PTFE Gaskets
PTFE Gaskets for chemical-resistant and high-performance sealing, widely used in chemical processing, pipelines, and industrial systems. Available in standard and custom sizes with OEM manufacturing support.
Product overview
Product details
PTFE (polytetrafluoroethylene) is a high-performance material known for its exceptional chemical stability and thermal resistance. PTFE gaskets provide reliable sealing in environments where traditional rubber materials may fail due to chemical attack or extreme temperatures.
They are widely used in environments involving corrosive media, high temperatures, and aggressive chemicals, ensuring long-term stability and leak prevention. Applications include chemical processing, petrochemical systems, pharmaceutical equipment, food processing equipment, and pipeline and flange sealing systems.
Key Features
- Excellent chemical and corrosion resistance
- Wide temperature resistance range (-200°C to +260°C)
- Non-stick and low friction surface
- Resistant to most acids, alkalis, and solvents
- Long service life in harsh environments
Technical Specifications
- Material: PTFE (Polytetrafluoroethylene)
- Temperature Range: -200°C to +260°C
- Pressure Resistance: Suitable for low to medium pressure applications
- Type: Flat gasket / expanded PTFE gasket
- Application: Static sealing
Size Range
Available in standard sizes and custom dimensions. Custom inner diameter (ID), outer diameter (OD), and thickness can be produced via CNC machining or die-cut.
Applications
- Chemical processing industry
- Petrochemical systems
- Pharmaceutical equipment
- Food processing equipment
- Pipeline and flange sealing systems
Material Advantages
PTFE is superior to rubber gaskets (such as NBR and EPDM) in chemical resistance, especially in corrosive environments. However, it has lower elasticity compared to rubber materials and is suitable for static sealing, not dynamic applications.
Customization
- Custom inner diameter (ID), outer diameter (OD), and thickness
- CNC machining for precise dimensions
- Expanded PTFE and filled PTFE options
- Custom packaging and private labeling
