Graphite Gasket Reinforced With Metal Foil – High-Temperature Sealing for Demanding Applications
Kaxite Sealing, a leading China graphite gasket reinforced with metal foil manufacturer, offers premium metal foil reinforced graphite gaskets engineered for extreme sealing performance in high-temperature, high-pressure, and chemically aggressive environments. By laminating high-purity flexible graphite with a corrosion-resistant metal foil (stainless steel, titanium, or other alloys), this composite gasket combines the exceptional thermal stability, self-lubrication, and chemical resistance of graphite with the mechanical strength and dimensional stability of metal. The result is a tough, versatile sealing solution that withstands temperatures up to 650 °C in steam and pressures exceeding 100 bar, ensuring reliable sealing in flanges, heat exchangers, valves, and pressure vessels across the petrochemical, power generation, refining, and chemical processing industries.
What sets Kaxite apart? As a professional graphite gasket reinforced with metal foil supplier in China, we utilize advanced lamination and die-cutting technologies to ensure uniform graphite density and precise metal foil bonding. Our reinforced graphite gaskets are manufactured from purified natural graphite flakes and mechanically bonded to the metal foil using a proprietary process that eliminates adhesives, preventing outgassing and ensuring long-term stability. Each production lot undergoes rigorous testing for density, compression, recovery, and thermal cycling to guarantee consistent performance in your most critical applications. Our ISO 9001:2015 certified facility ensures every gasket meets the highest quality standards.
With our custom OEM capabilities, we supply graphite gaskets reinforced with metal foil in virtually any size and shape – from standard ASME/ANSI flange gaskets to complex custom configurations.

Frequently Asked Questions
- Q: What is a graphite gasket reinforced with metal foil and why is it better than plain graphite?
- A: This is a composite gasket that combines high-purity flexible graphite with a thin metal foil (typically stainless steel). The metal foil provides mechanical reinforcement, giving the gasket handling strength, blowout resistance, and dimensional stability under high pressures and temperature fluctuations. Unlike plain graphite, which can be fragile and prone to extrusion, the metal foil reinforced version offers superior robustness while retaining graphite's excellent sealing properties, self-lubrication, and chemical resistance. It is ideal for high-temperature (up to 650 °C in steam) and high-pressure applications where reliability is critical.
- Q: What metal foil materials are available?
- A: We offer a range of metal foils including Stainless Steel 316L, 304, Titanium, Monel, and Inconel. The choice depends on your service conditions – SS316L is the most common for general corrosive and high-temperature applications, while Titanium and Inconel are recommended for extremely aggressive environments. Contact us for assistance in selecting the right metal foil for your specific media and temperature.
- Q: What is the maximum operating temperature?
- A: In steam or inert atmospheres, the gasket can operate continuously from –200 °C to +650 °C. In oxidising atmospheres, the maximum temperature is 450 °C to prevent graphite oxidation. Short-term excursions above these limits may be tolerated, but we recommend consulting our technical team for your specific application.
- Q: What sizes and shapes are available?
- A: We manufacture gaskets in virtually any size and shape – round, oval, rectangular, or complex custom profiles. Thicknesses typically range from 1.5 mm to 5.0 mm (up to 10 mm on request). We can also add eyelets (bolt holes) for easier centering. Send us your flange details for a quick quotation and competitive China factory pricing.
- Q: Is this gasket suitable for use with aggressive chemicals?
- A: Yes. Graphite offers excellent resistance to a wide range of chemicals, including acids, alkalis, solvents, hydrocarbons, and steam. It is generally suitable for pH 0–14, with the exception of strong oxidizers such as concentrated nitric acid or oxygen at elevated temperatures. The metal foil should also be chosen based on chemical compatibility – stainless steel and titanium are generally excellent choices. Our technical team can provide specific chemical resistance guidance.
- Q: Do you provide samples before bulk orders?
- A: Absolutely. We supply free material samples for you to evaluate quality, compression, and sealing performance on your specific flange conditions. Request a free sample – sample orders are processed within 3–5 working days from our China factory.
