There are many ways to connect hydraulic hoses. Depending on the application requirements and system design, different types of connectors can be selected to achieve safe and reliable connections. The following are some common ways to connect hydraulic hoses
O-ring end seal hose connector
This connector uses an O-ring as a sealing element, and the O-ring is compressed by screwing the nut and the connector body to achieve a sealing effect. During installation, special attention should be paid to checking the condition of the O-ring to ensure that it is intact.
24° cone seal end hose connector
This type of connector uses a 24-degree cone contact to form a seal, and is usually used with an O-ring to enhance the sealing performance. The pressure between the cones is large, which can theoretically provide a better sealing effect.
Flange end hose connector
The flange end connector presses the hose flange head tightly against the oil port through the flange pressure plate, and uses the preload force generated by the high-strength bolt to ensure sealing. This connector is suitable for high-pressure and large-diameter applications.
Stud end hose connector
The root of the connector thread has an O-ring. When the connector is connected to the oil port through the thread, the O-ring will fit with the end face of the oil port to seal. This is a relatively simple connection method, suitable for situations where frequent disassembly is not required.
37° flared end hose connector
In this connection, the end of the steel pipe is expanded into a 37-degree cone, and then tightly fits with the outer cone of the hose connector, and the seal is achieved by tightening the nut. This connection method is widely used in the connection between hard pipes and hoses.
Ferrule type connector
The ferrule type connector consists of a connector body, a ferrule and a nut. The outer side of the front end of the ferrule fits the cone surface of the connector body, and the inner edge bites into the seamless steel pipe evenly to form an effective seal. It is suitable for small and medium diameter pipes, easy to install and low cost.
JIC 37 degree connector
The JIC 37 degree connector is another common conical sealing connector. Its sealing principle is similar to that of the 37° flared end, but it is usually used in the American standard system. This connector also requires the use of a bushing and is formed at the end of the steel pipe by the flaring equipment before connection.
