Rubber washers stop leaks by creating a barrier between two surfaces that prevents water from passing through. When a rubber washer is compressed between two surfaces, it fills the gaps and conforms to the shape of the surfaces. This creates a tight seal that blocks the water flow.
However, rubber washers are not foolproof and can fail over time. Some of the factors that can cause rubber washers to leak are:
- Wear and tear: Rubber washers can wear out due to friction, abrasion, or corrosion. This can reduce their thickness, elasticity, or integrity, making them less effective at sealing.
- Temperature changes: Rubber washers can expand or contract due to changes in temperature. This can cause them to lose their shape or fit, creating gaps or cracks that allow water to leak.
- Chemical exposure: Rubber washers can react with certain chemicals or substances that come in contact with them. This can cause them to degrade, discolor, or deteriorate, affecting their performance and durability.
- Improper installation: Rubber washers can leak if they are not installed correctly or securely. This can happen if they are not matched with the right size, shape, or material of the surfaces they are sealing. It can also happen if they are over-tightened or under-tightened, causing them to deform or loosen.
