Oil seals are essential components used to prevent the leakage of fluids and contaminants in various industrial applications. Two commonly used oil seals are TC oil seals and TG4 oil seals. While they share the same objective of providing effective sealing, they differ in design, materials, and application scenarios. This article aims to provide a detailed analysis of their characteristics and applications.

TC Oil Seal Features and Applications: TC oil seals feature a double-lip design, with one lip acting as an elastic element to ensure stable sealing performance under different operating conditions. Due to their compact structure, TC oil seals are well-suited for applications in limited spaces. They are widely used in the automotive industry for engine, transmission, and bearing components, as well as in various industrial equipment. TC oil seals effectively prevent the ingress of liquids and contaminants, providing reliable sealing performance.
TG4 Oil Seal Features and Applications: In comparison, TG4 oil seals also feature a double-lip design but are made of polyurethane, offering higher wear resistance and chemical resistance. As a result, TG4 oil seals find broader applications in harsh environments such as the metallurgical industry, mining equipment, and hydraulic systems. TG4 oil seals improve equipment efficiency and lifespan by reducing leakage and friction.
Differences and Comparisons: TC oil seals and TG4 oil seals exhibit distinct differences in design and materials, thus serving different purposes in various application scenarios. TC oil seals are suitable for use in compact spaces, while TG4 oil seals are more suitable for demanding environments. When choosing between the two, factors such as operating conditions, material requirements, and desired sealing performance should be considered. Effective communication and collaboration with manufacturers and engineers are recommended to ensure the selection of the best sealing solution.
When selecting TC oil seals or TG4 oil seals, it is crucial to understand your application environment and requirements. TC oil seals are suitable for compact spaces and general sealing requirements, while TG4 oil seals perform better in harsh environments with high demands. It is recommended to work with professional engineers and manufacturers to ensure the selection of the most suitable oil seal product, thereby enhancing equipment reliability and safety.

Double lip design: TC Oil Seal features a double lip structure, with the main lip used for oil sealing and the secondary lip for dust prevention. This design makes it more effective in preventing oil leakage and protecting the sealed components from dust and other contaminants, enhancing the overall sealing performance and extending the service life of the equipment12.

Rubber-covered outer diameter: The outer diameter of the TC Oil Seal is completely covered by rubber, which improves the sealing ability between the outer diameter of the seal and the installation bore, preventing oil from seeping out along the outer diameter of the seal1.
Self-tightening spring: It is equipped with a self-tightening spring, which can provide a certain amount of radial force to ensure that the lip of the seal closely adheres to the rotating shaft, thereby achieving better sealing under different operating conditions such as varying pressures and speeds1.
Good sealing performance: The combination of the double lip, rubber-covered outer diameter, and self-tightening spring enables the TC Oil Seal to effectively prevent oil leakage, even in relatively harsh working environments with vibrations, temperature changes, and pressure fluctuations, ensuring the normal operation of the equipment and reducing the frequency of maintenance and oil replacement.
Wide range of applications: It can be used in various mechanical equipment that requires oil sealing, such as engines, transmissions, axles, and hydraulic systems. It is suitable for sealing different types of lubricating oils and working under different rotational speeds and pressures, demonstrating strong versatility12.
Reasonable cost-effectiveness: Compared with some other high-end or special sealing components, TC Oil Seal has a relatively simple structure and is easy to manufacture, so its cost is relatively low. At the same time, it can provide reliable sealing performance within a certain range of working conditions, making it a cost-effective choice for many general industrial applications12.
Nitrile rubber: It has good resistance to heat, wear, and various lubricating oils, grease, and oil-gas mixtures. It is suitable for use in a temperature range of -30°C to 120°C and is widely used due to its relatively low cost1.
Fluorine rubber: With excellent resistance to aging, heat, and oil, it can be used in almost all lubricating oils, fuel oils, and gasoline. It is not easily hardened in oils containing extreme pressure additives, but its cold resistance and high-temperature wear resistance are relatively poor, and the permanent compression deformation is relatively large. The applicable temperature range is -20°C to 250°C1.
Silicone rubber: It has outstanding resistance to high and low temperatures, can be used for an extremely long time at 150°C without performance changes, and can be continuously used for 10,000 hours at 200°C. It can maintain its unique elasticity, ozone resistance, and weather resistance within the working temperature range of -70°C to 260°C1.
