• Superior chemical resistance due to PTFE material, preventing degradation from harsh chemicals and solvents
• Consistent dimensional stability with precise 13mm ID and 24mm OD for perfect fit with M12 screws
• Optimal hardness and durability with Durometer 51D rating, ensuring long service life under compression
• Reliable sealing performance with uniform 2.4-2.7mm thickness for effective load distribution and vibration resistance
• Full regulatory compliance with RoHS 3 and REACH standards, meeting international environmental and safety requirements
• Non-corrosive and electrically insulating properties make them ideal for electrical and chemical processing applications

Professional Applications & Engineering Value

These M12 PTFE flat washers deliver critical engineering solutions where standard metal washers fail. The PTFE plastic construction provides inherent chemical resistance against aggressive solvents, acids, and bases, while maintaining structural integrity at continuous temperatures up to 500°F. This makes them indispensable in chemical processing equipment, food manufacturing machinery, and semiconductor manufacturing where contamination must be avoided. The metric dimensions (13mm ID × 24mm OD) ensure precise fit with M12 fasteners, providing consistent load distribution in high-vibration environments. The white color allows for easy identification in complex assemblies, while the 2.4-2.7mm thickness range accommodates minor surface irregularities for improved sealing performance in flange connections and pressurized systems.

Specification Summary & Compliance

This flat washer features metric dimensions with 13mm internal diameter and 24mm outer diameter, specifically designed for M12 screw applications. The thickness tolerance of 2.4-2.7mm ensures consistent performance across production batches. Manufactured from PTFE plastic with Durometer 51D hardness, these washers meet international standards for high-temperature applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no substances of very high concern above threshold limits. The manufacturing process maintains tight dimensional controls suitable for precision industrial assemblies requiring reliable chemical resistance and thermal stability.
