ApplicationsIntended for fuel delivery service. Commonly used in the transfer of fuel to homes, airplanes, ships, etc.Recommended for discharge and suction service.UseFor use with Brass internally expanded permanent couplingsH520 fittings are design for internal expansion only.NoteHand and electrically operated installation equipment is available.Safety notesDo 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 ferruleHoledall 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. Consult the Compatibility Chart for material compatibility.WARNING: This product contains a chemical known to the State of California to cause birth defects or other reproductive harm.
