    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®.
