Nitrile Chemical Hose Specifications

Physical Properties
Manufacturers specify the tensile strength of the nitrile chemical hose. For instance, nitrile chemical hoses used for firefighting purposes should have a tensile strength of at least 1,500 PSI. The hose's inner liner and cover should have an elongation of 500 percent. The inner liner should not stay lengthened by more than 20 percent on a long-term basis. Manufacturers' specifications also typically state how the nitrile chemical hose responds to an accelerated aging test and its adhesion properties.
Safety SpecificationsA nitrile chemical hose also comes with safety specifications. Manufacturers typically specify what sort of safety it provides in terms of abrasion resistance, cold resistance, heat resistance and kink resistance. For instance, the specifications state what sort of cold temperature the hose can withstand. This is important for firefighting applications, and hoses used for firefighting should be able to withstand cold of up to minus 50 degrees Fahrenheit. In terms of heat resistance, these hoses should be able to withstand heat of up to 1,200 degrees Fahrenheit.
Other SpecificationsOther performance specifications for a nitrile chemical hose include its ozone resistance and chemical resistance. These hoses are likely to be exposed to seawater and chemicals such as alkalis and acids. Such exposures should not impact the performance of the hose. Manufacturers also provide information about the weight of the hose, its coil diameter, its swelling capacity, its color, its length and any warranty they provide.
