Professional Applications & Engineering Value

This Santoprene rubber flat washer delivers critical engineering solutions where standard metal washers fall short. The thermoplastic elastomer construction provides exceptional sealing performance against moisture, chemicals, and environmental contaminants while effectively damping vibrations that can loosen fasteners over time. The black Santoprene material maintains its mechanical properties across an extensive temperature range from -40°F to 270°F, making it ideal for industrial applications in HVAC systems, automotive assemblies, and outdoor equipment. The precise 0.12" ID and 0.375" OD dimensions ensure perfect compatibility with No. 6 screw sizes, while the controlled thickness variation guarantees consistent compression and reliable performance in gasketing, spacing, and insulation roles.
