Flexible Metal Hoses

AMETEK FMH provides a wide range of build-to-print and custom-designed flexible metal hose assemblies. Our all-metallic hose assemblies are made to endure high-pressure, high-temperature, and high-vibration environments. They are created from formed bellows, braid wire and machined fittings, with additional rigid tube sections as required. Diameters range from ¼” to 10” ID. Braid wire is Stainless or Inconel for most applications but can be produced using Titanium. As one of the longstanding and premier manufacturers of flexible metal hose assemblies, our products are used by air framers, engine manufacturers and system suppliers, able to meet or exceed AS1424 standards as needed, and made to the highest industry requirements for lifecycles and performance.
