After pressure testing hoses, what is the maximum drying temperature?

After pressure testing hoses, you want to dry them with modest heat so moisture is removed without risking damage to the hose materials. Hose construction combines rubber, fabric reinforcements, and adhesives. These components can be damaged if exposed to high heat, so drying too hot can cause rubber to degrade, adhesives to break down, or the fabric to lose strength. A drying temperature of 150°F provides enough heat to evaporate remaining moisture while staying gentle on the hose, fittings, and bonds. Temperatures like 100°F may dry too slowly, while 200°F or 250°F are risky and can harm the hose.
