Hydraulic Tube Fittings (DIN2353/ISO8434) are commonly used in fluid power systems for connecting tubes or hoses. These fittings provide a reliable and leak-free connection by using a biting action to grip the tube.
Design: Hydraulic tube fittings typically consist of a body, a nut, a ferrule (also known as a progressive ring/cutting ring/sleeve or collar), and sometimes an elastomeric seal. The body contains a tapered surface or a series of sharp serrations that grip the tube when the nut is tightened.
Assembly: To assemble a bite-type fitting, the nut and ferrule are slid onto the tube, and then the tube is inserted into the body of the fitting. As the nut is tightened onto the body, it compresses the ferrule around the tube, causing it to bite into the tube surface and create a secure seal.
Materials: These fittings are often made from materials such as steel (MS/CS), stainless steel (SS304/SS316), or brass, depending on the application requirements. The choice of material depends on factors such as the operating pressure, temperature, and compatibility with the fluid being conveyed.
Size & Configurations: Hydraulic tube fittings are available in a range of sizes (For Ex: 06mm to 42mm) and configurations to accommodate different tube diameters and connection requirements. They may also be available with different end connections, such as NPT, BSPP, or SAE threads, to suit specific system designs.
Applications: These fittings are commonly used in various industries, including hydraulic systems in construction equipment, agricultural machinery, industrial machinery, and automotive applications.
Overall, Hydraulic Tube Fittings are a popular choice for hydraulic systems due to their reliability, durability, and ease of installation
