Tanged Metal Reinforced Graphite Gasket Manufacturer & Supplier in China
Kaxite KXT 710 is a high-performance tanged metal reinforced graphite gasket made by mechanically bonding flexible graphite layers with a tanged metal sheet, metal mesh, or metal foil. No adhesives are used in the composite structure, giving the gasket excellent dimensional stability, easy handling, and reliable sealing under high pressure, high temperature, and aggressive chemical media.
It is a practical choice for pipeline flange sealing, chemical manufacturing, valves and pumps, pressure vessels, heat exchangers, and other critical industrial sealing points. The tanged metal core provides mechanical strength and blow-out resistance, while the graphite surface offers self-lubrication, thermal stability, and chemical resistance.
Why Buyers Choose This Gasket
High-Temperature Sealing
Suitable for steam service up to 650°C, with excellent thermal stability, low aging, and long service life under extreme conditions.
High-Pressure Performance
The metal reinforcement provides pressure resistance and dimensional stability under bolt load, even during pressure fluctuations.
Chemical Resistance
Flexible graphite resists many aggressive chemicals, making it ideal for chemical, petrochemical, and process industry applications.
Easy Installation
Strong composite construction without adhesives; available with or without eyelets for easier handling and fitting on site.
Reliable Under Fluctuation
Seals easily under moderate bolt loads and retains torque through service, maintaining tightness during pressure and temperature cycling.
Customizable Supply
Metal reinforcement type, thickness, size, and flange standard can be produced to your drawing or specific application requirement.
Typical Applications
Material Options and Sealing Performance
The gasket can be supplied with different metal reinforcement materials. The table below helps buyers select the right grade based on pressure, compressibility, and recovery requirements.
| Reinforced Material | Pressure | Compressibility | Recovery |
| Tanged Carbon Steel Sheet | ≥48N/MM2 | 30-35% | 15-20% |
| SS304/SS316 Tanged Sheet | ≥48N/MM2 | 30-35% | 15-30% |
| SS304/SS316 Flat Sheet | ≥48N/MM2 | 30-40% | 10-15% |
| SS304/316 Mesh Sheet | ≥48N/MM2 | 40-50% | 15-20% |
| Tin-plated Tanged Sheet | ≥48N/MM2 | 25-30% | 10-15% |
For more demanding sealing conditions, the following gas permeability and sealing constants can be used for engineering reference.
| Reinforced Material | Gas Permeability (cm3/min)(t=1.5mm) | Sealing Quality(t=1.5mm) | Sealing Constant | ||
| N2 m1/hr | Bumming oil A m1/hr | "M" | "Y" v | ||
| Tanged Carbon Steel Sheet | <=0.8 | 30 | <0.5 | 3.0 | 9000 |
| SS304/SS316 Tanged Sheet | <=0.8 | 60 | <0.5 | 2.5 | 4000 |
| SS304/SS316 Flat Sheet | <=0.4 | 35 | <0.5 | 2.0 | 900 |
| SS304/316 Mesh Sheet | ≥1.0 | 70 | <0.5 | 3.0 | 5000 |
Buyer note: Final material selection depends on operating temperature, pressure, media, flange standard, and bolt load. Please share your flange size, pressure, temperature, and process media for a fast technical recommendation.

What is a tanged metal reinforced graphite gasket?
It is a composite gasket made of flexible graphite mechanically bonded to a tanged metal sheet, mesh, or foil. The metal tangs lock the graphite layers together without adhesives, providing strength, dimensional stability, and reliable sealing.
What is the maximum temperature?
It offers excellent thermal stability and can be used in steam service up to 650°C. The actual limit depends on the metal reinforcement, media, pressure, and installation conditions.
Which industries use this gasket?
It is widely used in chemical manufacturing, petrochemical, power plants, valves and pumps, pressure vessels, heat exchangers, and pipeline flange sealing.
Can you produce custom sizes?
Yes. We can produce standard flange sizes and custom gaskets according to your drawing, including special dimensions, thicknesses, and eyelet options.
How do I choose the metal reinforcement?
Selection depends on temperature, pressure, chemical media, and flange conditions. SS304/SS316 tanged sheet is common for general corrosive service; carbon steel tanged sheet is cost-effective for many standard applications; tin-plated and mesh options are available for specific requirements.
What information is needed for a quotation?
Please provide flange size and standard, pressure, temperature, media, required metal reinforcement, thickness, quantity, and delivery target. A drawing or sample helps us confirm faster.
