Introduction
Straight thread O-rings are a seal used to connect pipes, valves, pumps, and other equipment. It is usually used for metric straight thread connections.
This design enables the threaded O-ring to have both connection and sealing functions, greatly improving the reliability and efficiency of the system.
Advantages
1. Excellent sealing performance: O-rings have good elasticity and can maintain effective sealing under various working conditions and prevent fluid leakage.
2. Simple and compact structure: The design of the straight thread O-rings makes it compact in structure, easy to install, takes up little space, and is suitable for various equipment and systems.
3. Strong wear resistance: The threaded O-ring is made of high-quality materials, has good wear resistance and can be used for a long time in harsh environments.
4. Self-sealing effect: O-rings are self-sealing, and only one seal can achieve the ideal sealing effect, reducing sealing costs.
5. Strong adaptability: Threaded O-rings are suitable for various movement modes and different sealing media, such as rotational movement, axial reciprocating movement, oil, water, gas, and other media.
6. Strong interchangeability: The size and groove of threaded O-rings have been standardized, making them highly interchangeable and easy to repair and replace.

Classification
1. Metric straight thread O-rings: This type of O-ring is usually used to connect pipes, valves, pumps, and other equipment to achieve sealing and connection functions. Its threads comply with metric standards and are highly versatile and interchangeable.
2. American thread O-ring: This type of O-ring is mainly used in the United States and some other countries and its threads comply with American standards. It may vary in size and specification compared to metric straight-thread O-rings.
3. Special-purpose threaded O-rings: This type of O-ring is designed for a specific application or equipment, and its size, specifications, and materials may differ from other types of O-rings. Threaded O-rings are usually used in situations that have special requirements for sealing performance, such as high pressure, high temperature, or highly corrosive environments.
