What Are the Key Materials of Stamping Jacket Gaskets?

The materials used in our Stamping Jacket Gaskets from Ningbo Kaxite Sealing Materials Co., Ltd are carefully selected to withstand harsh operational environments. Our gaskets combine metals and soft fillers to balance strength and flexibility. 


Here are the key components:

  • Outer Ring Material: High-grade stainless steel 304 or 316 ensures corrosion resistance and mechanical strength, even under fluctuating temperatures.
  • Inner Filler Material: Graphite, PTFE, or ceramic fiber is used to provide compressibility and excellent sealing capabilities.
  • Surface Coating: Optional coatings, such as nickel plating or anti-corrosion treatments, enhance chemical resistance and extend service life.


Our factory ensures every batch of Stamping Jacket Gaskets meets stringent ISO quality standards. Below is a detailed parameter table for reference:

Parameter Specification Performance Benefit
Outer Ring Material Stainless Steel 304/316 High mechanical strength and corrosion resistance
Inner Filler Graphite/PTFE/Ceramic Fiber Excellent compressibility and sealing performance
Temperature Range -100°C to 600°C Suitable for high-temperature heat exchangers
Pressure Resistance Up to 25 MPa Ensures reliability in high-pressure applications
Surface Treatment Nickel plating / Anti-corrosion coating Enhances chemical and environmental resistance

How Do Design Features of Stamping Jacket Gaskets Contribute to Sealing?

The design of our Stamping Jacket Gaskets plays a critical role in ensuring effective sealing in heat exchangers. At Kaxite Sealing, we focus on precision stamping and optimal geometry to improve gasket performance:


  • Uniform Compression: The stamped metal jacket distributes stress evenly across the gasket, preventing leaks due to uneven pressure.
  • Enhanced Elastic Recovery: Our inner filler material compresses and recovers effectively, maintaining a tight seal even after repeated thermal cycles.
  • Multi-Layer Construction: Multiple layers of metal and filler enhance sealing under dynamic operating conditions.
  • Customizable Geometry: We provide gaskets in various shapes, including round, oval, and custom profiles, to ensure perfect fit in complex heat exchanger designs.
  • Reinforced Edge Design: The edges are reinforced to prevent extrusion or damage under high pressure.


Our Stamping Jacket Gaskets are tested in simulated operational environments, and the results show consistent sealing performance and long service life, even under high-pressure and high-temperature conditions.


Why Is Precision Manufacturing Critical for Sealing Performance?

Precision manufacturing is essential to guarantee the quality and performance of Stamping Jacket Gaskets. At Ningbo Kaxite Sealing Materials Co., Ltd, our factory employs advanced stamping, cutting, and assembly techniques to ensure every gasket meets exact specifications:


  • Dimensional Accuracy: Tight tolerances prevent gaps and misalignment, ensuring a uniform seal.
  • Surface Finish: Smooth metal surfaces reduce friction and wear while enhancing filler adhesion.
  • Consistent Material Distribution: Uniform filler placement improves compressibility and prevents leakage paths.
  • Quality Control: Each gasket is inspected for defects, material composition, and pressure resistance, guaranteeing reliability in demanding heat exchanger applications.


Our factory integrates automated stamping lines and real-time monitoring to maintain high consistency. By focusing on precision manufacturing, our Stamping Jacket Gaskets deliver reliable sealing performance and extended service life.


How Do Stamping Jacket Gaskets Perform Under Extreme Conditions?

Heat exchangers often operate under extreme temperature fluctuations, high pressure, and chemically aggressive environments. Our Stamping Jacket Gaskets are engineered to withstand these challenges:


  • High-Temperature Resistance: Our gaskets maintain structural integrity and sealing capacity up to 600°C.
  • Chemical Resistance: Graphite and PTFE fillers resist acids, alkalis, and solvents, preventing degradation over time.
  • Pressure Endurance: The metal jacket prevents extrusion of the filler, ensuring leak-free operation at pressures up to 25 MPa.
  • Thermal Cycling Capability: Our gaskets recover their shape after repeated heating and cooling cycles, preventing performance loss.
  • Longevity: Corrosion-resistant materials and reinforced designs minimize maintenance and replacement frequency.


By combining advanced material selection with robust design, our Stamping Jacket Gaskets from Ningbo Kaxite Sealing Materials Co., Ltd deliver long-term performance in even the most demanding heat exchanger applications.
