Angle of Orientation (C) is measured from theposition of coupling (B) clockwise to coupling (A). (THAL) Total Hose Assembly Length. (E) Tolerance.
When the coupling angle is correct, finish pushing coupling (B) into the hose.
Install the sleeve.Measuring Permanent Coupling Crimp Diameters
Quality control of finished crimped hose assemblies is maintainedby measuring the crimp diameter. Crimp diameters can be measured usinga micrometer, calipers, caliper measurement system, or a Crimputer.If available, using the crimputer is the most efficient way to makethese measurements. The crimputer automatically averages the fourmeasurements and adjusts the crimp diameter.

(3) 1E1543 Air ConditioningHose.Note: When measuring the crimp diameter, do not take measurementsacross the ridges of the coupling. To ensure accuracy, each measurementmust be taken in the areas between the ridges.Note: Use Crimp Chart, NEEG2746, "Crimp Diameters Chart" (laminatedchart) for crimp diameter specifications.Illustration 32 showsa crimp diameter measurement system which will take four crimp diametermeasurements and calculate the average.
