HOSE, COUPLINGS, AND FITTINGS 



damage the hose, the pull for the flexible- bead coupling being 

 50 Ib. as against approximately 250 Ib. for the rigid-bead 

 coupling. This insures the parting of the flexible-bead 

 coupling before the strain is sufficient to damage the hose. 

 Couplings showing this bead are shown in Fig. 3. The piece 

 number of the lf"X22" hose with hose protecting coupling, 

 complete, is 32,015; that of hose protecting coupling, com- 

 plete for lf"X22" hose, is 28,207.
