Key Features & Benefits at a Glance

• Exceptional high-temperature performance – maintains structural integrity and function up to 500°F, ideal for demanding thermal environments.
• Superior chemical resistance – PTFE material resists a wide range of aggressive chemicals, preventing degradation and ensuring long-term reliability.
• Low friction and non-stick properties – reduces galling and sticking, facilitating easier assembly, disassembly, and maintenance.
• Reliable sealing and load distribution – precise dimensions (0.203" ID, 0.406" OD) for No. 10 screws ensure a proper fit and even pressure distribution.
• Durable and consistent performance – Durometer 55D hardness provides excellent resistance to deformation under load.
• Compliance with major environmental standards – meets RoHS 3 and REACH requirements, ensuring safety and regulatory acceptance.
• Corrosion and moisture immunity – PTFE construction is inherently resistant to rust and many corrosive agents, enhancing component lifespan.

Professional Applications & Engineering Value

This PTFE plastic flat washer is engineered to solve critical challenges in harsh industrial settings. Its high-temperature rating of 500°F makes it indispensable in applications like chemical processing, food and beverage equipment, and automotive systems where thermal stability is paramount. The inherent chemical resistance of PTFE (Teflon) ensures that the washer will not degrade when exposed to solvents, acids, or bases, protecting fastened joints from failure. The flat washer design and precise inch dimensions provide reliable load distribution and vibration resistance for No. 10 screws, preventing loosening and surface damage. Its white color and non-stick surface also make it suitable for clean and sanitary applications, offering long-term durability and reduced maintenance needs.
