Product Description
The offered white PTFE (Polytetrafluoroethylene) washer has a great resistance to elevated pressures and temperatures. Besides, it is entirely protected from oil, fuel, alkalis, and acids. It also has a low flammability property. This is a cost-savvy alternative when the application needs shim, spacer or different reinforcement. It is ideal for elevated temperature conditions and for different applications, which meet industry specifications and have the feasibility for surface wear. Our white PTFE washer has a standard size that corresponds to matching bolt or screw size. This has similar qualities to Polytetrafluoroethylene Washer, including a highly low friction coefficient. It does not adhere to different materials and effectively opposes surface wear.
PTFE Washer Advantages:
- Have great compression and tensile strength
- Effectively distributes threaded fastener load
- Utilized as locking devices, shims, spacers, and springs
- External diameter is twice than the internal diameter

FAQs of White PTFE Washer:
Q: How can the white PTFE washer be customized for specific applications?
A: The PTFE washer can be tailored in both outer diameter (from 5 mm to 200 mm) and thickness (between 1 mm and 10 mm), allowing you to specify the exact dimensions required for your sealing or insulation needs.
Q: What environments are white PTFE washers most suitable for?
A: These washers are ideal for use in aggressive chemical environments, electrical applications requiring high dielectric strength, and operations involving extreme temperatures from -200C to +260C.
Q: When should PTFE washers be chosen over other washer materials?
A: PTFE washers are preferred when superior chemical resistance, low friction, non-stick characteristics, and excellent insulation properties are required, especially in settings where other materials may degrade or absorb moisture.
Q: Where are white PTFE washers commonly utilized?
A: They are extensively used in industries such as chemical processing, electronics, pharmaceuticals, and food processing for applications involving sealing, electrical insulation, and protection against corrosive chemicals.
Q: What is the typical process for installing a PTFE washer?
A: PTFE washers are installed by placing them between two surfaces to provide a tight seal, reduce friction, or offer insulation. Their flexibility and smooth finish facilitate easy handling during assembly.
Q: What are the primary benefits of choosing white PTFE washers?
A: The key advantages include high chemical and thermal resistance, non-absorbency, excellent dielectric strength, long-term durability, and customizable sizing, making them versatile for diverse industrial applications.
