Read this before making any hose assemblies with permanent ends!

Ferrule crimp recommendations on this app are only a guide and may not apply to every coupling application. In some instances, alternative crimp diameters may be needed.

The recommendations on this site are to be used with Dixon couplings only. Failure to use Dixon components and proper coupling techniques may results in product failure, serious injury, invalidation of the specified working pressure or failure of the finished assembly to perform as intended.

The recommendations on this app are for crimping Dixon couplings to hose with a rubber cover or with most hose tube materials. Crimp dimensions apply to standard length stems and ferrules only. For alternative coupling recommendations or attachment methods for hoses having an unconventional tube or liner (PTFE, Urethane, etc.) or for rubber hose having a very thin wall contact Dixon's Engineering Staff at 800.355.1991 or send an email to

Hoses react differently during the crimping process because there are variances in hose constructions. Some variables include textile braid vs. wire braid, hardwall vs. softwall, presence or lack of helical wire as well as differences in types of hose covers and tubes. These variables vary from one hose manufacturer to the next, as a result, we recommend maintaining accurate records for each King Crimp coupling application.

Holedall Situations to Avoid:

  • Do Not attach any of the King Crimp couplings listed in this app to steam hose.
  • Do Not use any King Crimp couplings for steam applications regardless of pressure.
  • Do Not use any King Crimp couplings for applications where the media temperature and pressure exceeds Dixon's recommendations. For temperatures and pressures in excess of those listed contact Dixon and the hose manufacturer.

Every length of hose, after assembly, should be tested. Testing should be done in accordance with the Association of Rubber Products Manufacturers.
