How does a seal washer work?

A seal washer, also known as an O-ring or sealing ring, is a small circular component made of rubber or silicone. It creates a watertight seal between two mating surfaces, preventing leaks or fluid loss. 

The seal washer works by being compressed between the two surfaces, filling any gaps or irregularities and creating a tight seal. The elasticity and flexibility of the material conforms to different surfaces and provide a reliable seal even under pressure or varying conditions.

When do you replace them in your pressure washer?

Replace seal washers when they become worn, damaged, or lose their sealing properties. They shouldn’t leak or drip at connection points, decrease water pressure, or have difficulty in maintaining a steady stream of water. Over time, seal washers can deteriorate due to usage, exposure to chemicals or high temperatures, or general wear and tear.
