S-95630A240 0.197" ID x 0.28" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional high-temperature performance up to 500°F, ensuring reliable sealing and load distribution in extreme heat environments without degradation.
• Superior chemical resistance due to PTFE material, preventing corrosion and maintaining integrity when exposed to harsh chemicals and solvents.
• Consistent dimensional stability with precise ID (0.197") and OD (0.28") for secure fit on No. 8 screws, reducing assembly errors and improving joint reliability.
• Optimal hardness (Durometer 55D) provides excellent vibration damping and surface protection, minimizing damage to connected components.
• Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use in global industrial applications.
• Lightweight and non-corrosive properties make it ideal for applications where metal washers could cause galvanic corrosion or add unnecessary weight.
• Wide thickness tolerance (0.045-0.055") allows for flexibility in compression settings, accommodating minor variations in assembly while maintaining performance.
