* In Step 1 the (A) dimension in the illustration is for XT hoses ONLY.* For other than XT hoses, dimension (A) is the Hose Insertion Depth (full length of the shell).Crimped couplings should be inspected both visually and dimensionally to be sure of configuration to design specifications. Refer to the above charts for hose crimp length (A) and diameter specifications. For crimp diameter, make two measurements (B) and (C), 90° apart, and average these two measurements. Crimp diameter measurements are to be taken at the middle of the crimp length and at the center of the crimp segment.Air Conditioning Hose Crimping
The crimping procedure for air conditioning hose assemblies is relatively the same for other assemblies with permanent couplings. Refer to SEHS9052. The differences will be identified below. Hose insertion depth for the air conditioning couplings is 40.4 mm (1.59 in).1. Insert hose into coupling to proper depth.2. Position the coupling in the die set such that the coupling shell contact is maintained with the "U-shaped crimp locator" on the die set during the crimping process.It is a good crimp if:* hose cover extrudes some from the hole at the top of coupling. (This ensures that the hose is seated in the coupling).* the hose should not bulge at bottom/skirt of shell.* crimp measurements should be within range in chart below. Do not cut hose with an abrasive saw or other types of rotating blade saws. Use a sharp knife so that the hose is not pinched and a square cut can be attained for proper seating with the coupling.
1. Coupling Tube. 2. Bottom/Skirt of shell. 3. Hose. 4. Coupling Shell View Hole.Installation Angle (Orientation) of Couplings
1. Put assembled coupling (1) in a vise with flange (2) up as shown. Adjust the dial of 7S1125 Protractor (3) to zero. With the dial face of protractor (3) toward the vise, fasten the protractor near the sleeve of the coupling. Adjust
