How do bite type tube fittings ensure sealing and prevent liquid or gas leakage?

Bite type tube fittings are widely used in pipeline systems due to their unique structural design and sealing principle, especially in the transportation of liquids and gases. Their sealing performance is crucial and directly related to the safety, reliability and working efficiency of the pipeline system. Bite type tube fittings ensure their sealing performance and prevent the leakage of liquids or gases through several key design elements.
The core sealing method of bite type tube fittings depends on its unique ferrule structure. The ferrule is usually made of metal material and has a certain elasticity. Its function is to form a good sealing interface by tightly clamping the surface of the pipe and the joint. When the pipe is inserted into the joint and tightened by the ferrule, the ferrule will exert a certain radial pressure on the pipe, so that the contact surface between the pipe and the joint forms a reliable seal. This close contact can effectively prevent liquid or gas from leaking at the joint and ensure the sealing effect.
The sealing performance of bite type tube fittings also depends on the sealing gasket inside the joint. Many bite type joints will set a sealing gasket between the ferrule and the pipe. This gasket is usually made of high temperature and corrosion resistant rubber or synthetic materials. Sealing gaskets can provide an additional sealing layer between two contact surfaces, effectively fill tiny gaps, and form a barrier to liquids or gases in the pipeline. Even under high pressure, high temperature or vibration, gaskets can maintain a stable sealing effect and reduce the risk of leakage.
In addition to ferrules and sealing gaskets, the sealing effect of ferrule-type pipe fittings is also closely related to the selection of their materials. The materials of ferrule-type fittings usually have high strength and corrosion resistance. Especially in some special applications, such as chemical transportation or high-temperature fluid transmission, the selection of highly corrosion-resistant materials such as stainless steel and copper alloy can effectively extend the service life of the fittings and prevent leakage caused by material corrosion. In harsh environments, the materials of ferrule-type pipe fittings can withstand external pressure and medium erosion to ensure long-term stable operation.
During the installation process, the sealing of ferrule-type pipe fittings can also be further guaranteed. The installation process of the ferrule is usually very simple, but it should be noted that the ferrule must be tightly matched with the pipe during installation. Improper installation or over-tightening may affect the sealing effect and even cause damage to the fitting. Therefore, the correct installation method and appropriate torque control are the key to ensuring sealing performance. Most ferrule-type fittings are designed with special ferrule tools to help users complete installation easily and accurately, avoiding sealing problems caused by human factors.
The durability of ferrule-type pipe fittings is also an important factor in ensuring their sealing. With long-term use, the pipeline system may be subject to changes in the external environment, such as temperature fluctuations, pressure fluctuations, vibrations, etc. These factors may cause aging or deformation of the joints, thereby affecting the sealing performance. For this reason, regular inspection and maintenance are very necessary. During long-term use, if the ferrule or sealing gasket is found to be worn or aged, it should be replaced in time to prevent leakage problems caused by aging.
