What is a Rubber Washer ?

A washer is a mechanical seal used for sealing two mating parts. A rubber washer has a flat ring like structure having an outside diameter (O.D), inner diameter (I.D) and thickness which is used to create tight seal between the two parts. Along with sealing, it helps in eliminating vibration and sound between the parts. Although both perform similar functions, rubber washers are generally preferred over metal washers because they ensure tighter sealing as well as avoid corrosion when exposed to humid atmosphere or where the application is in contact with water or corrosive fluids.
