PTFE Gasket Materials & Technical Specifications

PTFE (Polytetrafluoroethylene) gaskets are engineered from one of the most chemically resistant and thermally stable materials available today. Ideal for OEMs, industrial manufacturers, and maintenance teams, PTFE gasket materials offer a superior sealing solution for extreme environments, aggressive chemicals, and sensitive operations like pharmaceuticals or food-grade processes.

Whether you’re sourcing for bulk supply, custom fabrication, or replacement parts, understanding the material grades and technical specs of PTFE gaskets helps you choose the right product that ensures safety, compliance, and long-term reliability.

Material Type	Temperature Range	PN (Pressure Nominal) Range	Applications
Virgin PTFE (Pure Teflon)	-200°C to +260°C	Up to PN 40	Food, Pharma, Medical (FDA compliant)
Glass-Filled PTFE	-200°C to +250°C	Up to PN 63	Chemical plants, Steam, High-pressure systems
Carbon-Filled PTFE	-200°C to +260°C	Up to PN 100	High-load equipment, Oil & Gas, Petrochemical
Bronze-Filled PTFE	-180°C to +240°C	Up to PN 40	Compressors, Pumps, Mechanical assemblies
Expanded PTFE (ePTFE)	-268°C to +260°C	Up to PN 160	Cryogenics, Cleanrooms, Vacuum sealing

Why Material Selection Matters

• • Virgin PTFE is ideal when purity and non-contamination are key, especially in food or pharmaceutical processing lines.
  • Filled PTFE (glass, carbon, bronze) enhances mechanical strength, wear resistance, and pressure handling — great for heavy industrial applications.

• • ePTFE is known for its flexibility and sealing performance even on damaged or uneven flanges.

We offer custom-cut PTFE gaskets using these high-performance materials for your exact pressure-temperature requirements. All gaskets are FDA, ISO, and RoHS compliant, ensuring reliability and global compliance.

Applications of PTFE Gaskets Across Industries

PTFE gaskets are used everywhere because they are robust and dependable. The gaskets are needed for the smooth running of machines. The common uses of PTFE gaskets include the following:

• Factories: A PTFE gasket is here used by the machine so that parts are prevented from destruction that occurs due to heat and chemicals. The machine is thus safer to use and operates properly.
• Plumbing: PTFE gaskets are applied inside and within pipes to prevent leakage. They are very helpful in plumbing due to their compatibility with water and different fluids.
• Food Industry: PTFE gaskets are non-toxic and harmless to food; thus, they can be safely used with food. They make the machines in the food industry move smoothly and are quite easy to clean. Hence, they are an excellent choice for food factories.
• Medical Equipment: In a hospital and laboratory, PTFE gaskets are used in equipment since it does not react with chemicals; hence ensuring the safety and clean technology of the equipment used for medical purposes.

PTFE gaskets offer unmatched performance across sectors—from food-grade systems and medical devices to chemical manufacturing and high-temperature pipelines — making them an indispensable choice for industrial sealing solutions.

Available Types of PTFE Gaskets for Every Requirement

There are different kinds of PTFE gaskets, according to what they are designed for. We  provide a selection from which you can get the option fitting your need. Here are the kinds of PTFE gaskets you can get:

• Full-Face Gasket: It covers the full outer area of the flange and is primarily used in large-sized pipes. Full-face gaskets are very effective for sealing wide pipes and preventing leakage.
• Ring Gasket: This is a gasket having the appearance of a ring; it is placed in small diameter pipes. This helps it seal up gaps where leakage may occur and prevents them from happening.
• Envelope Gasket: They have another layer of protective cover, and thus are much more rugged. They are pretty useful where the usage calls for harsh chemicals, like the plants used in manufacturing.
• Custom Gaskets: We can make a gasket in any shape or size. This is useful when a special type of gasket is needed for an uncommon job.
