Hose & Coupling Pressure Recommendations

Mark hose assembly with pressure from this chart or hose working pressure, whichever is lower all pressure
recommendations are in pounds per square inch (psi)

1. This chart is intended as a guide only. It only applies to metal couplings as shown, for ambient temperature
(21°C or 70°F) applications with true I.D. hose. It assumes new Dixon supplied couplings, new Dixon supplied
clamps, new quality hose and proper installation by a qualified assembler using Dixon procedures and
equipment. Temperature can affect the coupling retention. For questions relating to temperatures other than
ambient (21°C or 70°F) contact the hose manufacturer or Dixon.

2. This chart does not apply to non-Dixon products, with used hose, in non-approved or unsupported
applications or in non-standard assemblies.

3. Do not use this chart if it conflicts with the hose manufacturer’s recommendations.

4. All hose assemblies should be pressure tested to hose manufacturers or Rubber Manufacturers
Association (R.M.A.) specifications prior to being put into service.

5. Our test experience indicates that coupling retention can vary with changes in hose design. For pressure
ratings other than those listed and shown, or if questions arise, please call our technical support team
for assistance.

6. All hose assembly components must be compatible with the materials and environments with which they
are to come in contact.

7. Dixon recommends that all hose assemblies be marked with the assembly working pressure and media of
the intended application. Under no circumstances should the assembly working pressure exceed the working
pressure of the lowest rated component (coupling, clamp, ferrule or hose).

8. For further safety information, refer to ‘The Proper Selection, Care, Use & Maintenance of Hose Couplings
& Accessory Items’ pamphlet.
Contact Dixon to request a copy of this literature.

9.  To convert the following pressure recommendations that are stated in psi Divide the psi figure by
14.5 to convert to (bar).

Pressure Recommendations
Mark hose assembly with pressure from this chart or hose working pressure, whichever is lower all pressure
recommendations are in pounds per square inch (psi).

1. This chart is intended as a guide only. It only applies to metal couplings as shown, for ambient temperature
(20°C) applications with true I.D. hose. It assumes new Dixon supplied couplings, new Dixon supplied clamps,
new quality hose and proper installation by a qualified assembler using Dixon procedures and equipment.
Temperature can affect the coupling retention. For questions relating to temperatures other than ambient
(20°C) contact Dixon.

2.  This chart does not apply to non-Dixon products, with used hose, in non-approved or unsupported applications
