2. Product Introduction

Material

Performance

• Sealing and Wear Resistance: It boasts excellent sealing properties, high wear resistance, and elastic compensation ability. The dynamic pressure sealing life is 5 – 10 times longer compared to conventional rubber products.
• Pressure and Temperature Tolerance: It can withstand a maximum working pressure of up to 300MPa, and its temperature range spans from – 55 ºC to + 250 ºC.

Classification

• By Usage: It can be categorized into types such as high – temperature resistant, high – pressure resistant, and corrosion – resistant.
• By Structure: It includes UHSO rings, piston rod O – rings, etc.

3. Product Advantages

Multifunctionality

• Sealing Versatility: Suitable for both static and dynamic seals (including rotation and reciprocating motion). It is compatible with various media like oil, water, gas, and chemical substances.
• Extreme Condition Adaptability: By modifying the material formula, it can operate in extreme temperatures ranging from – 60 ºC to 220 ºC and high – pressure environments up to 1500kg/cm².

Economic Efficiency

• Standardized Design: Features a standardized design, which endows it with strong interchangeability, easy installation, and low maintenance costs.
• Cost – effective Material: Nitrile rubber (NBR) O – rings are cost – effective and have excellent resistance to mineral oil.

Durability

• Material – specific Resistance: Fluororubber (FKM) offers high – temperature and corrosion resistance, while silicone rubber (SIL) has good anti – aging properties and is suitable for the food and medical industries.
• Low Friction: It has low dynamic friction resistance, effectively preventing the “crawling” phenomenon during low – speed movement.

Structural Optimization

• Self – sealing: With a self – sealing design, no additional adjustment is required.
• Compatibility: It has standardized groove sizes, ensuring strong compatibility.

4. Product Application

Industrial Sector

• Hydraulic System: Used for piston sealing in hydraulic cylinders of construction machinery, capable of withstanding pressures up to 32MPa.
• Pneumatic Equipment: For example, cylinder seals, suitable for a temperature range of – 40 ºC to 120 ºC.

Transportation

• Automotive: Applied as oil seals in automotive engines and transmissions.
• Marine: Used for ship pipeline sealing.

Special Scenarios

• Harsh Environments: In high – temperature or corrosive environments, fluororubber O – rings are used in chemical equipment, while silicone rubber is used in food processing equipment.
• Precision Instruments: Used as dust – proof seals for aerospace equipment and electronic components.

Installation Method

• Radial Seal: The groove is designed inside the shaft or hole, making it suitable for static sealing.
• Axial Seal: Used for end – face sealing, where the pressure direction determines the matching of the inner/outer diameter of the O – ring.
