Professional Applications & Engineering Value
These SBR rubber flat washers deliver critical engineering solutions for industrial equipment requiring reliable vibration damping and sealing performance. The polyester fiber filler reinforcement provides exceptional compression resistance, preventing deformation under sustained loads while maintaining the Durometer 70A hardness that ensures proper flexibility for uneven surfaces. The precise 1.375" ID x 2.5" OD dimensions create effective seals around 1 1/4" screw size fasteners, preventing fluid ingress and reducing maintenance frequency in machinery, automotive, and construction applications. The black SBR rubber material withstands environmental exposure while the 170°F maximum temperature rating ensures performance in heated industrial environments.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with 1.375" inner diameter and 2.5" outer diameter, these flat washers feature a thickness range of 0.156-0.218" for optimal compression characteristics. The SBR rubber construction with polyester fiber filler meets industrial standards for vibration isolation and sealing applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for industrial procurement.
