Stephens Gaskets is a leading PTFE washers supplier, offering a wide range of thicknesses from 0.03mm to 6mm.

What Are PTFE Washers?

PTFE (Polytetrafluoroethylene) washers are precision-engineered sealing components known for their chemical resistance, temperature stability, and low-friction properties.

These washers provide exceptional durability and reliability in industries that require non-reactive and wear-resistant materials.

Whether you need thin washers for precision applications or thick washers for industrial sealing, we provide custom PTFE washers tailored to your specific needs.

PTFE Washer Thicknesses and Their Applications

1. Ultra-Thin PTFE Washers (0.03mm – 0.1mm)

Applications:

  • Fine-tuning clearances in microelectronics
  • Insulation layers in precision electrical components
  • Seals for low-pressure gas and fluid systems

Benefits:

  • Extremely flexible and lightweight
  • Ideal for tight-tolerance applications
  • Non-stick and chemically resistant
2. Thin PTFE Washers (0.2mm – 0.5mm)

Applications:

  • Sealing pneumatic and hydraulic systems
  • Wear-resistant layers in industrial machinery
  • Thermal insulation in high-temperature equipment

Benefits:

  • Moderate durability with enhanced flexibility
  • Resistant to chemical exposure and abrasion
  • Low friction for anti-wear applications
3. Medium PTFE Washers (0.7mm – 1.5mm)

Applications:

  • Standard gaskets for pipelines, pumps, and valves
  • Corrosion-resistant barriers in chemical processing equipment
  • Insulation layers for high-voltage electrical systems

Benefits:

  • Strong balance of flexibility and strength
  • Maintains sealing efficiency under mechanical stress
  • Suitable for dynamic applications
4. Thick PTFE Washers (2mm – 4mm)

Applications:

  • Heavy-duty sealing in industrial processing plants
  • Load-bearing insulation in power generation and refineries
  • High-pressure and high-temperature system components

Benefits:

  • Highly durable with superior mechanical strength
  • Withstands aggressive chemicals and temperature fluctuations
  • Provides long-term sealing with minimal maintenance
5. Extra-Thick PTFE Washers (5mm – 6mm)

Applications:

  • Structural insulation in industrial and electrical applications
  • Sealing high-pressure oil and gas pipelines
  • Load-bearing washers in heavy machinery and construction equipment

Benefits:

  • Maximum chemical and thermal resistance
  • Suitable for extreme mechanical loads
  • Long lifespan reduces maintenance costs

Challenges & Solutions for Using PTFE Washers

1. Low Mechanical Strength

  • Challenge: PTFE is softer than metal washers and may deform under high loads.
  • Solution: Reinforced PTFE washers with glass or carbon fillers improve mechanical strength.

2. Susceptibility to Creep & Cold Flow

  • Challenge: PTFE can deform over time under constant pressure.
  • Solution: Use metal-backed PTFE washers or reinforced grades for high-load applications.

3. High Initial Cost

  • Challenge: PTFE washers are more expensive than rubber or fiber washers.
  • Solution: Their long lifespan and minimal maintenance make them a cost-effective investment.

4. Limited Surface Compatibility

  • Challenge: PTFE requires smooth flange surfaces for optimal sealing.
  • Solution: Proper surface preparation or thicker PTFE washers can improve sealing efficiency.

FAQs About PTFE Washers

How do I select the right PTFE washer thickness?
Choose based on application pressure, temperature, and chemical exposure. Thin washers (0.03mm – 0.5mm) are ideal for precision sealing, while thicker washers (2mm – 6mm) work best for heavy-duty applications.
Are PTFE washers resistant to chemicals?
Yes, PTFE washers are chemically inert and can withstand acids, bases, and solvents, making them perfect for harsh industrial environments.
Can PTFE washers handle high temperatures?
