Inappropriately sized hoses can lead to hydraulic oil leaks or even hose bursts, causing equipment damage and personal injury. A correct understanding and application of hydraulic hose size charts is fundamental to hydraulic system design and maintenance.
Hydraulic hoses come in various sizes, distinguished by their inner diameter (ID) and outer diameter (OD). Common sizes range from 1/4 inch to 2 inches, with larger sizes available for specialized applications.
आंतरिक व्यास
Hydraulic hoses are primarily classified into two categories: metric and imperial sizes. Metric sizes range from 4mm to 25mm in inner diameter, while imperial sizes range from 1/4 inch to 2 inches. These inner diameter specifications are widely used in various hydraulic systems.
According to hydraulic hose inner diameter standards, there are two main methods for calculating the hose inner diameter: one is based on the outer diameter and wall thickness, and the other is based on flow rate and velocity. Calculations based on outer diameter and wall thickness are generally suitable for simpler applications, while calculations based on flow rate and velocity are more scientific and accurate.
The performance of a hydraulic system is closely related to the inner diameter of the hose. Generally, a larger inner diameter results in a larger flow rate but a slower flow velocity, while a smaller inner diameter results in a faster flow velocity. Simultaneously, a larger inner diameter also means lower resistance and pressure drop, while a smaller inner diameter results in greater pressure drop and higher resistance. Therefore, when selecting hydraulic system hoses, it is necessary to choose an appropriate inner diameter based on the actual situation.
Outer Diameter:
The outer diameter is the overall diameter of the hose, including the thickness of the inner tube and reinforcing layers. The size of the outer diameter affects the matching of the hose with the fittings and the required installation space. The outer diameter of hydraulic hoses is typically a few millimeters larger than the inner diameter; this difference depends on the material and number of reinforcing layers used inside the hose. A reasonable outer diameter design ensures sufficient strength and durability of the hose under high pressure.
The outer diameter of hydraulic oil pipes primarily ensures the strength of the oil pipe under high pressure. The larger the outer diameter of the hydraulic hose, the higher its strength and the greater the pressure it can withstand. Typically, the outer diameter is larger than the inner diameter to provide sufficient protection against rupture under high pressure. Generally, the outer diameter ranges from 10mm to 60mm, depending on the system's working pressure. How to select the appropriate inner and outer diameter specifications? This depends on the design requirements of the hydraulic system. Factors such as the hydraulic system's working pressure, working environment, type of hydraulic oil used, and flow rate all affect the selection of the hose's inner and outer diameters. We often see high-pressure hydraulic systems with large inner and outer diameter hoses, capable of withstanding exceptionally high working pressures. Conversely, some low-pressure systems have smaller inner and outer diameters to meet daily flow requirements.
लंबाई:
The working length of a hydraulic hose refers to the distance between the connection points at both ends of the hose, a crucial parameter to consider during installation. Excessive length leads to complex system layout, increased material waste, and installation difficulty; insufficient length may cause the hose to tighten, affecting its service life. Hydraulic hoses can usually be customized to meet specific needs, but when purchasing them, it is best to choose products that are close to the standard length to better suit equipment installation and maintenance.
Other Important Parameters of Hydraulic Hoses

Hydraulic Hose Fittings and Couplings
Hydraulic hose fittings are used to connect hoses to hydraulic systems. They come in various types, including straight fittings, elbows, tees, and cross fittings. The assembly process involves cutting the hose to the required length, installing the fitting, and firmly crimping it to form a leak-free connection. Types include quick-connect couplings, threaded couplings, and flanged couplings. Quick-connect couplings are easy to install and remove, improving work efficiency, and are suitable for applications requiring frequent hose replacements; threaded couplings provide a more robust connection and are suitable for applications requiring high connection stability; flanged couplings are used in large hydraulic systems, offering convenient connection and the ability to withstand greater forces.
There are various connection methods for hydraulic hoses, including threaded connections, flanged connections, and compression fittings. Different connection methods have different requirements for the outer diameter of the hydraulic hose. For example, threaded connections require a thread on the outer diameter of the pipe, so the outer diameter of the pipe itself is larger than other connection methods. Compression fittings, on the other hand, do not require threads, so the outer diameter of the pipe can be relatively smaller.
Hydraulic hose fittings are important components for connecting hydraulic hoses to hydraulic equipment or other hoses. Hydraulic hose fittings come in various types to meet different application requirements, such as straight fittings, elbow fittings, and tee fittings. These fittings are designed to ensure the sealing of the hydraulic system and the stability of fluid transmission.
Straight fittings are the most common type of hydraulic hose fitting, used for straight connections between two hoses or devices. Elbow fittings are used to change the direction of fluid flow, accommodating complex layout requirements. Tee fittings allow for fluid distribution and control in three directions.
When selecting hydraulic hose fittings, attention must be paid to parameters such as the fitting material, connection method, working pressure, and temperature range to ensure compatibility with the hydraulic hoses used, thereby maintaining the stability and safety of the entire hydraulic system.

Cutting and Stripping: Use a dedicated cutting tool to cut the hose to the required length, ensuring a clean cut. Use the stripping machine to remove the outer adhesive from the hose end. The stripping length depends on the connector specifications, generally slightly longer than the connector's outer sleeve length.
Connecting the Connector: Insert the sleeve and connector onto the stripped end of the hose in sequence. The connector must be fully inserted, ensuring a tight fit against the hose's inner wall.
Crimping: Place the hose with the connector attached into the crimping machine mold, adjusting its position to align the connector with the mold's center. Start the crimping machine and press the connector's outer sleeve according to the set pressure and stroke, pressing it tightly against the hose. Observe pressure changes during the crimping process, ensuring the pressure is uniform and stable.
Inspection: After crimping, check that the connector and hose connection is secure, without any looseness or deformation. Inspect the appearance, ensuring there are no cracks, uneven indentations, or other problems. A simple pressure test can be performed to check for leaks; the device can only be used after passing the test.
