Professional Applications & Engineering Value

These SBR rubber flat washers are engineered to address common industrial challenges such as vibration-induced loosening, fluid leakage, and material degradation. The polyester fiber reinforcement significantly boosts tensile strength, preventing deformation under constant load—making them ideal for machinery, automotive assemblies, and plumbing systems where 1" screw size fasteners are used. The Durometer 70A hardness offers optimal flexibility for sealing applications while withstanding temperatures up to 170°F, ensuring longevity in high-heat environments. By combining inch system measurements with robust material properties, these washers deliver reliable performance in demanding settings, from manufacturing plants to construction projects, reducing maintenance needs and downtime.

Specification Summary & Compliance

This flat washer adheres to precise dimensional tolerances with an inner diameter of 1.062", outer diameter of 2.5", and thickness ranging from 0.105" to 0.145".
