Small Rubber Washers For Compact Spaces


Small rubber washers are spacing components that are meant to be paired with compact fastener assemblies. They are used in tight spaces and with small appliances and parts to help preserve material surfaces. They also add damping and cushioning between connections, and will provide other benefits that help preserve the integrity of an assembly.
 

Like conventional small flat washers, these spacing components are fitted around the neck of a screw, bolt, or similar threaded fastener. They can then be positioned between the head of the fastener and the installation surface. They may also be placed between the nut and the installation surface. Some fastener assemblies may use two or more washers, which can be placed on both sides of a connection or in between joined parts.

Small rubber washers are flexible and allow for slight compression. This provides cushioning and force dampening between moving parts. They will prevent squeaking, abrasion, grinding, and retain tension in connected parts. And while they are flexible, they are still sturdy enough to maintain their form among harder materials.

Small rubber washers can be paired with standard metal washers to help grip the heads of fasteners and the surface of a nut. Rubber’s high coefficient of friction and flexible surface amounts to a no-slip, gripping capacity, which stabilizes components in place. This, combined with their shock absorption capabilities, makes them excellent spacing devices in equipment that produces or is regularly subjected to vibration. 

Small washers made from rubber are sometimes used as gaskets or hose washers in narrow pipework, hoses, small spouts, and valves. Rubber is an effective sealing material and washers stamped from it will be useful for preventing leaks and securing the flow of liquids and gases. Small rubber washers may not be an effective replacement for all gaskets, particularly when an o-ring with rounded edged is better suited to seal a threaded or grooved connection.

Small rubber washers can be used in compact electronic applications. Rubber will reliably insulate electricity. Synthetic rubbers made with a variety of polymers can offer enhanced resistance and stability under high temperatures, making them suitable for a broad range of industrial applications.

The measurements that define a rubber washer as small can vary by the specifications of the manufacturer or supplier. Small rubber washers are most commonly round but other shapes can be made.

The thickness of the washer is also an important characteristic. This measurement will determine the clearance of the washer and profile of the assembly. The thicker a washer is, the greater capacity it has for absorbing shock, while thinner washers are more flexible and better able to conform to the shape of connecting surfaces. Rubber washer thickness is also a factor in its elasticity, but this property will vary based on the specific type of rubber. 

Small rubber washers are available in standard dimensions from most fastener retailers. If custom varieties or particularly large quantities are required, it can be more economical to source such washers directly from a stamping manufacturer.      

What Are Small Rubber Washers Used For?

Small rubber washers are placed between threaded fasteners as part of an overall assembly. They are fitted into small spaces or paired with smaller nuts, bolts, and screws. Small rubber washers can also be used as gaskets in tight pipework, valves, spouts, hoses, and other hardware. Through their material properties, small rubber washers can be used to dampen vibration, act as a cushioning barrier between components, prevent leaks, and hold components more firmly in place. 

Where To Get Small Metric Rubber Washers?

Small size metric washers can be acquired from stamping manufacturers and dedicated fastener distributors. Rubber washers are considered standard in terms of material and are available from suppliers of metric spacing components.
