What is the difference between JIC and JIS？

American JIC thread is a commonly used thread standard, also known as SAE 37 degree thread or AN thread. It was developed by the Society of Mechanical Engineers (SAE) and is widely used in hydraulic system connections. Its characteristics are that the thread is a conical surface with an inclination angle of 37 degrees, and the sealing surface is a surface seal. The American made JIC thread has the advantages of convenient connection, high pressure, vibration resistance, and reliable sealing, and is therefore widely used in fields such as automobiles, aviation, ships, and petrochemicals.

Metric JIS thread is a Japanese Industrial Standard (JIS) thread standard and a national standard in Japan. It is a commonly used metric thread standard, widely used in industries such as mechanical engineering, automation control, aviation, shipbuilding, and chemical engineering. The characteristics of metric JIS threads are that the thread is a conical surface with a tilt angle of 60 degrees, and the sealing surface is a face seal or a side seal. Metric JIS threads have the advantages of convenient connection, simple structure, and good sealing performance, and are therefore widely used in various mechanical equipment and devices.

American JIC thread and Japanese JIS thread are commonly used connection connectorts in hydraulic systems. Although they adopt different unit systems and thread standards, and have differences in usage and application scope, they also have commonalities in certain aspects. This article will analyze their characteristics and application scenarios from similarities and differences.

Similarities

1. They are commonly used connection joints in hydraulic systems

American JIC thread and Japanese metric JIS thread are widely used as connection adapters in hydraulic systems. They can quickly and conveniently connect hydraulic systems when connecting pipelines, flanges, and other components.

2. Adopting a conical sealing structure

Both the American JIC thread and the Japanese JIS thread adopt a conical sealing structure to achieve sealing effect. The conical sealing structure can effectively prevent oil leakage in hydraulic systems, ensuring the sealing and stability of the system.

3. Has good durability and reliability

Both the American JIC thread and the Japanese JIS thread are made of high-quality materials and have characteristics such as corrosion resistance and wear resistance. Meanwhile, their structural design has undergone rigorous testing and verification, demonstrating high reliability and service life.

Differences

1. Different thread standards

The American JIC thread and the Japanese JIS thread use different thread standards. The American JIC thread adopts the British thread standard, while the Japanese metric JIS thread adopts the metric thread standard. This is also one of the important differences.

2. Different unit systems are used

The American JIC thread and the Japanese JIS thread use different unit systems. The American JIC thread uses the British system of units, while the Japanese JIS thread uses the metric system of units. This is also an important characteristic of the difference between the two.

3. Different applications for reversing and expanding connecting pipelines

The application of American JIC thread reversing and expanding connecting pipelines is more flexible and convenient, suitable for flexible pipeline connections and elastic light pipes; However, Japanese metric JIS threads require multiple adapter components for reversing and expanding connecting pipelines, which is relatively more difficult and costly to use than American JIC threads.

Summary

The above is an introduction to the characteristics and application scenarios of American JIC threads and Japanese metric JIS threads. Although there are differences in thread standards and units used between the two, they are both commonly used connection adapters in hydraulic systems, with high reliability and service life. Suitable connection adapters should be selected according to the actual situation and specific needs of the hydraulic system during use to ensure the stability and efficiency of the hydraulic system
