Recommended Couplings: High Pressure 1″to 1-1/2″ for air service if the working pressure exceeds 150 psi. High Pressure, Short shank, universal, or Combination nipples all other sizes. Crimplok universals.
All coupling recommendations are to be used as guidelines and are derived from past user preference. In some cases the preferred coupling is of a lesser pressure rating then the hose.
Never exceed the working pressure of the lowest rated component in the assembly.
