S-95630A551 3.4 mm ID x 7 mm OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional temperature resilience for stable performance in environments ranging from -50°F to 500°F, reducing failure risks in thermal cycling applications
• Superior chemical and corrosion resistance due to PTFE material, ensuring longevity in harsh industrial settings
• Precise dimensional fit with 3.4mm ID and 7mm OD for reliable seating on M3 screws, minimizing assembly misalignment
• Consistent load distribution from uniform 0.5-0.6mm thickness, helping prevent surface damage and loosening under vibration
• Durable mechanical properties with Durometer 51D hardness, offering excellent wear resistance and repeated use capability
• Regulatory compliance assurance with RoHS 3 standards, supporting eco-friendly and safe manufacturing practices
• Low friction and non-stick surface for easy installation/removal and reduced maintenance downtime

Professional Applications & Engineering Value

Engineered for demanding industrial scenarios, these M3 PTFE flat washers address critical challenges in high-temperature and chemically aggressive environments. The PTFE plastic construction delivers inherent non-conductivity and minimal moisture absorption, making them ideal for electrical insulation and fluid handling systems. With a metric system design (3.4mm ID × 7mm OD), they ensure precise compatibility with M3 screw sizes in automated assembly lines, reducing rework. The white color allows for easy visual inspection and cleanliness control in regulated industries like food processing or pharmaceuticals. By maintaining integrity across extreme thermal swings (-50°F to 500°F), these washers prevent galling and seizure, extending equipment service life and lowering total cost of ownership.

Specification Summary & Compliance
