Professional Applications & Engineering Value

This SBR rubber flat washer is engineered to address common industrial challenges such as vibration-induced loosening, fluid leakage, and component wear. The Durometer 70A hardness offers an ideal balance of flexibility and firmness, effectively absorbing shocks and maintaining seal integrity in machinery, automotive assemblies, and plumbing systems. Its polyester fiber reinforcement enhances tensile strength, preventing deformation under high loads and extending the lifespan of 3/8" screw fastenings. With a 2" OD and 0.406" ID, it ensures precise alignment and even load distribution, reducing the risk of corrosion and fatigue in inch system applications. The black SBR rubber material resists degradation from oils and moderate temperatures up to 170°F, making it a reliable choice for industrial rubber washers in HVAC, manufacturing, and construction sectors where durability and compliance are critical.
