S-94709A155 0.531" ID x 1" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior Sealing Performance: The bonded neoprene rubber seal provides a reliable, long-lasting barrier against moisture, dust, and contaminants, extending equipment life.
• Excellent Corrosion Resistance: Made from 18-8 Stainless Steel, this washer offers outstanding resistance to rust and corrosion in harsh environments.
• Wide Temperature Tolerance: Withstands extreme temperatures from -40°F to 250°F, ensuring consistent performance in both freezing and high-heat applications.
• Enhanced Vibration Dampening: The combination of a metal body and a Durometer 65A neoprene seal effectively absorbs shock and reduces loosening from vibration.
• Precise Fit for 1/2" Screws: The 0.531" ID and 1" OD dimensions ensure a perfect, secure fit, simplifying installation and improving assembly reliability.
• Durable Bonded Construction: The permanent bond between the stainless steel and neoprene prevents seal separation, offering a robust solution for demanding industrial use.
• Clear Visual Identification: The black seal color provides easy identification for quality control and inventory management.

Professional Applications & Engineering Value

This metal bonded washer is engineered to solve critical challenges in industrial sealing and fastening. The 18-8 stainless steel body provides structural integrity and corrosion resistance, while the bonded neoprene rubber seal (Durometer 65A) ensures a tight, resilient seal that compensates for surface irregularities and thermal expansion. It effectively prevents fluid ingress and reduces noise and wear caused by vibration in machinery, electrical enclosures, and automotive assemblies. Ideal for applications requiring a dependable sealed washer that performs under variable pressures and temperature extremes, this component enhances system longevity and reduces maintenance needs in commercial and industrial settings.

Specification Summary & Compliance

This washer conforms to inch system measurements with an Inside Diameter (ID) of 0.531", Outside Diameter (OD) of 1", and a Thickness range of 0.116" to 0.141", designed for use with 1/2" screw size. The seal material is Neoprene Rubber with a hardness of Durometer 65A. Manufactured to standard industrial specifications for dimensional accuracy, it is suitable for general-purpose applications where specific hardness ratings are not critical. The materials used are compliant with common industry standards for performance and safety.
