S-95630A827 0.25" ID x 1.25" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional high-temperature performance – withstands continuous exposure up to 500°F, ideal for thermal cycling environments
• Superior chemical resistance – PTFE material prevents degradation from harsh chemicals, acids, and solvents
• Precise dimensional stability – 1.25" OD and 0.25" ID ensure perfect fit for No. 12 screws with consistent 0.027-0.035" thickness
• Optimal load distribution – Durometer 55D hardness provides excellent compressive strength while maintaining sealing integrity
• Regulatory compliance assurance – meets RoHS 3 and REACH standards for safe use in regulated industries
• Non-contaminating white PTFE construction – prevents galvanic corrosion and maintains purity in sensitive applications
• Low friction surface – reduces torque requirements and prevents seizing in high-temperature assemblies

Professional Applications & Engineering Value

These PTFE plastic flat washers deliver critical performance in demanding industrial settings where conventional washers fail. The PTFE material provides inherent chemical resistance against aggressive fluids and solvents, while maintaining mechanical integrity at 500°F maximum temperature. Engineered with precise 1.25" OD x 0.25" ID dimensions for No. 12 screws, they ensure reliable sealing and load distribution in chemical processing equipment, food manufacturing machinery, semiconductor fabrication tools, and aerospace components. The white PTFE construction eliminates contamination risks in cleanroom environments and prevents galvanic corrosion between dissimilar metals, extending equipment service life in corrosive applications.
