  • Item Features
Intended for fuel delivery service; commonly used in the transfer of fuel to homes, airplanes, ships, etc and recommended for discharge and suction service
  • Couplings are compact, light and streamlined to eliminate catching on curbs and shrubs
  • Female has octagonal facets for tightening with a wrench
  • Female 1-1/2 in and larger sizes 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
  • Designed for internal expansion only
  • Stems are machined from bar stock or solid brass forgings
  • 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
  • Hand and electrically operated installation equipment is available
  • Do not interchange with other manufacturer's fittings
  • 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
  • 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
  • For applications other than the ones list, please consult Dixon
