Professional Applications & Engineering Value
This M12 metal bonded washer combines zinc-plated steel structural integrity with Buna-N rubber seal flexibility to solve critical industrial sealing challenges. The metal bonded construction eliminates seal displacement during high-vibration operations, while the temperature-resistant design maintains performance from freezing conditions to elevated heat environments. Engineered for hydraulic systems, pneumatic equipment, and industrial machinery, this washer prevents fluid leakage at pressures up to 7100 psi, reducing downtime and maintenance costs. The metric dimensions ensure precise fit with M12 fasteners, providing reliable sealing solutions for OEM manufacturing and maintenance applications where pressure integrity and environmental resistance are paramount.
Specification Summary & Compliance
Manufactured to metric system standards with precise 11.7mm ID, 19.3mm OD, and 1.1-1.4mm thickness tolerances. The zinc-plated steel body meets industrial hardness requirements at Rockwell C26, while the Buna-N rubber seal maintains Durometer 85A hardness throughout the specified temperature range. Complies with industry standards for metal bonded washers and contains materials meeting RoHS and REACH environmental directives for industrial use.
