Flexible Metal Hose Selection | Parker

Parker Metal Hose Assemblies

Parker Flexible Metal Hose assemblies are designed for applications involving chemicals and high temperatures. Due to the extreme nature of applications where these hoses are typically used, they are only available as factory welded assemblies. The Parker metal hose assemblies are tested and guaranteed leak-free, full vacuum hose solutions.

9A and 9M Parflex Metal Hose products are constructed with a hydroformed corrugated stainless steel core tube. Hydroforming, which utilizes high pressure water to form the corrugations, minimizes residual stress in the metal and maintains a consistent tube wall thickness throughout the hose. Any hose assembly is only as good as its weakest link. In the case of a metal hose assembly, the weakest link can be the welding process. The proprietary methods of seam and butt welding, as well as fitting attachment, utilized in Parker assemblies are second to none and yield a consistent, reliable, leak-free connection.


Product Features:

  • High temperature operation - maintains fire safety integrity up to 1200°F
  • Leak free weld connection & zero permeation
  • Maintains shape under full vacuum
  • Available in I.D. sizes 1/4" to 6"

Pressure Rating vs. Minimum Bend Radius of Parker Flexible Metal Hoses

The minimum bend radius of flexible metal hoses increases with pressure. Bend radius is measured from the center line of the hose, and pressure is measured at an ambient temperature of 70°F.

Look for tables describing this relationship on each metal hose page.

Hose and hose fittings series must be correctly matched. Using any fittings other than those specifically designated by the hose manufacturer for use with each specific hose can lead to hose assembly failure. Hose assembly failures have lead to damage, injury and death.
