S-93786A125 5.8 mm ID x 11.3 mm OD High-Pressure Bonded Sealing Washers For Screw Heads

Key Features & Benefits at a Glance

• Superior leak prevention with permanently bonded Buna-N rubber seal for reliable fluid and gas containment
• Exceptional pressure resistance handling up to 12,800 PSI for fluids and 200 PSI for gases in demanding applications
• Wide temperature tolerance from -30°F to 220°F for stable performance across extreme environmental conditions
• Enhanced durability with zinc-plated steel construction providing corrosion resistance and Rockwell C26 hardness
• Optimized vibration resistance through the bonded rubber-to-metal design that maintains seal integrity under mechanical stress
• Precision dimensional control with 5.8mm ID and 11.3mm OD ensuring perfect fit for M6 fasteners in metric assemblies
• Long-lasting seal performance with Durometer 85A Buna-N rubber offering ideal balance of flexibility and compression resistance

Professional Applications & Engineering Value

These M6 metal bonded washers deliver critical sealing solutions where conventional washers fail. The zinc-plated steel base provides structural integrity while the Buna-N rubber seal creates an impermeable barrier against fluids and gases. Engineered for industrial applications involving hydraulic systems, pneumatic equipment, and machinery subjected to vibration, these washers solve common leakage problems in high-pressure environments. The metric dimensions (5.8mm ID, 11.3mm OD) ensure compatibility with standard M6 fasteners, while the temperature range from -30°F to 220°F makes them suitable for both cryogenic and elevated temperature operations. This combination of metal strength and rubber flexibility addresses the dual challenge of maintaining bolt tension while preventing fluid ingress in demanding industrial settings.

Specification Summary & Compliance

These metric washers feature precision dimensions with 5.8mm internal diameter, 11.3mm outer diameter, and 1.1-1.4mm thickness specifically engineered for M6 screw applications. The construction combines zinc-plated steel with Rockwell C26 hardness and Buna-N rubber seals rated at Durometer 85A hardness. Manufactured to meet industry standards for bonded washers, these components are suitable for applications requiring reliable sealing performance. The product complies with relevant industrial specifications for pressure containment and temperature resistance in fluid and gas systems.
