How many types of hydraulic hose connectors are there? What should I pay attention to?

Leave a message

Hydraulic hose connectors come in a wide variety of sizes, with common sizes ranging from 4 to 42. The following points should be noted when using them:

I. Hydraulic Hose Connector Models

Hydraulic hose connectors come in a variety of sizes, primarily based on the hose's inner diameter. Common sizes include 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 32, 34, 40, and 42. These connectors connect to the hose using either metric fine threads or imperial pipe threads, and are available in both sealed and non-sealed thread types. Furthermore, hydraulic hose connectors come in a variety of styles, including straight connectors, elbows (generally 90° connectors), and 45° connectors, depending on the connection requirements.

II. Usage Precautions

Compatibility: When selecting a connector, ensure it matches the hose's inner diameter, operating pressure, and operating environment to ensure a stable and secure connection.

Thread Type: Select the appropriate connection method based on the thread type (metric or imperial) of the hose and fitting to avoid leaks caused by thread mismatch.

Sealing Performance: For applications requiring sealing, use sealed threaded fittings and ensure that the threads are fully tightened during installation to achieve a good seal.

Material Selection: Select an appropriate fitting material, such as stainless steel or copper alloy, based on the working environment and usage requirements to improve corrosion resistance and service life.

Installation Specifications: When installing fittings, follow the product manual and operating procedures to avoid damage or leaks caused by overtightening or improper installation.
