Metal Jacketed Gasket Materials
To provide a reliable seal, these gaskets utilize a composite construction that balances strength with flexibility. The metal jacket serves as the outer protective shell, providing the necessary structural integrity and acting as the primary defense against the process media and high pressures. This shell is typically manufactured from alloys like Stainless Steel, Carbon Steel, or Monel, chosen to match the chemical and thermal demands of the application. In contrast, the filler core sits inside the jacket to provide the “spring” and compressibility required to conform to flange surfaces and create a tight, lasting seal. By using resilient materials such as Flexible Graphite, PTFE, or Ceramic, the filler compensates for thermal expansion and mechanical vibrations 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.
PTFE (Teflon)
Used specifically for high-purity or highly aggressive chemical environments where temperature remains below 260°C.
Ceramic Fiber
Reserved for extremely high-temperature applications (up to 1100°C) where other fillers would degrade.
Non-Asbestos Millboard
A cost-effective, general-purpose filler used for heat insulation and lower-pressure sealing up to 500°C.

- Double-jacketed gaskets are also extensively used in standard flanges where the service is not critical
- Since most double-jacketed gaskets are custom made, there is virtually no limit to size, shape or configuration in which these gaskets can be made
Double Jacketed Corrugated Gasket
- The double-jacketed corrugated gasket is an improvement on a plain-jacketed gasket
- The corrugations on the gasket will provide an additional labyrinth seal
- Provides the advantage of reducing the contact area of the gasket, enhancing its compressive characteristics
- A double-jacketed corrugated gasket still relies on the primary seal on the inner lap
Corrugated Metal Gaskets [CMG]
- The Corrugated Metal Gaskets family of products are the standard in respect to corrugated metal gasket technology
- These gaskets are an excellent choice for 150 and 300 class ASME flanges where available bolt loading is minimal
- The substrate geometry promotes recovery and resilience through thermal cycles and extended service life
- Corrugated Metal Gaskets can be direct replacements for Spiral Wound Gaskets
- Eliminates inward buckling issues while creating a seal at moderate flange stresses
Single Jacketed
- Constructed of soft filler completely enclosed in a single jacket
- Ideal for applications where the width does not permit the use of a double-jacketed gasket

Answers to all your possible questions.
When should I choose a Double Jacketed Gasket over a Spiral Wound Gasket?
Double Jacketed Gaskets are typically preferred for heat exchangers with complex pass partition bars and large diameters where a narrow sealing width is required. While Spiral Wound Gaskets offer better recovery, Double Jacketed types are easier to custom-fabricate into non-circular shapes and are often more cost-effective for large-scale equipment.
Can these gaskets be used on uneven or old flange surfaces?
Yes, particularly the Double Jacketed Corrugated or Copper-jacketed versions. The soft filler and corrugated metal profile allow the gasket to conform better to minor flange irregularities than a standard flat metal gasket, though high seating stress is still required for a perfect seal.
What configurations are available for your metal jacketed gaskets?
Our metal jacketed gaskets offer versatility in manufacturing with the ability to adopt various configurations. These gaskets commonly incorporate a non-asbestos, high-temperature gasket material filler suitable for applications reaching up to 900°F (482°C). For elevated temperatures or specific applications, alternative soft fillers are also accessible. The standard metals utilized in crafting jacketed gaskets include aluminum, copper, brass steel, nickel, Monel®, Inconel®, and stainless steel variations such as types 304, 316, 321, 347, and 410. The selection of jacket metal is contingent upon the specific service conditions encountered.
How do I choose the right jacket material for corrosive media?
Material selection depends on the chemical concentration and temperature. For example, Stainless Steel 316L is excellent for general corrosion, while Monel 400 is preferred for hydrofluoric acid or seawater, and Inconel is best for high-temperature oxidation. Our technical team can help you match the alloy to your specific media.
Are your Metal Jacketed Gaskets compliant with international standards?
Absolutely. We manufacture all gaskets to meet or exceed ASME B16.20, ASME B16.5, and ASME B16.47 standards, ensuring dimensional accuracy and safety for high-pressure industrial use.
What information is needed to provide a quote for a custom heat exchanger gasket?
To provide an accurate quote, we typically require the outer diameter (OD), inner diameter (ID), thickness, the specific metal/filler materials, and a drawing or description of the pass partition bar configuration.
