When specifying a hose, two temperatures must be identified. One is the ambient temperature, which is the temperature surrounding the hose during use. The other is the media temperature, which refers to the temperature of the substance being conveyed through the hose.
Extreme ambient temperatures can negatively affect the hose cover and reinforcement materials, potentially reducing its service life. Media temperature can have an even greater impact on hose longevity. For instance, rubber loses flexibility when exposed to high temperatures for extended periods, which may lead to performance degradation.
