- The importance of using the right type of spark plug cannot be overstated. Different engines require specific heat ranges, electrode types, and thread sizes. Using the incorrect plug can lead to pre-ignition, where the air-fuel mixture ignites before the piston reaches top dead center, causing engine knocking and potential damage. It can also result in increased fuel consumption and higher emissions, contradicting modern efforts towards environmental sustainability.
- One of the key factors that determine the effectiveness of an oil seal is its material composition. Common materials used in oil seals include rubber, fluoropolymer, and synthetic materials like PTFE (polytetrafluoroethylene). Each material offers unique properties that make it suitable for specific applications. For instance, rubber seals are known for their flexibility and resistance to oil and heat, making them ideal for low-pressure environments. On the other hand, PTFE seals are highly durable and resistant to extreme temperatures and chemicals, making them suitable for high-pressure and harsh conditions.

JTEKT provides special seals for use in a wide variety of machines and applications.
Table 5 lists the major special seals, their shapes, and their features.Oil seals are used for essential applications in the oil, gas and petrochemical sectors. They are created to avoid leaks from the sealing lip and rotary shaft by forming a thin layer of oil between them. Oil seals could be developed using well-known sealing materials, involving NBR, EPDM, PolyTetraFluoroEthylene (PTFE), Silicone,and fluoroelastomer.
Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.
The metal case serves as the oil seal’s exterior or frame, providing rigidity and strength to the seal. The case material selection depends on the environment in which the seal will operate. Often, the same rubber material used in the seal element covers the case to help seal the exterior of the oil seal in the housing bore.
- In conclusion, PU oil seals are a testament to the power of material innovation in solving engineering challenges. Their superior properties, resistance to harsh environments, and adaptability make them a go-to choice for engineers seeking reliable sealing solutions. As technology continues to evolve, we can expect further advancements in the design and application of PU oil seals, contributing to increased efficiency and reliability in industrial operations.
