Advantages of Non Asbestos Gasket Paper S Series

The S Series products are part of our controlled swell product line, characterized by high compressive strength, excellent compressibility, and outstanding oil sealing performance under low flange pressures. These products are specifically designed for uneven flange surfaces, and cylinder head gaskets, and are ideal for oil pan applications and low surface pressure sealing system components.

Controlled Swell Technology: The S Series utilizes advanced controlled swell technology to ensure consistent and reliable sealing. This technology allows the material to swell in the presence of oil, enhancing the seal’s effectiveness without compromising the integrity of the sealing system.

High Compressive Strength: These products are engineered to withstand high levels of compression, making them robust enough to maintain their shape and functionality even under significant mechanical stress. This feature is crucial for applications requiring durable and long-lasting seals.

Excellent Compressibility: The S Series offers superior compressibility, allowing for better accommodation of surface irregularities and ensuring a tight seal. This characteristic is particularly beneficial for uneven flange surfaces, where achieving an effective seal can be challenging.

Outstanding Oil Sealing Performance: Designed with low flange pressure applications in mind, the S Series products provide exceptional oil sealing capabilities. This makes them suitable for a wide range of applications, including cylinder head gaskets and oil pan seals, where oil resistance is critical.

Ideal for Low Surface Pressure Sealing Systems: The controlled swell and compressibility features make the S Series particularly suitable for low-surface pressure sealing systems. These systems benefit from the material’s ability to adapt and seal effectively, even under minimal pressure, ensuring the integrity of the seal.
