Corrugated metal hose

Our standard corrugated metal hose is made by forming annular corrugations into a thin wall welded tube. It is pressure tight and ideal for vibration, continuous flexing and when properly designed and installed, for thermal expansion and contraction. Helical hose is also available. We provide T-321 stainless steel, T-316 stainless steel, bronze, monel, and hasteloy corrugated hose.
