• Excellent Temperature Resistance - Withstands extreme conditions from -40°F to 250°F, maintaining seal integrity in both freezing cold and high-heat applications.
• Enhanced Vibration Damping - Durometer 65A seal hardness offers optimal flexibility for absorbing shocks and preventing fastener loosening under dynamic loads.
• Corrosion-Resistant Construction - 18-8 stainless steel base material ensures long-term durability and resistance to rust in harsh industrial settings.
• Precise Fit for 1/4" Fasteners - 0.312" ID provides accurate alignment with standard 1/4" screws, ensuring proper installation and uniform pressure distribution.
• Dual-Material Advantage - Metal-rubber bonding combines the strength of stainless steel with the sealing properties of neoprene for comprehensive protection.
• Versatile Industrial Application - Black neoprene seal offers UV resistance and aesthetic compatibility while maintaining performance across various sectors.

Professional Applications & Engineering Value

This metal bonded washer solves critical engineering challenges where both mechanical strength and environmental sealing are required. The 18-8 stainless steel construction provides structural integrity and corrosion resistance, while the permanently bonded neoprene rubber seal (Durometer 65A) creates an impermeable barrier against fluids, gases, and particulate contamination. Ideal for industrial applications in automotive assemblies, electrical enclosures, machinery guards, and outdoor equipment, this washer prevents leakage and protects sensitive components from environmental damage. The combination of materials ensures reliable performance in temperature-resistant scenarios ranging from arctic conditions to moderate heat exposure, making it particularly valuable for applications subject to thermal cycling and vibration resistance requirements where traditional washers would fail.

Specification Summary & Compliance

This heavy-duty metal bonded washer features precise dimensional specifications with 0.312" inner diameter for 1/4" screw applications and 0.75" outer diameter for optimal load distribution. The component maintains consistent thickness between 0.111" and 0.150" for uniform compression. Manufactured using 18-8 stainless steel bonded with black neoprene rubber seal material rated at Durometer 65A hardness. The assembly is designed to meet industrial standards for bonded seal washers and complies with relevant material specifications for stainless steel and synthetic rubber components used in industrial sealing applications.
