What is the difference between a door gasket and seal?

A door gasket and a door seal are both components used to create a seal or barrier around a door to prevent air, water, dust, or other elements from passing through gaps or openings. However, there is no strict standardization of terminology, and the usage of these terms can vary depending on context and industry. In many cases, the terms "gasket" and "seal" may be used interchangeably, but there are subtle differences in how they are commonly referred to:

1. Door Gasket: A door gasket typically refers to a flexible, compressible material placed around the edges of a door or door frame. It is often designed to create a seal by compressing against the door frame or threshold when the door is closed. Door gaskets are commonly used in refrigeration units, oven doors, car doors, and other applications to prevent the exchange of air, maintain temperature control, and reduce noise. They are often made of materials like rubber, silicone, or foam.

2. Door Seal: A door seal can refer to a broader category of components used to seal doors. This can include door gaskets, but it may also encompass other sealing mechanisms or materials. For example, a door seal could refer to the weatherstripping used to seal gaps around exterior doors to prevent drafts and moisture intrusion. It can include brush seals, bottom sweeps, and other types of sealing components.

In summary, while the terms "door gasket" and "door seal" are often used interchangeably, a door gasket typically refers to a specific type of sealing component that compresses against the door frame, while a door seal may encompass a broader range of sealing mechanisms and materials used to achieve the same goal. The specific terminology and usage can vary by industry and context.
