Metal Jacketed Gasket Materials
To ensure dependable sealing performance, metal jacketed gaskets are manufactured using a composite construction that combines mechanical strength with controlled compressibility. The metal jacket functions as a protective outer shell, delivering structural support while acting as the primary barrier against process media and elevated pressures. Jacket materials are selected based on service conditions and commonly include Stainless Steel, Carbon Steel, and Monel to meet specific chemical and thermal requirements. Enclosed within the jacket, the filler core provides the necessary resilience and recovery to conform to flange surfaces and maintain a secure seal. Filler materials such as flexible graphite, PTFE, or ceramic help accommodate thermal expansion, vibration, and mechanical movement during operation.
Below is the complete list of available materials and their specific performance characteristics:
Ring gaskets are manufactured using various materials based on the application’s requirements. The material selection depends on factors such as the type of fluids being sealed, operating conditions (including temperature and pressure), and the overall environment. Here are some common materials used for manufacturing ring gaskets:
Soft Iron & Carbon Steel
An economical choice for general non-corrosive steam and oil services, suitable for temperatures up to 500°C.
Stainless Steel (304, 316L, 321)
The industry standard for chemical and food processing, offering high corrosion resistance at temperatures up to 550°C (with 321/347 reaching 800°C).
Copper & Brass
Soft and highly malleable materials ideal for uneven flange faces or air compressors, rated for temperatures between 300°C and 400°C.
Monel 400
Provides exceptional resistance to hydrofluoric acid and marine environments, maintaining integrity up to 500°C.
Inconel (600/625)
Engineered for the most demanding environments, providing superior oxidation resistance in extreme heat up to 1000°C.
Aluminum
A lightweight, corrosion-resistant option often used in specialized gas applications with temperatures up to 300°C.
Flexible Graphite
The most popular choice due to its wide temperature range (-200°C to 550°C) and excellent chemical resistance.

Answers to all your possible questions.
What is a metal jacketed gasket?
A metal jacketed gasket is a semi-metallic sealing element that combines a formed metal outer jacket with a compressible internal filler. The metal jacket provides structural support and blowout resistance, while the filler allows the gasket to conform to flange surfaces and maintain a seal under pressure, temperature changes, and mechanical loading. This construction makes it suitable for applications where soft gaskets lack strength and fully metallic gaskets lack flexibility.
When should I choose a Double Jacketed Gasket over a Spiral Wound Gasket?
A double jacketed gasket is preferred when applications involve high temperatures, large flange diameters, or limited bolt loads, such as heat exchangers and pressure vessels. Unlike spiral wound gaskets, metal jacketed gaskets provide better dimensional stability, resistance to blowout, and consistent sealing performance under thermal cycling and uneven flange conditions.
Can metal jacketed gaskets be used on uneven or old flange surfaces?
Yes. Metal jacketed gaskets are well-suited for uneven, warped, or aged flange surfaces. The soft internal filler allows the gasket to conform to surface irregularities while the metal jacket maintains structural integrity, making them a reliable choice for retrofit and maintenance applications.
What configurations are available for your metal jacketed gaskets?
Asian Sealing manufactures single jacketed gaskets, double jacketed gaskets, corrugated metal gaskets (CMG), and custom metal jacketed gaskets. Configurations can be tailored for heat exchangers, including large diameters, pass partition bars, and non-standard flange designs.
How do I choose the right metal jacketed gasket material for corrosive media?
Material selection depends on process media, operating temperature, and pressure conditions. Stainless steel and Monel jackets are commonly used for corrosive environments, while filler materials such as flexible graphite or PTFE enhance chemical resistance. Our engineering team supports the selection of metal jacketed gasket materials based on specific service requirements.
Are your metal jacketed gaskets compliant with international standards?
Yes. Asian Sealing manufactures ASME B16.20 metal jacketed gaskets and supplies products compliant with ASME B16.5 and ASME B16.47 flange standards. All gaskets are produced under certified quality systems with full material traceability for global industrial and oil & gas applications.
What information is required to quote a custom heat exchanger metal jacketed gasket?
To provide an accurate quote for a custom heat exchanger metal jacketed gasket, we require gasket dimensions, pressure class, operating temperature, process media, jacket and filler material preferences, and applicable standards. Drawings or existing gasket samples help ensure precise manufacturing and optimal sealing performance.
What is the difference between jacketed and double jacketed gaskets?
A jacketed gasket (single jacketed) consists of a soft filler enclosed by one metal jacket and is typically used where space constraints or moderate service conditions exist. A double jacketed gasket encloses the filler between two metal jackets or a jacket and insert, offering improved strength, better filler retention, and higher resistance to pressure and temperature. Double jacketed gaskets are widely used as metal jacketed gaskets for heat exchangers and high-duty industrial applications.
