Holedall
Holedall couplings, regardless of coupling style, are never to be used for steam service at any pressure. Holedall fittings
listed below 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 recommendations. In addition, Internally Expanded Holedall couplings are not to be used with
plastic lined chemical hose. Consult Dixon for recommendations on usage.
Holedall couplings (Externally Swaged), to perform satisfactorily, must be applied properly in accordance with Dixon's assembly
procedures, using correct die and ferrule for that particular hose end OD. Dixon's Die and Ferrule Recommendation Guide is
to be used to select correct dies and ferrules. If you do not have the updated Die and Ferrule Recommendation Guide, consult
the Dixon factory. Strict adherence to ferrule OD range (Internally Expanded) for each hose end to be assembled is essential for
satisfactory performance.
Note: Hose service working pressure (including surges and spikes) is never to exceed the maximum recommended working
pressure for the fitting (reference chart below)*. 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 Compatibility
Chart on pages 600-605 or the Dixon factory for material compatibility. For applications other than the ones listed, please
consult the Dixon factory.
Standard Fittings
Recommended for use on most one and two wire braid reinforced hoses, fiber reinforced (braided or spiraled) with or without
helical wire such as: oil suction and discharge hose, barge and dock loading and unloading hose as well as L.P. gas hose,
anhydrous ammonia hose, acid chemical hose and high pressure air and water hose.
Long Style Fittings
Recommended for use on hose as listed under standard fittings where additional retention is required due to higher working
pressures or end pull. Consult maximum working pressure chart or call the Dixon factory.
Holedall II Fittings
Recommended for Royalflex 1193 and 1196 hose or hoses with similar construction, having helical wire for a given OD range.
Light Duty Fittings
Recommended for use in the same applications as standard fittings above where lower working pressures are encountered.
Consult maximum working pressure chart or consult the Dixon factory.
Internally Expanded Fittings
Recommended for concrete placement, grout and plaster, food, dairy, pharmaceutical as well as other applications where
increased flow capacity is important. Consult maximum working pressure chart or call the Dixon factory for additional application
and working pressure information.
* The assembly's (hose + coupling) maximum working pressure is the lesser of:
1) The hose rated working pressure, or
2) The coupling rated working pressure
** For hoses which use IXF48-3 to IXF48-5 and IXF64-2 to IXF64-5, consult the Dixon factory for working pressures.
See notes below for specific recommendations.
