Nylon reinforced or polyester reinforced fire hose is secured to a coupling or shank by heating the fire hose to at least 270° F. with a wrap-around electric heating apparatus. The heating apparatus heats the fire hose for the period of time necessary to shrink fit the fire hose to the coupling or shank. Shrink fitting the fire hose to the coupling eliminates pinching of the fire hose and prevents leakage. |
