中文简体1. Hydraulic system
EMA3 male point fitting are widely used in hydraulic systems, especially for equipment such as engineering machinery, injection molding machines and hydraulic power units. Its design can reliably connect pressure-resistant hoses, hydraulic cylinders, valve blocks or pump stations to ensure the stability of high-pressure fluid transmission. The self-sealing valve function of the connector can effectively prevent hydraulic oil leakage during disassembly, which not only reduces oil waste but also avoids environmental pollution. At the same time, its external thread ED sealing structure complies with the ISO 9974-1 standard and can withstand high pressures above 35MPa, ensuring the sealing reliability of the system under harsh working conditions. In addition, EMA3 connectors provide metric and imperial thread options, which can adapt to equipment standards in different countries and regions, making it widely applicable worldwide.
2. Pneumatic system
In pneumatic systems, EMA3 male point fitting are often used in scenarios such as automated production lines, pneumatic tools and compressed air pipelines. It can work seamlessly with quick connectors with ejectors and is suitable for the connection of components such as cylinders and gas tanks. The self-sealing valve design of the connector can automatically close the pipeline when disconnected, preventing the instantaneous release of compressed air, thereby avoiding potential safety hazards. In addition, its operating temperature range can meet the needs of most pneumatic systems, ensuring stable sealing performance in low or high temperature environments.
3. Cooling/lubrication system
EMA3 external thread connector performs well in cooling and lubrication systems, especially for applications such as machine tool coolant pipelines, engine lubrication systems and central cooling systems. It can be reliably connected with corrosion-resistant hoses, filters or oil cooler interfaces to ensure smooth fluid transmission. The connector is usually made of oil-resistant materials, which can effectively resist the corrosion of coolants or lubricants and extend its service life. Its excellent sealing performance can reduce the risk of fluid leakage and avoid pollution of the working environment or damage to equipment caused by leakage.
4. Chemical and fluid transportation
In the chemical, pharmaceutical and food processing industries, EMA3 external thread connectors are widely used in chemical delivery pipelines, pharmaceutical equipment and food-grade fluid handling systems. It can be used with food-grade hoses (such as PTFE) or sanitary connectors with ejectors to meet strict hygiene requirements. The connector complies with ISO 1179-1 standard, and its sealing material can withstand corrosion by acids, alkalis and organic solvents, ensuring long-term reliability in corrosive media. In addition, its quick-connect design facilitates equipment cleaning and maintenance, and is particularly suitable for sanitary applications that require frequent disassembly.
5. Energy and Oil and Gas Industry
In the energy and oil and gas fields, EMA3 external thread connectors are commonly used in fuel delivery pipelines, natural gas equipment and offshore platform hydraulic control systems. It can be reliably connected with high-pressure hoses and explosion-proof connectors to meet the needs of use under extreme working conditions. The pressure-resistant design of the connector enables it to withstand pressures of up to 10,000 psi and maintain stable performance under pulse conditions. In addition, in harsh environments such as high salt spray at sea, the connector can be made of rust-proof materials (such as 316 stainless steel) to ensure long-term corrosion resistance, reduce maintenance frequency and improve system reliability.
6. Transportation
EMA3 external thread connectors play an important role in the transportation industry, especially in commercial vehicle braking systems, railway vehicle pneumatic brakes and ship hydraulic pipelines. It can reliably connect with key components such as brake hoses and air dryer interfaces to ensure safe operation of the system. The connector adopts a seismic design to adapt to the high-frequency vibration environment during vehicle operation and avoid leakage problems caused by looseness. At the same time, its sealing performance can effectively prevent the leakage of brake fluid or compressed air to ensure the reliability of the braking system. In addition, the connector provides imperial thread options to adapt to North American vehicle standards and meet global application needs.
