A sealing washer is a metal disk with a concentric hole. It is placed beneath a nut, an axle bearing, or a joint to support a fastener like a screw; also, it functions as a spacer or lock. The sealing washer provides greater protection to relieve friction, prevent leakage/loosening, isolate or distribute pressure.
Different types of sealing washers have their uses. For example, a star washer is helpful when the material is soft enough to allow the washer to adhere, and a flat washer is to disburse the compression of the nut or bolt freely, etc.
The sealing washer is typically installed between two mating surfaces to create a tight seal.
The purpose of a sealing washer is to prevent fluid or gas from leaking between two mating surfaces. It creates a seal by deforming under pressure, filling any gaps or irregularities in the mating surfaces and creating a barrier against leakage.
Sealing washers are used in a wide range of applications, including automotive engines, plumbing fixtures, hydraulic systems, and industrial equipment.
The most common materials used for sealing washers are rubber, silicone, nylon, and metal, such as aluminum or copper. The choice of material depends on the application, as different materials have different properties such as temperature resistance, chemical resistance, and durability.
A damaged sealing washer may result in fluid or gas leakage, which can be detected by visual inspection or by checking for a decrease in pressure or fluid levels. A damaged sealing washer may also cause abnormal sounds, vibrations, or performance issues in the system it is used in.
If a sealing washer is damaged or fails to create a proper seal, it can result in leaks that can cause damage to the surrounding components or lead to system failure. In some cases, it can also pose safety risks, such as gas leaks that can lead to fires or explosions.
