  • Male has octagonal facets for tightening with a wrench
  • The stem is expanded to nominal ID of hose for a rigid, uniform, full-flow area
  • Couplings are pre-lubricated for assembly
  • Stems are machined from bar stock or solid brass forgings
  • Designed for internal expansion only

Applications: For discharge and suction service and commonly used in the transfer of fuel to homes, airplanes, ships

Safety Notes:

  • Do not interchange with other manufacturer's fittings.
  • Designed for internal expansion only.
  • Dixon® Holedall stems and ferrules are specifically designed to be used together as a coupling system.
  • Do not use a wrench or vice on ferrule.
  • Holedall couplings, regardless of coupling style, are never to be used for steam service at any pressure.
  • Holedall fittings are not to be used with cable reinforced high-pressure hose, 4 or 6 braid wire hydraulic hose or any other service not listed in the recommendations.
  • Consult Dixon® for recommendations on usage.
  • Strict adherence to ferrule OD range (internally expanded) for each hose end to be assembled is essential for satisfactory performance.
  • Hose service working pressure (including surges and spikes) is never to exceed the maximum recommended working pressure for the fitting.
  • The assembly's (hose + coupling) maximum working pressure is the lesser of the hose rated working pressure or the coupling rated working pressure.
  • Media being transported through the hose should be compatible with the stem material.
  • Compatibility of ferrule material with the environment in which it will be used is recommended.
  • Consult the Compatibility Chart or the Dixon® factory for material compatibility.
  • For applications other than the ones list, please consult Dixon®.
