PTFE washers are versatile components used in various industries due to their chemical resistance, low friction, and thermal stability. They are available in a wide range of sizes and thicknesses to accommodate different applications. The diameter of PTFE washers typically ranges from 0.093 inches (about 2.36 mm) to 16 inches (about 406 mm), while thicknesses can vary from as thin as 0.0002 inches (about 0.005 mm) up to 0.125 inches (about 3.175 mm). Metric sizes are also commonly available, including 0.5mm to 12mm in thickness. Custom sizes can often be produced for specialized needs.
Key Points Explained:
-
Diameter Range:
- PTFE washers are available in diameters from 0.093 inches (2.36 mm) to 16 inches (406 mm). This broad range makes them suitable for applications requiring very small washers (e.g., precision instruments) to large washers (e.g., industrial machinery).
- Metric equivalents are also widely available, with common sizes like 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 6mm, 8mm, 10mm, and 12mm.
-
Thickness Range:
- Thickness options span from 0.0002 inches (0.005 mm) to 0.125 inches (3.175 mm). Ultra-thin washers are ideal for delicate applications where minimal material is needed, while thicker washers provide durability for high-pressure or high-wear environments.
- Metric thicknesses align with the inch-based options, ensuring compatibility with global standards.
-
Customization and Availability:
- While standard sizes are readily available, manufacturers often offer custom sizes for specialized applications. For example, large quantities or unique dimensions can be made-to-order, similar to the flexibility seen with PTFE brush production.
- Stock availability may vary, so it’s advisable to confirm with suppliers for specific requirements.
-
Applications and Selection Considerations:
- Small diameters and thin washers are often used in electronics, medical devices, or precision equipment where space and weight are critical.
- Larger diameters and thicker washers are common in industrial settings, such as chemical processing or heavy machinery, where durability and chemical resistance are paramount.
- When selecting a washer, consider the load, temperature, and chemical exposure to ensure the chosen size and thickness meet performance needs.
-
Material Advantages:
- PTFE’s non-stick properties and resistance to extreme temperatures (-200°C to +260°C) make these washers suitable for harsh environments.
- Their low friction reduces wear in dynamic applications, extending the lifespan of assemblies.
For purchasers, understanding these size and thickness ranges ensures the right washer is selected for the job, balancing cost, performance, and availability. Always verify with suppliers for specific tolerances or custom requirements.
