A combination gasket is a type of sealing element made up of two or more components, designed to provide a reliable and efficient seal in various mechanical applications. Each component of the combined seal typically includes a primary seal and an auxiliary seal. The most common form of a combination seal consists of a primary sealing ring along with an elastomer, a retaining ring, or a guide ring. This kind of seal is often referred to as an extrusion-type seal due to its design that prevents material extrusion under pressure.
These seals are widely used in hydraulic and pneumatic systems where high performance and durability are essential. The materials commonly used include rubber, polytetrafluoroethylene (PTFE), polyurethane, polyoxymethylene (POM), nylon, and phenolic resin. These materials are selected for their excellent elasticity, wear resistance, and ability to withstand deformation under pressure.
One of the key advantages of combination seals is their compact structure, which helps save installation space and reduces overall system complexity. They also offer low frictional resistance, making them ideal for dynamic applications where movement is involved. Additionally, they have a self-sealing effect, meaning they can compensate for wear over time, ensuring long-term reliability.
The working principle of a combination gasket relies on the elastic force generated when the seal is compressed. This force allows the primary sealing ring to maintain contact with the metal surface, creating a tight seal. At low pressures, the seal is maintained through the pre-tightening force of the elastomer. As the pressure increases, the sealing effectiveness automatically improves, making it suitable for both low- and high-pressure environments.
To achieve optimal performance, the design of the seal must be carefully engineered, and the materials must possess high elasticity, good resistance to permanent deformation, and strong anti-extrusion properties. The use of a stress distribution diagram in the design process helps ensure even pressure distribution across the sealing interface, enhancing the overall effectiveness of the seal.
