• Accurate thickness control (0.056-0.071") for uniform pressure application and vibration resistance in inch-based systems.
• Non-contaminating white PTFE construction that maintains purity in sensitive applications like food processing or pharmaceuticals.

Professional Applications & Engineering Value

This PTFE flat washer is engineered to address critical challenges in high-temperature and chemically aggressive settings, such as chemical processing, aerospace, and automotive systems. Its PTFE plastic composition offers innate resistance to a wide range of chemicals, preventing swelling or failure that plagues metal or rubber alternatives. The 0.344" ID and 1.125" OD ensure precise alignment with 5/16" screw size fasteners, minimizing loosening under thermal cycling. With a maximum temperature of 500°F, it sustains performance in ovens, engines, or industrial machinery, while the flat washer design provides even load distribution to protect surfaces and bolts from stress concentrations. This makes it a reliable choice for engineers seeking longevity and compliance in harsh operational environments.
