The metal outer ring, typically made of stainless steel, carbon steel, or copper, provides structural strength and resistance to high pressure, while the inner rubber ring—made from NBR, FKM, EPDM, or silicone—offers excellent elasticity, sealing performance, and chemical resistance.Combination gaskets are specially designed to provide reliable static sealing in threaded joints, bolt connections, and hydraulic fittings, effectively preventing leakage of fluids such as oil, gas, and water. The unique bonded structure ensures that the gasket remains stable under high pressure and high temperature conditions, while also resisting extrusion, corrosion, and deformation over time.Key Advantages of Combination Gaskets:Excellent sealing performance under high pressure and temperatureDurable and reusable with stable structure and long service lifeAvailable in various sizes and materials to suit diverse industrial needsSupports custom OEM production for non-standard specificationsEasy to install and compatible with standard bolts, flanges, and pipe fittingsApplications:Combination gaskets are widely used across industries such as:Automotive and heavy trucks (engine, transmission, fuel systems)Hydraulic and pneumatic systemsConstruction machineryOil & gas pipelines and chemical processing equipmentAerospace components and fluid delivery systemsHousehold appliances and plumbing hardwareWith their metal-rubber hybrid construction, combination gaskets have become an indispensable component in sealing applications that demand both strength and flexibility. Whether used in industrial maintenance, OEM production lines, or high-performance engineering environments, they offer cost-effective and reliable sealing solutions.Product DescriptionCompany ProfileFAQFAQ1.Why are more and more customers choosing Xingtai Zhengmai Rubber Technology Co., Ltd.?We specialize in manufacturing and exporting high-quality sealing products.
