to as a "plug," while the female component is known as a "socket." Additionally, three-way couplings are available, enabling the interconnection of three separate fluid lines. When selecting hydraulic hoses, close attention should be paid to the following key factors:

 

Size:

The inner diameter of a hydraulic hose must be selected with precision to ensure the fluid achieves the optimal flow velocity. A flow velocity that is too low will directly compromise system operating efficiency, whereas a velocity that is too high can lead to excessive pressure drops, hose damage, and leakage issues. It is recommended to consult a flow rate chart to identify the hose inner diameter that best matches the specific flow requirements of your operating conditions.

The fluid power industry commonly employs the "dash number" system (also known as "dash size") to designate hose and fitting specifications. This number corresponds to the hose's inner diameter, expressed in increments of 1/16 of an inch. To determine a hose's specifications, check the markings printed on the hose body; if these markings are worn or illegible, the hose must be cut to allow for a direct measurement of the inner diameter. Before cutting a hydraulic hose, ensure you have accurately measured the total required length and the necessary angle for fitting installation.

Temperature:

When selecting a hydraulic hose, it is essential to consider both the *medium temperature* (the temperature of the fluid being conveyed inside the hose) and the *ambient temperature* (the temperature of the surrounding environment in which the hose operates). You must ensure that the temperature rating of the selected hose meets or exceeds the *higher* of these two temperatures—either the medium temperature or the ambient temperature—within your specific application. Furthermore, the type of fluid medium must be taken into account, as different fluids can have varying degrees of thermal impact on the hose material. This is why hydraulic hoses are assigned different temperature ratings tailored to specific fluid types.

 

Application:

Prior to selecting a hydraulic hose, it is imperative to consider the intended purpose of the hose assembly. Specific applications typically require specific types of hoses. If the installation space is confined, the *bend radius* becomes a critical selection criterion. We offer a comprehensive range of hoses featuring bend radii that are half the standard values ​​specified by SAE, yet remain fully capable of operating at full SAE-rated pressures. Relevant industry standards establish clear specifications regarding hose construction, dimensions, manufacturing tolerances, burst pressure ratings, and impulse cycle life.

 

Medium:

The hydraulic hose you order must be fully compatible with the fluid medium being conveyed. This compatibility requirement extends beyond just the inner tube to include the outer cover, the hose fittings, and any O-rings used in the assembly. Please consult a chemical resistance chart to select a hose assembly that is compatible with the specific fluid medium utilized in your system. Pressure:

It is crucial to understand the system's operating pressure, as well as any surge pressures or pressure spikes. When selecting a hydraulic hose, ensure that its nominal maximum working pressure is equal to or greater than the system's maximum pressure, including any surge pressures or transient spikes. Pressure ratings for the most commonly used hoses can be found in the hose overview tables. Unless otherwise specified, all hydraulic hoses comply with industry-standard specifications utilizing a 4:1 design factor. The hose's burst pressure rating is intended solely for manufacturing testing purposes and does not indicate that the product may be used at pressures exceeding its nominal maximum working pressure. When selecting a hydraulic hose assembly, it is essential to consider the "weakest link" within the assembly. The pressure rating of a hydraulic hose assembly is defined by the maximum working pressure of the component with the lowest pressure rating.
