Hydraulic Sealing Products

Sealing plays a very important role in hydraulic systems when conveying fluids under high pressure. The sealing products used in these systems ensure the efficient operation of the system, especially preventing the uncontrolled leakage of fluids.

Sealing elements are of critical importance to ensure the long life of hydraulic equipment, pipelines, and machinery.

The sealing products used in hydraulic systems are produced with various engineering solutions and customized according to the needs of the system. These products must be resistant to various factors such as pressure, temperature, chemical interaction, and mechanical stress.

What Are Hydraulic Sealing Products?

Hydraulic sealing products generally consist of the following elements:

1. O-Ring
   O-Ring is one of the most common elements that provide sealing. These parts, usually round in shape, are used in the connections of pipes, valves, pumps, and other hydraulic components. O-Rings are essential for ensuring fluid tightness in both low and high-pressure systems.

2. Y-Ring
   Y-Rings are used to provide tight sealing under high pressure, especially in hydraulic systems. These products are more durable than O-Rings and are preferred, especially for dynamic sealing applications. Y-Rings are used in more complex and special systems.

3. D-Ring
   D-Ring ensures that two different surfaces fit tightly together to prevent the leakage of liquids or gases. These types of sealing products are used especially under conditions of higher wear and high temperatures.

4. Lip Seal
   Lip seals, also known as zipper sealing elements, are used to provide fluid tightness, especially in moving components. These elements are usually cylindrical in structure and provide a tight seal around the shaft.

5. Sealing Rings
   Seals are generally used in large-scale hydraulic systems. These seals provide sealing by wrapping around pipes or pipe connections. Seals are usually made of elastomeric materials and are suitable for both dynamic and static applications.

6. Shaft Seals
   Shaft seals are elements used to provide sealing for shafts, especially. Seal types are designed to withstand the rotational movement of the shaft and provide sealing. These products perform effectively under high pressure and temperature conditions.

7. Cylinder Sealing Elements
   Sealing elements between the pistons and the body in hydraulic cylinders prevent the escape of fluids. These elements are usually made of elastomers and provide sealing even under high-pressure conditions.

8. High-Pressure O-Rings and Butterfly Seals
   These sealing elements are used especially in high-pressure systems. They provide effective results in both static and dynamic sealing applications. Butterfly seals are used especially where rotary motion is required.

9. PTFE (Polytetrafluoroethylene) Seals and Sealing Elements
   PTFE is a material with high chemical resistance and is generally preferred in hydraulic systems working with liquids, gases, and chemicals. PTFE provides excellent sealing, especially under high-temperature and pressure conditions.

10. Silicone Sealing Elements
    Silicone is a material with high elasticity and temperature resistance. Thanks to these properties, it is preferred to provide sealing in hydraulic systems used in food, medical, and chemical industries.

Advantages of Hydraulic Seals

1. High Sealing Performance
   Hydraulic sealing elements offer high performance for providing sealing. These elements are designed to be resistant to pressure, temperature, and other environmental conditions, ensuring sealing.

2. Long Service Life
   These sealing products are made of durable materials and provide long-term efficient operation when used correctly. They reduce the failure rate of hydraulic systems and lower maintenance costs.

3. Chemical Resistance
   Sealing elements used in hydraulic systems are resistant to chemical substances. These sealing products provide safe and efficient use, especially in systems working with acidic, basic, and other corrosive liquids.

4. Low Friction and Wear
   Most sealing elements are designed to minimize friction. This ensures the efficient operation of the system and also prevents wear and tear.

5. High Temperature Resistance
   High temperature conditions are common in hydraulic systems. Sealing elements are manufactured to withstand these temperatures and ensure the safe operation of the system.

Material Selection in Hydraulic Seals

The selection of materials for sealing elements used in hydraulic systems varies according to the operating conditions of the system. Commonly used materials include:

• Nitrile Rubber (NBR): Nitrile rubber, commonly used in O-Rings and sealing products, is resistant to oil, gasoline, and other petroleum-based liquids. It generally offers heat-resistant and cost-effective sealing solutions.

• Fluoroelastomer (FKM): Used in applications requiring high-temperature resistance and chemical resistance. It is generally preferred in high-performance hydraulic systems.

• Acetal (POM): Acetal provides low friction coefficient and high wear resistance. It is ideal for hydraulic systems operating at high speeds.

• Silicone: Silicone, providing high-temperature tolerance and excellent elasticity, is used especially in medical, food processing, and automotive applications.

• Polytetrafluoroethylene (PTFE): PTFE has very high chemical resistance and excellent heat resistance. It is commonly preferred in chemical and industrial systems.

Application Areas of Hydraulic Seals

Hydraulic sealing elements are widely used in many different industries. Some important application areas are:

• Construction and Heavy Machinery Equipment: Sealing products used in high-pressure hydraulic systems ensure efficient operation of large machines such as construction machinery, excavators, and loaders.

• Automotive Sector: Sealing elements are used in vehicles, especially in steering systems, brake systems, and engines, to provide safe and efficient operation.

• Oil and Gas Industry: Hydraulic sealing elements are used in oil and gas pipelines, drilling equipment, and other industrial applications.

• Machine Industry and Automation: Sealing products play a critical role in high-pressure and precision systems such as hydraulic presses, injection molding machines, and robotic systems.
