Professional Applications & Engineering Value

These SBR rubber flat washers deliver critical engineering solutions where standard metal washers fall short. The black SBR rubber material with polyester fiber filler creates an ideal combination for vibration damping in machinery mounts, electrical enclosures, and automotive assemblies, significantly reducing maintenance cycles. The 0.234" ID precisely matches No. 12 screw size requirements while the 0.625" OD provides ample surface coverage for effective sealing against moisture, chemicals, and particulate contamination. With consistent 0.047-0.077" thickness and Durometer 70A hardness, these flat washers maintain compression set resistance in fluctuating temperature environments up to 170°F, making them indispensable for industrial equipment, plumbing systems, and outdoor applications requiring reliable long-term performance.
