Penflex 400 Series helical hose is available in limited range 1/4” – 2” ID. Helical hoses are used in limited applications with the primary benefit being the ability to drain the hoses of liquid media easier than annular hose. Helical hose can be subject to torsion under pressure. Where torsion is likely to occur, annular hoses (specifically P3) is often a superior selection over 400 Series.
