Rubber Washers

A rubber washer is defined as a thin disk made of rubber with a hole in the middle.

The washer is normally used to support the weight of a threaded fastener.

It is also used as a spacer, spring, wear pad, pre-load indicating device as well as locking device.

Washers are made of various materials like metal, plastic, rubber. A common material is rubber.

Rubber washers are used in taps or valves where they act as the seal that prevents or closes the flow of liquid or gas.

All washers have an outer diameter (OD) about twice their inside diameter (ID).

 Rubber gaskets which are used in taps to stop the flow of water are also sometimes referred to as washers because they look similar. But, washers and gaskets are usually made differently and designed for different functions.
