Professional Applications & Engineering Value
This SBR rubber flat washer delivers critical engineering solutions for industrial equipment requiring reliable sealing and vibration isolation. The polyester fiber reinforcement addresses common failure points in heavy-duty applications by preventing material deformation under sustained compression. With its Durometer 70A hardness, the washer creates optimal sealing force while accommodating surface irregularities in metal assemblies. The black SBR rubber composition combined with fiber filler resists oil, wear, and environmental factors, making it ideal for automotive, machinery, and construction applications where vibration dampening and environmental sealing are paramount. The 170°F temperature rating ensures performance stability across most industrial operating conditions.
Specification Summary & Compliance
Manufactured to inch system dimensions with 1.5" ID, 3.25" OD, and thickness range of 0.156-0.218". Designed specifically for 1 3/8" screw sizes with Durometer 70A hardness rating. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international industrial safety and environmental standards for hazardous substance restrictions.
