Metal bellows are commonly used in sealing applications due to their unique design and material properties. They are highly effective at providing a flexible, leak-proof seal in a variety of demanding environments.

Metal bellows are durable, reliable, and customizable, making them ideal for a wide range of industrial applications, especially in harsh or dynamic environments.

The Scenic^® APB series is specially designed for high-temperature fluid conditions. It uses the expansion and contraction characteristics of metal bellows to achieve high-temperature and high-pressure sealing functions.
