Pressure Recommendations
1. The chart is intended as a guide only. It only applies to metal couplings as shown for ambient temperature
70°F (21°C)
applications with true ID 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
70°F (21°C)
contact the hose manufacturer or Dixon
®
at
800.355.1991.
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 (RMA)
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 Dixon
®
at 800.355.1991 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).
