Metal Hoses

From lightweight, flexible metal hose to triple- and quadruple-braided heavy-duty high pressure hose, our hose solutions support a wide range of industrial and high-purity applications.

Using different alloys, wall thicknesses, diameters, pitches and corrugation counts allows us to tailor products to meet various temperature, pressure, movement, and corrosion resistance requirements.

Expansion Joints

Sometimes a metal hose wonโ€™t do. 

Our expansion joints are engineered to manage axial and compound movements, vibration, and misalignment. 

For when an expansion joint is the appropriate solution, Penflex designs and manufactures a variety of components to meet customer needs.
