Rubber O-Ring with Protrusions / Rubber O-Ring with Indentations

Characteristics
Unique Surface Structure: The protrusions on the surface can enhance the contact pressure with the sealing surface, improving the sealing effect. The indentations can store lubricating substances, achieving auxiliary lubrication and buffering functions. This special structure endows it with functions beyond those of ordinary O-rings.
Good Elasticity: It has the high elasticity of rubber and can quickly return to its original shape after being squeezed and deformed. This ensures that it can closely fit the sealing surface under various working conditions, maintaining stable sealing performance, especially in sealing scenarios with vibration and easy displacement. It can maintain good sealing in a dynamic environment.
Wear Resistance: By optimizing the shape, distribution, and density of the protrusions and indentations, it can effectively disperse the frictional force during relative movement, reducing local wear and extending the service life of the product. It has significant advantages in frequently moving parts of equipment such as engines and hydraulic systems.
Chemical Stability: Depending on the selected rubber material (such as ethylene propylene diene monomer rubber, silicone rubber, etc.), it has a certain tolerance to common chemical substances and can work stably in a variety of chemical environments, meeting the needs of different industrial scenarios.
Anti-fatigue Property: The special surface structure can relieve stress concentration. During frequent compression and extension cycles, it reduces the fatigue damage of the rubber material and improves its anti-fatigue ability, ensuring continuous performance under long-term vibration and displacement working conditions.

Functions

01

Enhanced Sealing Performance: The protrusions closely contact the sealing surface, effectively preventing the leakage of liquids, gases, and other media. It performs excellently in harsh sealing scenarios such as high pressure and high vacuum. In sealing parts of engines, hydraulic systems, and pipeline connections with vibration and easy displacement, it can effectively prevent media leakage due to its unique structure.

Auxiliary Lubrication: The lubricating medium stored in the indentations provides lubrication when the O-ring moves relative to the sealing surface, reducing the coefficient of friction, minimizing wear, and ensuring smooth movement, which is crucial for the piston movement in hydraulic systems.
02

Buffering and Vibration Damping: The structure of protrusions and indentations can absorb and buffer vibrations and impact forces, reducing the impact of mechanical vibrations on the sealing system and ensuring the stable operation of the equipment. It plays a key role in vibrating equipment such as engines.

Prevention of Adhesion: The convex-concave structure on the surface disrupts the close fit with the sealing surface, reducing the adhesive force and preventing adhesion when stationary for a long time or under external force. This facilitates the disassembly and maintenance of equipment in parts such as engines and pipeline connections.

Advantages

01

Multifunctional Integration: It integrates multiple functions such as sealing, lubrication, and buffering, meeting the requirements of complex working conditions, reducing the use of auxiliary components, and lowering the complexity and cost of the system. It has obvious advantages in sealing scenarios with vibration and easy displacement.

Strong Adaptability: According to different usage requirements and working conditions, the parameters of the protrusions and indentations (such as shape, size, distribution, etc.) can be flexibly adjusted to optimize its performance and adapt to diverse working environments and media. It can cope with the high temperature and high pressure of engines as well as the complex working conditions of pipeline connections.
02

Improved Equipment Reliability: By strengthening sealing, reducing wear, and fatigue damage, it improves the reliability and stability of the equipment, reduces the failure rate, and shortens the downtime and maintenance cost, which is of great significance for core equipment such as engines and hydraulic systems.

Wide Range of Material Selection: Based on different rubber materials, it can adapt to different temperature, chemical medium, and other environmental conditions, with a wide application range, and can meet the needs of various sealing scenarios with vibration and easy displacement.

Application Scenarios

01

Hydraulic Systems: Used for sealing parts such as the pistons and cylinders, and pipeline connections of hydraulic cylinders and hydraulic pumps. These parts often have vibration and are prone to displacement. The rubber O-ring with protrusions and indentations can prevent hydraulic oil leakage, ensure the pressure stability of the hydraulic system and the energy transfer efficiency. The auxiliary lubrication function can also reduce the friction between components and improve the working efficiency of the system.

Pneumatic Systems: Suitable for the sealing of pneumatic components such as cylinders and air valves, ensuring the sealing of compressed air and achieving precise motion control. Its buffering and vibration damping function can reduce the vibration and noise during the operation of the pneumatic system, and it works well in some pneumatic equipment with slight vibration.
02

Automotive Industry: In parts such as the piston ring grooves and valve stem seals of automotive engines, the engine vibrates strongly during operation and the components are prone to displacement. The rubber O-ring with protrusions and indentations can prevent engine oil leakage and the intrusion of combustion gas into the crankcase, ensuring the normal operation of the engine. It is also applied in the braking and transmission systems, improving the safety and reliability of the vehicle.

Aerospace Field: The fuel systems, hydraulic systems, and various sealing parts of aircraft have extremely high requirements for sealing and are often in complex working conditions such as vibration and displacement. With its excellent sealing and anti-fatigue performance, it can ensure flight safety and the reliable operation of equipment under extreme conditions, such as the high-temperature and high-pressure sealing parts of engines and the frequently moving parts of landing gears.
03

Mechanical Manufacturing: In the sealing of rotating or reciprocating moving parts of mechanical equipment such as pumps, compressors, and reducers, these parts vibrate and displace during operation. The rubber O-ring with protrusions and indentations can adapt to different working conditions, reduce the risk of leakage, improve the stability and reliability of the equipment. Its good wear resistance and anti-fatigue performance can extend the service life of the equipment.

Water Industry: In water treatment equipment (such as filters, water pumps, valves, etc.), it is used to prevent water leakage and ensure the normal operation of the equipment. Due to the different corrosiveness and impurity content of water, selecting the appropriate rubber O-ring with protrusions and indentations can effectively resist the erosion of water and chemical substances in the water, ensuring long-term stable sealing performance. Even when the water pump vibrates during operation, it can work normally.
04
Sanitary Ware Industry: Widely used in sanitary ware products such as faucets, showerheads, and toilets, it plays a role in sealing and waterproofing. Its unique structure can not only effectively prevent water leakage but also reduce the friction between components, making the operation smoother, extending the service life of sanitary ware products, and improving the user experience. It can also maintain good sealing performance in some sanitary ware equipment that vibrates due to water flow impact.

Application Environment

01
Temperature Environment: Depending on the rubber material, the applicable temperature range varies. Ethylene propylene diene monomer rubber materials can generally be used at temperatures ranging from -50°C to 150°C; silicone rubber materials can work normally at temperatures ranging from -60°C to 250°C. Within the corresponding temperature range, it can maintain good elasticity and sealing performance, and can adapt to both the high-temperature environment of engines and the possible low-temperature environment in the water industry.
