Professional Applications & Engineering Value

This PTFE plastic flat washer delivers critical engineering solutions for demanding industrial applications where temperature extremes and chemical exposure compromise conventional washers. The high-temperature 500°F rating makes it ideal for thermal processing equipment, automotive systems, and chemical processing machinery where heat resistance is paramount. The chemical-resistant properties of PTFE material protect against corrosive fluids and aggressive environments that would degrade metal or standard plastic washers. With precision inch system dimensions (2" OD, 0.531" ID) specifically engineered for 1/2" screw size applications, this washer ensures secure fastening while preventing galvanic corrosion in mixed-material assemblies. The consistent Durometer 55D hardness maintains sealing integrity under vibration and pressure fluctuations, making it valuable for pump systems, valve assemblies, and high-temperature piping applications where reliability cannot be compromised.
