Bellows

AMETEK FMH manufactures a wide range of custom-designed bellows for use in the high-temperature, high-pressure, and high-vibration transfer of air and fluids. Bellows are formed from tubes manufactured to radiographic standards and then incorporated into braded metallic hose assemblies, flexible (ball and gimbal style) joints, in tube and duct assemblies, or are used in a variety of direct applications. Materials used include: Stainless Steel, Inconel, Titanium and Aluminum. Sizes range from ¼” to 36” ID. As an industry leader and innovator in bellows design and manufacture, our product is used in challenging applications throughout space, military and commercial aerospace.
