What Does a Seal Do?
Posted on 2017/02/28 | Cliff | SealsSeals are everywhere around us in our modern world but often hidden. Even at home, there are quite a few examples – from the kitchen to the garden to the car. In simple terms… seals either keep good stuff in, bad stuff out, or provide a separation barrier between things.
Some everyday examples
- In the kitchen: your oven has a rubber seal around the door to keep the heat in while allowing you to get things in and out for cooking, and then you ‘seal in the goodness’ of the food with an air-tight container (with a sealing lid)
- In the garden: your water spray gun connects to your hose fitting with a rubber seal to hold the water pressure and stop leaking, so you can control the watering of your garden.
- In your car: the doors all have a moulded rubber seal around them to keep the rain out, while allowing you to get in and out.
