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:

Answers to all your possible questions.
What is a metal jacketed gasket?
A metal jacketed gasket is a semi-metallic sealing solution consisting of a soft filler core fully or partially enclosed in a metallic outer shell. The metal jacket provides strength and blowout resistance, while the filler ensures compressibility and recovery for effective flange sealing.
Where are metal jacketed gaskets commonly used?
Metal jacketed gaskets are primarily used in heat exchangers, boilers, pressure vessels, reactor systems, and refinery piping. They are ideal for high-temperature, high-pressure applications where conventional soft gaskets may fail.
What are the types of metal jacketed gaskets?
The main types include: 1. Single jacketed gaskets for moderate pressure services 2. Double jacketed gaskets for higher-pressure and heat exchanger applications 3. Corrugated metal jacketed gaskets for improved flexibility under fluctuating loads
What standards govern metal jacketed gaskets?
Metal jacketed gaskets are typically manufactured in accordance with ASME B16.20, DIN, and API standards , ensuring dimensional accuracy, pressure class compliance, and material traceability.
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.

Performance depends on material selection. With appropriate materials, metal jacketed gaskets can operate in temperatures exceeding 500°C and in high-pressure flange assemblies used in refinery and power generation systems.
How do metal jacketed gaskets differ from spiral wound gaskets?
Metal jacketed gaskets use a solid metal shell with a soft core, offering rigidity and suitability for heat exchanger and pass-partition applications. Spiral wound gaskets use alternating layers of metal winding and filler, making them more flexible and suitable for pipeline flanges.
How long do metal jacketed gaskets last?
Service life depends on operating conditions, but with proper installation and maintenance, they provide long-term sealing performance.
How should metal jacketed gaskets be installed?
Ensure clean flange surfaces, correct alignment, and uniform bolt tightening to prevent leakage.
