● High-strength metal: brass, stainless steel and other high-strength metals are commonly used to ensure no deformation and no leakage under high pressure.
● Excellent sealing materials: sealing rings or O-rings are made of oil-resistant and wear-resistant synthetic rubber or polytetrafluoroethylene to ensure high sealing.
● Corrosion resistance: corrosion-resistant alloys or surface treatments such as galvanizing and chrome plating are selected to adapt to harsh working environments.
● Good thermal conductivity: the material has good thermal conductivity, which helps to dissipate heat and avoid failures caused by overheating in the hydraulic system.
● Lightweight and durable: while ensuring strength, the material selection also focuses on lightweight, which is easy to install and maintain, while ensuring durability under long-term use.

● Connection function: Externally threaded hydraulic connectors are mainly used to connect various components in the hydraulic system, such as hydraulic cylinders, hydraulic pumps, hydraulic valves, etc., to ensure that the hydraulic system can form a complete and closed working circuit. Through its external thread design, it can be easily connected to other components with internal threads to achieve fast and stable assembly.
● Transmission function: In the hydraulic system, the externally threaded hydraulic connector is responsible for transmitting hydraulic oil. When the hydraulic system is working, the hydraulic oil will flow between the various components to transfer pressure and energy. Externally threaded hydraulic connectors can ensure the smooth transmission of hydraulic oil and avoid system failure caused by loose connection or leakage.
● Sealing function: Externally threaded hydraulic connectors have excellent sealing performance and can effectively prevent hydraulic oil leakage. Its sealing structure usually uses sealing elements such as O-rings and metal sealing rings. These sealing elements can maintain a tight fit under high pressure environments to ensure the sealing of the hydraulic system.
● Pressure-bearing function: Externally threaded hydraulic connectors can withstand the high pressure generated when the hydraulic system is working. Its material and structural design have been strictly calculated and tested to ensure stable performance and safety under high pressure environments.
● Adapt to a variety of media: The External Thread Hydraulic Connector is suitable for a variety of media, such as mineral oil, synthetic oil, emulsion, etc. This enables it to be widely used in various hydraulic systems to meet the needs of different industries and fields.
