About Metric O-Rings Kits
Metric O-rings kits are an important part of the hydraulic system. Their function is to ensure that the system’s hydraulic fluid does not leak under high-pressure and high-speed working environments, thereby maintaining efficient and stable operation of the system.

Advantages
1. Good sealing effect: The O-ring kit has good sealing performance, which can effectively prevent the leakage of hydraulic oil, lubricating oil and other fluids, and ensure the normal operation of the hydraulic system.
2. Wide range of applications: Metric O-ring kits are suitable for a variety of sealing forms, such as static seals and dynamic seals, and can be used for a variety of motion modes, such as rotational motion, axial reciprocating motion and combined motion, etc. In addition, it can be applied to a variety of sealing media, such as air, water, oil, etc.
3. Low cost: The cost of the O-ring kit is relatively low because it adopts standardized size and groove design and can be purchased and replaced easily.
4. High reliability: Since the material of the O-ring kit is usually oil-resistant and wear-resistant rubber material, it has a long service life and high reliability.
5. Strong adaptability: Metric O-ring kits are suitable for a variety of industries and fields, such as machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, etc., which shows that they have strong adaptability.
6. Complete specifications: The sizes of metric O-ring kits have been standardized, and the conventional sizes are complete. There is no need to re-make private molds, and they are highly interchangeable.
Application Scenarios
Metric O-ring kits are widely used in various industries and fields, including but not limited to the following application scenarios:
1. Hydraulic system: Metric O-ring kits are used in hydraulic systems, such as machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, etc. In these systems, O-ring kits are used to seal the hydraulic fluid to ensure efficient and stable operation of the system.
2. Pneumatic system: In pneumatic systems, metric O-ring kits are used to seal the flow of gas or air and prevent it from leaking. These systems often rely on fluid transfer under pressure, so the sealing action of the O-ring kit is critical to maintaining system efficiency.
3. Automotive industry: In the automotive industry, O-ring kits are widely used for sealing various components such as engine blocks, transmission systems, fuel injectors, and braking systems. They can also be used to seal air conditioning and cooling systems to prevent refrigerant leaks.
4. Aerospace industry: In the aerospace industry, O-ring kits are used to seal fuel tanks, hydraulic systems and other key components. They can also be used to build spacecraft, satellites and other space exploration equipment.
5. Medical industry: In the medical industry, O-ring kits are used to seal medical equipment and devices, syringes and other medical supplies. They can also be used in prosthetic devices and surgical implants.
6. Food and Beverage Industry: In the food and beverage industry, O-ring kits are used to seal containers, pipes and other equipment used in food and beverage processing, packaging and transportation. These devices are often required to comply with food safety standards, so the use of O-ring kits can ensure food safety.
7. Chemical Industry: In the chemical industry, O-ring kits are used to seal pumps, valves, pipes and other equipment used in chemical manufacturing and processing. Since these devices are often exposed to a variety of chemicals, O-ring kits need to be chemically resistant.
8. Marine Industry: In the marine industry, metric O-ring kits are used to seal various components such as engine blocks, pumps, valves and other marine equipment. They can also be used in underwater exploration equipment.
Classification
There are two main types of metric O-ring kits: static O-rings and dynamic O-rings.
1. Static O-rings are mainly used for fixed seals, such as sealing box covers, flanges, etc., and their function is to prevent liquid or gas from leaking in a static state.
2. Dynamic O-rings are used for seals with relative motion, such as hydraulic cylinders, pneumatic components, etc., which need to prevent leakage of internal media and the intrusion of external impurities, dust, etc.
