S-95630A556 6.8 mm ID x 17 mm OD Plastic Washers

Key Features & Benefits at a Glance

• Extreme temperature resilience for reliable performance from -50°F to 500°F, preventing material failure in harsh environments.
• Superior chemical resistance due to PTFE material, ideal for corrosive industrial settings and extending component lifespan.
• Consistent dimensional stability with precise 6.8mm ID and 17mm OD, ensuring proper fit and load distribution for M6 screws.
• Optimal hardness and durability with Durometer 51D, providing excellent wear resistance and vibration dampening.
• RoHS 3 compliance guarantees environmental safety and meets strict regulatory standards for industrial use.
• Lightweight and non-conductive properties of white PTFE plastic reduce weight and prevent electrical interference.
• Versatile thickness range (2.7-3.3mm) accommodates minor assembly variations while maintaining sealing effectiveness.

Professional Applications & Engineering Value

This PTFE plastic flat washer is engineered to solve critical challenges in demanding sectors like chemical processing, food manufacturing, and aerospace. Its high-temperature resistance up to 500°F and low-temperature capability down to -50°F ensure integrity in thermal cycling, while the inherent chemical inertness of PTFE prevents degradation from aggressive fluids. The metric M6 size with 6.8mm inner diameter and 17mm outer diameter provides precise alignment and even pressure distribution, reducing stress concentrations and bolt loosening. These flat washers are essential for applications requiring reliable insulation, corrosion prevention, and long-term performance under extreme conditions, making them a trusted choice for industrial washers in OEM and maintenance operations.

Specification Summary & Compliance
