S-95630A843 0.344" ID x 1.5" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional heat resistance – withstands continuous operation up to 500°F, ideal for high-temperature industrial environments.
• Superior chemical inertness – PTFE material resists corrosive chemicals, acids, and solvents, ensuring long-term reliability.
• Optimal load distribution and vibration damping – 1.5" OD and 0.344" ID provide a broad bearing surface to prevent loosening and component damage.
• Consistent performance under stress – Durometer 55D hardness offers durability without compromising flexibility for secure sealing.
• Precision dimensional fit – inch-system sizing (for #5/16 screws) ensures easy installation and reliable alignment in assemblies.
• Regulatory compliance for global markets – meets RoHS 3 and REACH standards, supporting use in regulated and sensitive applications.
• Non-stick, low-friction surface – white PTFE construction prevents adhesion and simplifies maintenance in processing equipment.

Professional Applications & Engineering Value

Engineered for demanding settings, this PTFE plastic flat washer delivers critical performance where thermal stability and chemical resistance are paramount. Its high-temperature rating (500°F) makes it suitable for automotive, aerospace, and chemical processing systems, preventing degradation under thermal cycling. The flat washer design evenly distributes clamp load, reducing stress concentrations on fastened joints. With excellent dielectric properties and minimal moisture absorption, it maintains insulation and dimensional integrity in electrical enclosures or fluid handling systems. The 5/16" screw size compatibility and standardized inch dimensions ensure interchangeability, while the white PTFE material offers visual cleanliness for food, pharmaceutical, and semiconductor applications.
