What is the maximum temperature to dry hoses after the test?

Drying hoses after testing requires a balance between removing moisture and protecting the hose materials. Heat speeds evaporation, but hoses are made of rubber compounds, fabric reinforcements, and adhesive bonds at the couplings, which can be damaged by excessive heat. Keeping the drying temperature at about 150°F (65°C) provides enough heat to dry the hose without risking degradation, softening, or weakening of the construction. Lower temperatures would dry more slowly, while higher temperatures like 180°F can harm the hose.
