Our Products

Founded in 1902, we are an ISO 9001-certified manufacturer of flexible metal piping solutions, offering a broad range of metal hose, hose assemblies, braid, bellows and expansion joint products along with complementary services, including sales and welder training, engineering support, prototyping, testing and contract braiding.

Metal Hoses

From our lightweight, flexible P3 Series to the triple-braided heavy-duty 1400 Series, Penflex’s metal hoses can accommodate applications from the least to most demanding.

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 won’t do.

There may be axial movements or space constraints, we could be working with very large diameter applications, or users may want a more cost effective option when exotic materials are required.

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