H5231-A-BU Dixon Valve Brass Internally Expanded Permanent Coupling - Scovill Style - Female NPSH - 1-1/2" Hose ID

  • $35.73
  • Recommended for discharge and suction service. Commonly used in the transfer of fuel to homes, airplanes, ships, etc.
  • Designed for internal expansion only.
  • API certified, tested and compliant with API 1629 6th edition.
  • Female has lugs for tightening.
  • 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.
Safety Notes:
  • The working pressure of the 520-H fitting varies with the size of the fitting, the size and construction of the hose and the media being conveyed.
  • Dixon Holedall stems and ferrules are specifically designed to be used together as a coupling system.
  • Designed for internal expansion only.
  • Do not interchange with other manufacturer's fittings.
  • 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.
  • Strict adherence to ferrule OD range (Internally Expanded) for each hose end to be assembled is essential for satisfactory performance.
  • Internally Expanded Holedall Couplings are not to be used with plastic lined chemical hose.
  • 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.
