There are many different types of hose fittings, here are three common types:

External thread connector:

A male nipple is a common pipe connector that has threads on the inside that allow it to be connected and disconnected from a hose. When installing this kind of joint, you only need to use a little force to insert the quick connector into the pipe opening that needs to be blocked to form a seal. The operation is simple and convenient, saving time and effort, and reducing the operator’s labor intensity. At the same time, it is exquisite and compact, easy to carry, suitable for smaller spaces, and eliminates the inconvenience of operation such as wrenches. The sealing connection is fast, one second connection, instant sealing, saving time, making the work more efficient and making batch operations easier. Moreover, its sealing performance is good, the claws are tight, the sealing ring is sealed, the sealing performance is stable, and the test results are more accurate. In addition, it also has the characteristics of pressure resistance, high temperature resistance, low temperature resistance, wear resistance and durability.

Internal thread connector:

An internal threaded joint is a hollow rubber product usually used to connect metal pipes. Its structure usually includes inner and outer rubber layers, ply layers and wire rings. After these parts are combined and vulcanized, they can be combined with metal flanges or loose sleeves of parallel joints. According to the structure, the internal thread joint can be divided into three types: single sphere, double sphere and threaded type. According to the sealing surface, it can be divided into two types: smooth type and concave and convex type. The main features of this kind of joint include high elasticity, medium hardness, medium resistance and good air tightness, so it is widely used in pipeline shock and noise reduction equipment. During installation, you need to first insert the pipe with internal threads into the bolt hole on the end face, then insert the other end with external threads into the annular gap at the socket end and press it firmly. This can control the system error within the allowable range, greatly reduce the pressure requirements on pumps and valves, and improve the system operating characteristics. At the same time, due to their good flexibility, internal thread joints can also reduce structural transmission noise and have strong vibration absorption capabilities, so they are considered to be a pipe connection method with good performance.

bite type tube fitting:

Bite type tube fitting is a common pipe connection method. Its main components include the joint body, ferrules and nuts. During assembly, first put the ferrule and nut on the steel pipe, then insert the set steel pipe into the joint body, and finally tighten the nut so that the outside of the front end of the ferrule fits the conical surface of the joint body, and the inner blade bites evenly into seamless steel pipe to form an effective seal. This kind of joint has the advantages of convenient connection, good sealing performance, excellent vibration resistance, and long service life. Therefore, it has been widely used in industry, construction, water supply and drainage and other fields. At the same time, bite type tube fitting also has the advantages of easy maintenance and easy replacement, so it is considered an ideal pipe connection method. However, bite type tube fittings also have some disadvantages, such as being easily damaged under high temperatures or pressures, so they require regular inspection and maintenance. In addition, the structure of bite type tube fitting is relatively complex, so a certain technical level is required to install and maintain it correctly. During installation, it is necessary to ensure the verticality of the steel pipe and the joint body to prevent the ferrule and nut from falling off or being damaged. At the same time, when tightening the nut, you need to apply even force to avoid problems such as poor sealing. In short, bite type tube fitting is a relatively common pipe connection method. It has the advantages of convenient connection, good sealing performance, excellent vibration resistance, and long service life. Therefore, it has been widely used in industry, construction, water supply and drainage and other fields. However, during use, you also need to pay attention to protection and maintenance issues under high temperature or high pressure, as well as technical requirements during installation.

Insert connector:

Insert joints are a common way to connect pipes, and their main feature is that they can connect and disconnect pipes quickly and easily. Insert joints usually consist of two parts, one is the insertion tube and the other is the joint body. The insertion tube is usually made of steel or copper tube and has a threaded surface or a smooth surface that can fit closely with the joint body. When in use, the insertion tube is inserted into the joint body, and the insertion tube and the joint body are tightly connected by tightening nuts or buckles to achieve sealing and connection of the pipes. Insert joints have the advantages of convenient connection, good sealing performance, excellent vibration resistance, and long service life. Therefore, they have been widely used in industry, construction, water supply and drainage and other fields. However, male connectors also have some disadvantages, such as being susceptible to damage under high temperatures or pressures, so they require regular inspection and maintenance. In addition, due to the complex structure of the plug-in connector, a certain technical level is required for correct installation and maintenance. During installation, it is necessary to ensure the verticality of the insertion pipe and the joint body to avoid problems such as poor connection. In short, the plug-in joint is a relatively common pipe connection method. It has the advantages of convenient connection, good sealing performance, excellent vibration resistance, and long service life. Therefore, it has been widely used in industry, construction, water supply and drainage and other fields. However, during use, you also need to pay attention to protection and maintenance issues under high temperature or high pressure, as well as technical requirements during installation.
