Professional Applications & Engineering Value

This SBR rubber flat washer delivers critical engineering solutions for industrial applications requiring reliable sealing and vibration isolation. The Durometer 70A hardness provides the ideal balance between flexibility and compression resistance, creating effective seals against moisture, dust, and air infiltration in 3/4" screw assemblies. The polyester fiber filler reinforcement addresses common failure points in standard rubber washers by preventing extrusion and maintaining dimensional stability under sustained bolt loads. With a 170°F maximum temperature rating, these washers perform consistently in HVAC systems, machinery enclosures, and outdoor equipment where thermal cycling and environmental exposure challenge conventional sealing components. The precise 0.812" inner diameter ensures proper centering while the generous 1.469" outer diameter distributes clamping forces effectively across joined surfaces.
