Gaskets
Choosing the Right Materials, Ensuring Maximum Performance
The performance of a gasket depends on the properties of the filler material, metal wrapping, and support ring used.
The correct material selection should be made considering factors such as operating temperature, pressure, and chemical environment.
At Positive Steel, we offer a wide range of materials to suit different application needs.
FILLER MATERIALS
These are the essential components that directly affect the sealing performance of the gasket.
Pure Graphite
The most commonly used filler material in high-temperature and chemical environments.
✔ High heat resistance
✔ Chemical resistance
✔ Industrial standard use
PTFE (Teflon)
The preferred filler material in aggressive chemicals and acidic environments.
✔ Chemical resistance
✔ Low friction
✔ Acid and solvent applications
Mica / Graphite
A special filler material used in applications requiring extreme temperatures.
✔ Very high heat resistance
✔ Thermal stability
✔ Special industrial applications
Ceramic
A special filler material used in systems requiring high insulation.
✔ Thermal Insulation
✔ Special Application Areas
✔ High Temperature Resistance
METAL WINDINGS AND RINGS
Brief Description
These are the metal components that provide the mechanical strength of the gasket.
Stainless Steels (304, 304L, 316L, 321)
These are materials with high corrosion resistance, preferred in general industrial use.
✔ Corrosion Resistance
✔ Long Service Life
✔ Wide Range of Applications
Special Alloys (Monel, Inconel, Hastelloy, Titanium)
These are high-performance alloys developed for harsh chemical and marine environments.
✔ High Chemical Resistance
✔ Seawater and Acidic Environment Compatibility
✔ Critical Applications
Outer Ring Material
Made from carbon steel or stainless steel.
✔ Epoxy painted / galvanized options
✔ Provides mechanical strength
✔ Long service life
