Gaskets

In modern industrial systems, sealing reliability is a key factor in ensuring operational stability, particularly in environments where pressure, temperature, and chemical resistance intersect. One solution that has gained attention across sectors such as automotive, hydraulic, and petrochemical is the Combination Gasket Seal—a component that integrates metal and elastomer materials to provide multi-functional sealing performance. Rather than relying on single-material gaskets, Bonded Seals are designed to offer both structural support and flexible sealing in a single unit. Typically, these products consist of a metal washer or frame—often carbon steel, stainless steel, or brass—bonded to a layer of rubber material like NBR (nitrile rubber), FKM (fluoroelastomer), or EPDM, depending on the medium and environment. Where Are Combination Gasket Seals Used? These seals are commonly used in: Hydraulic pipe connections, especially in mobile equipment or compact manifolds Automotive fluid systems, including fuel injection components and transmission housing High-pressure gas systems where vibration or surface irregularities may cause conventional seals to fail Oil and gas flange interfaces that require both sealing and mechanical retention Their versatility makes them a suitable choice for sealing static interfaces that must remain leak-free under pressure without relying on external sealing compounds. Key Benefits and Performance Features Dual-sealing capability: The metal component ensures stability and pressure resistance, while the rubber layer provides conformity and adaptability to surface imperfections. Easy installation: Most combination gasket seals are designed for drop-in use, eliminating the need for additional sealants or surface preparation. Material flexibility: Manufacturers can select rubber grades tailored for oil, fuel, water, or aggressive chemicals, offering compatibility across various industries. Temperature tolerance: Depending on the elastomer used, seals can operate in a wide temperature range with minimal performance degradation. Reduced maintenance: A proper combination seal reduces the likelihood of leaks over time, lowering maintenance needs and replacement frequency. Customization and Quality Control Many Chinese and international manufacturers now offer custom-designed combination gaskets for specific pressure ratings, flange sizes, or material requirements. Whether the client needs a specific durometer hardness, thickness, or groove fitment, custom production is often available after prototype validation. During manufacturing, strict quality control procedures—including dimensional inspections, material tests, and compression set analysis—are conducted to ensure product consistency and performance integrity.
