Gaskets and O-Rings
Gaskets and O-rings help secure a water-tight installation. Gaskets are physical devices - often in a ring shape or designed to fit around an element or immersion heater - that keep a solid seal when the part or item is running. In practice, these will often fit along or wrap around an element or component, and help ensure air-tight sealing when the part or component is in use. This helps ensure that water does not leak out and cause any damage that would follow. Thus, Gaskets fulfil a vital role in a water heater by keeping the unit air-tight and pressure-controlled.
