S-95630A892 0.141" ID x 0.406" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional high-temperature performance – withstands continuous exposure up to 500°F (260°C), ensuring reliable operation in demanding thermal environments.
• Superior chemical resistance – made from PTFE (Teflon®) plastic to resist corrosive chemicals, acids, and solvents, extending service life in aggressive applications.
• Consistent mechanical properties – maintains Durometer 55D hardness for reliable load distribution and vibration damping without deforming under pressure.
• Precision dimensional fit – 0.141" ID and 0.406" OD ensure optimal alignment and secure fastening with No. 5 screws, reducing installation errors.
• Regulatory compliance assurance – meets RoHS 3 and REACH standards, supporting use in regulated industries and global supply chains.
• Low friction and non-stick surface – minimizes galling and sticking, facilitating easy maintenance and disassembly in repetitive or high-wear scenarios.
• Durable, uniform construction – thickness range of 0.036–0.045" provides consistent sealing and spacing performance across industrial assemblies.

Professional Applications & Engineering Value

Engineered for extreme conditions, these PTFE plastic flat washers deliver critical performance in industrial and chemical processing applications where temperature fluctuations and corrosive media are common. The PTFE material offers near-universal chemical inertness, preventing degradation from acids, bases, and hydrocarbons, while the flat washer design ensures even pressure distribution under No. 5 screw heads. This combination solves common failure points—such as seal leakage, fastener corrosion, and thermal expansion mismatches—in equipment like chemical pumps, valves, heat exchangers, and food processing machinery. By integrating a high-temperature rating of 500°F with low moisture absorption, these washers maintain dimensional stability and electrical insulation properties, reducing downtime and replacement costs in critical systems.

Specification Summary & Compliance
