Product Introduction
Rubber O-ring is a sealing element with a circular cross-section, made of polyurethane (TPU, CPU) or rubber (such as nitrile rubber, fluororubber, etc.). Its core function is to prevent liquid or gas leakage, and it is widely used in static and dynamic sealing scenarios of hydraulic, pneumatic systems and various mechanical equipment.
1.Material: Common materials include nitrile rubber (NBR), fluororubber (FKM), silicone rubber (SIL), ethylene propylene diene monomer (EPDM), etc. Different materials are suitable for different temperature, medium, and pressure conditions.
2.Performance: It has excellent sealing, wear resistance, and elastic compensation ability. The dynamic pressure sealing life is 5-10 times longer than conventional rubber products, and the maximum working pressure can reach 300MPa. The temperature range covers -55 ºC to+250 ºC.
3.Classification: According to usage, it can be divided into high-temperature resistant,high-pressure resistant, corrosion-resistant, etc; Divided by structure into UHSO rings, piston rod O-rings, etc.

Product advantages
1.Multifunctionality:
Suitable for static and dynamic seals (rotation, reciprocating motion), compatible with oil, water, gas, chemical media, etc.
By adjusting the material formula, it can adapt to extreme temperatures (-60 ºC~220 ºC) and high-pressure (1500kg/cm ²) environments.
2. Economically efficient:
Standardized design, strong interchangeability, easy installation, and low maintenance cost.
Nitrile rubber (NBR) O-rings have low cost and excellent resistance to mineral oil.
3. Durability:
Fluororubber (FKM) is resistant to high temperatures and corrosion; Silicone rubber (SIL) is resistant to aging and suitable for the food and medical industry.
The dynamic friction resistance is small, avoiding the "crawling" phenomenon during low-speed movement.
4. Structural optimization:
Self sealing design, no additional adjustment required; Standardized groove size and strong compatibility.

Product application
1. Industrial sector:
Hydraulic system: used for piston sealing of hydraulic cylinders in construction machinery, with a pressure resistance of up to 32MPa.
Pneumatic equipment: such as cylinder seals, suitable for temperature range of -40 ºC~120 ºC.
2. Transportation:
Automotive engine and transmission oil seals; Ship pipeline sealing.
3. Special scenarios:
High temperature/corrosive environment: Fluororubber O-rings are used in chemical equipment; Silicone rubber is used in food processing equipment.
Precision instruments: such as dust-proof seals for aerospace equipment and electronic components.
4. Installation method:
Radial seal: The groove design is located inside the shaft or hole, suitable for static sealing.
Axial seal: used for end face sealing, the pressure direction determines the matching of the inner/outer diameter of the O-ring.

Main Products

Rubber products are used in industries such as vibrating screens, vibrating feeders, petroleum machinery, special machinery, mining equipment, etc.
