Professional Applications & Engineering Value

This neoprene rubber ribbed washer delivers exceptional engineering value through its specialized design and material properties. The ribbed texture significantly enhances vibration damping capabilities, effectively reducing noise transmission and preventing fastener loosening in machinery and equipment. With its medium soft 40A durometer hardness, the washer provides the perfect balance between flexibility and load-bearing capacity, making it ideal for applications requiring both cushioning and structural support. The press fit mount type ensures secure installation without additional fasteners, while the 1.25" ID and 1.91" OD dimensions provide optimal coverage for 1 1/4" screw size applications. These features combine to create a reliable solution for industrial equipment, automotive assemblies, and machinery where consistent performance under varying loads and temperatures is critical.

Specification Summary & Compliance

This ribbed washer features precise dimensional specifications including 1.25" inner diameter, 1.91" outer diameter, and 0.5" thickness, engineered for compatibility with 1 1/4" screw sizes. The product maintains RoHS 3 (2015/863/EU) compliance and demonstrates reliable performance across a temperature range of 10° to 180°F. With a documented capacity of 35 lbs per mount and deflection of 0.1" at capacity, the washer delivers consistent mechanical performance for industrial applications requiring medium soft hardness (Durometer 40A) characteristics.
