How Do Bubble Gaskets Differ from Wedge Gaskets?
Bubble gaskets and wedge gaskets differ mainly in their shape, design, and the sealing applications they are suited for.
-
Shape: Bubble gaskets feature a rounded, bubble-like profile that provides a larger surface area for sealing. This shape helps distribute pressure evenly. In contrast, wedge gaskets have a triangular or wedge shape that creates a tighter fit in joints and allows for effective sealing under compression.
-
Material and Flexibility: Bubble gaskets are typically made from softer materials like rubber or foam, making them more flexible. This flexibility enhances their ability to conform to irregular surfaces. Wedge gaskets are often made from harder materials, such as metals or hard plastics, which makes them less flexible but more durable in high-pressure applications.
-
Pressure Handling: Bubble gaskets can accommodate a range of pressures but are generally best for low to moderate pressure environments. Wedge gaskets excel in high-pressure applications due to their compressed design, which allows them to fill gaps effectively.
-
Installation: Installing bubble gaskets is usually simpler because they can be placed in a variety of joint configurations. Wedge gaskets may require more precision during installation to ensure an effective seal.
