Professional Applications & Engineering Value

This SBR rubber flat washer delivers critical engineering solutions for industrial applications where vibration resistance and sealing performance are paramount. The polyester fiber reinforced construction maintains dimensional stability under compression, preventing flange distortion in heavy machinery, piping systems, and structural assemblies. With its Durometer 70A hardness and 3" outer diameter, it effectively distributes clamping forces while creating reliable seals against moisture, dust, and air infiltration. The black SBR rubber material offers excellent resilience in industrial environments with continuous exposure to temperatures reaching 170°F, making it ideal for HVAC systems, automotive assemblies, and manufacturing equipment requiring durable inch system washers.
