S-95630A903 0.535" ID x 2.5" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional heat resistance for reliable performance in high-temperature environments up to 500°F, preventing deformation and failure under thermal stress.
• Superior chemical resistance due to PTFE material, ensuring long-term durability and protection against corrosive substances in industrial settings.
• Consistent hardness (Durometer 55D) provides optimal load distribution and vibration damping, reducing wear on connected components.
• Precision dimensional fit with 0.535" ID and 2.5" OD for secure placement on 1/2" screws, minimizing misalignment and installation errors.
• Regulatory compliance with RoHS 3 and REACH standards, ensuring safe use in global markets and environmentally sensitive applications.
• Versatile thickness range (0.047-0.080") allows for fine-tuning in assembly to accommodate varying gap and pressure requirements.
• Non-conductive and low-friction properties of white PTFE plastic help prevent galvanic corrosion and ease maintenance in electrical or mechanical systems.
