If you use a flexible hose for the repair, refer to the temporary repair procedure of tubes with flexible hoses (this procedure is in this task).
 (2) Cut the tube. Cut and deburr the inner and outer diameters of the ends of the tubes.
 (3) Clean the end of the tube with CLEANING AGENTS (Material No. 11-003).
 (4) Install the fitting.
 (a) Put the nut and the sleeve on the tube.
 NOTE : Make sure that the cutting edge of the sleeve points to____ the end of the tube.
R  (b) Lubricate with HYDRAULIC FLUIDS (Material No. 02-003): - the threads and the mating face of the nut, - the threads of the union.
 (c) Put the end of the tube into the fitting.
 (5) Do the swaging. (Ref. Fig. 247/TASK 20-23-11-991-033)
