Recommended Working Pressures
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. Consult factory for recommendations on usage.
Holedall couplings, 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 factory.
Note: Hose service working pressure (including surges and spikes) is never to exceed the maximum recommended working
pressure for the fitting (reference chart below)*. King safety cables are recommended. Media being transported through the
hose should be compatible with the stem material and ferrule material. Consult Compatibility Chart on pages 548-553 or the
factory for material compatibility. For applications other than the ones listed, please consult Dixon factory.
Standard Fittings
Recommended for use on most one and two wire braid reinforced hoses, fiber braided and helical wire reinforced hose, such as:
oil suction and discharge hose, barge and dock loading and unloading hose, L.P. gas hose (consult Dixon for NFPA56 compliant
products), anhydrous ammonia hose, aircraft fueling hose and acid chemical 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 factory.
Holedall II Fittings
Recommended for Royalflex P1193 and P1196 hose or hoses with similar construction, having helical wire for a given O.D.
range.
Light Duty Fittings
Recommended for use in the same applications as standard fittings above except that hose rated working pressure is never to
exceed the maximum recommended working pressure listed in chart above.
* 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 factory for working pressures.
See notes below for specific recommendations.
•
maximum recommended working pressures, in PSI, at 70°F ambient temperature
•
for applications other than the ones listed, please consult Dixon factory
