These rubber hoses can withstand abnormally high or low temperatures; extreme hot or cold. They remain rigid and flexible under a broad range of temperatures due to the special rubber compounds such as silicone or EPDM. These hoses are essential for automotive engine cooling systems where hot coolant needs to be transferred, as well as industrial ovens or freezers where fluids are contained at high or low temperatures. Their performance in extreme thermal conditions allows them to serve a wide variety of purposes
