Masterflex™

Masterflex™ is Hose Master’s close pitch metal hose. It is manufactured using the same high quality process used to make Annuflex™ hose, but the number of corrugations per foot is increased to allow for greater flexibility.

Explanation of Masterflex™ Part Numbers:

AF ____________  5  ____________

Notes:

  • The minimum bend radius is measured from the centerline of the hose
  • The working pressure decreases with temperature – see derating factor
  • For rapid pressure fluctuations consult the factory
